Trends in High School Vocational/Technical Coursetaking: 1982–1998
By: Karen Levesque
 
This article was originally published as the Executive Summary of the Statistical Analysis Report of the same name. The sample survey data are from the High School and Beyond Longitudinal Study (HS&B), the National Education Longitudinal Study of 1988 (NELS:88), and the High School Transcript Study (HSTS).
 
 

Vocational/technical education is a common component of public high school education in the United States. Among 1998 public high school graduates, 96.5 percent earned at least some credits in vocational/technical education in high school. In addition, the number of credits earned in vocational/technical education by 1998 graduates was not significantly different on average from the number of credits they earned in English and in social studies, and they earned more credits in vocational/technical education than they did in mathematics, science, fine arts, or foreign languages.


This report examines vocational/technical coursetaking among public high school graduates between 1982 and 1998. The report focuses on trends in vocational/technical coursetaking overall, in introductory technology and computer-related coursetaking, and in the ways in which high school students combine vocational/technical and academic coursetaking. The report analyzes these trends by examining high school transcripts for the graduating classes of 1982, 1990, 1992, 1994, and 1998.1 Transcripts provide information on the courses that graduates took in grades 9 through 12. For simplicity's sake, the report refers to this information as "high school coursetaking." With the exception of the section on vocational/technical coursetaking by grade level, which examines coursetaking in each of grades 9 through 12 separately, the report describes the cumulative coursework that graduates took in high school. The report uses the National Center for Education Statistics (NCES) Secondary School Taxonomy (SST) to classify courses into broad course groupings. As figure A shows, the SST classifies high school courses into three main areas (academic, vocational/technical, and enrichment/other) and their curricular subareas.

The vocational/technical curriculum

High school vocational/technical education encompasses three subcurricula: specific labor market preparation or "occupational education," general labor market preparation, and family and consumer sciences education (figure A). Occupational education consists of courses that teach skills and knowledge required in a particular occupation or set of related occupations. Based on SST classifications, occupational education in this report consists of the 10 broad and 18 narrow program areas shown in figure A.

General labor market preparation consists of courses that teach general employment skills that are not specific to one occupational area, such as basic typewriting/keyboarding, introductory technology education, and career preparation and general work experience courses. Family and consumer sciences education consists of courses intended to prepare students for family and consumer roles outside of the paid labor market.2

As of 1998, 90.7 percent of public high school graduates had earned credits in occupational education in high school, 58.8 percent in general labor market preparation, and 44.4 percent in family and consumer sciences education.

Key measures of participation

Seven measures were used to define participation in vocational/technical education:

  • Vocational/technical coursetakers. Graduates earning more than 0.0 credits in vocational/technical education in high school. All of the following groups of students are subsets of this group.
  • Occupational coursetakers. Graduates earning more than 0.0 credits in occupational education in high school. This measure is a subset of the previous measure.
  • Vocational/technical investors. Graduates earning 3.0 or more credits in vocational/technical education in high school. All of the following groups of students are subsets of this group.
  • Occupational investors. Graduates earning 3.0 or more credits in occupational education in high school, regardless of whether they concentrate their occupational coursetaking in a single program area. This measure is a subset of the previous measure.
  • Occupational concentrators. Graduates earning 3.0 or more credits in high school in one of the 10 broad occupational program areas in figure A.3 This measure is a subset of the previous measure. The report also provides information on graduates concentrating (earning 3.0 or more credits) in one of the 18 narrow occupational program areas in figure A.
  • Advanced occupational concentrators. Graduates earning 3.0 or more credits in high school in one of the 10 broad occupational program areas in figure A, with at least 1.0 advanced credit in that program area. Advanced occupational coursework includes second- or higher-level courses and cooperative education courses.4 This measure is a subset of the previous measure.
  • Advanced occupational concentrators with cooperative education. Graduates earning 3.0 or more credits in high school in one of the 10 broad occupational program areas in figure A, with at least 1.0 cooperative education credit in that program area.5 This measure is a subset of the previous measure.

Figure B shows the percentage of 1998 public high school graduates who fell within each participation measure. According to the least restrictive measure—the percentage of public high school graduates who were vocational/technical coursetakers—almost all 1998 graduates (96.5 percent) participated in the vocational/technical curriculum in high school. According to the most restrictive measure—the percentage of graduates who were advanced occupational concentrators with cooperative education—just 4.5 percent of 1998 graduates were counted as participating in vocational/technical education.

Between 1982 and 1998, the primary change in vocational/technical coursetaking was not in the proportion of high school students participating in vocational/technical education but in the amount of vocational/technical education they took. That is, the breadth of vocational/technical coursetaking declined slightly, while the depth of this coursetaking declined more steeply. However, most declines in vocational/technical coursetaking occurred by the early 1990s.

The average number of vocational/technical credits earned by graduates declined between 1982 and 1990, after which there were no statistically significant changes. However, during the 1990s, vocational/technical credits continued to represent a declining share of the total high school credits that graduates earned. This relative decline was due to the fact that public high school graduates earned on average more academic credits and—to a lesser extent—more enrichment/other credits over this decade.

Trends in the three vocational/technical subcurricula

The decrease since 1982 in average vocational/technical credits earned by graduates was due primarily to a decrease in general labor market preparation coursetaking. Furthermore, this decline was due primarily to a decrease between 1982 and 1998 in the number of basic typewriting/keyboarding courses that graduates took in high school. The number of credits that graduates earned in family and consumer sciences education also declined over this period.

In contrast, there were no statistically significant changes between 1982 and 1998 in the average number of credits that graduates earned in occupational education in high school (about 3 credits for each graduating class). There was also no significant change between 1982 and 1998 in the breadth of occupational coursetaking, with most public high school graduates earning at least some occupational credits during the period studied.

Vocational/technical coursetaking by grade level

For the high school graduating class of 1998, the majority of vocational/technical coursetaking (about 60 percent) occurred in the 11th and 12th grades, while about 40 percent occurred in the 9th and 10th grades. Specifically, 1998 graduates earned 1.51 credits on average—the equivalent of about one and a half full-year courses—in the 12th grade. In contrast, 1998 graduates earned 1.01 credits in the 11th grade, 0.75 credits in the 10th grade, and 0.71 credits in the 9th grade.

The timing of occupational and family and consumer sciences education coursetaking was similar to that of overall vocational/technical coursetaking, with more of this coursetaking occurring in grade 12 than in earlier grades. However, general labor market preparation coursetaking was more likely to occur in grade 9.

Trends in occupational coursetaking varied at the different grade levels over the period studied. The average number of occupational credits earned by public high school graduates in the 11th grade decreased between 1982 and 1998, whereas the average number earned in the 9th grade increased. There were no statistically significant changes in the average number of occupational credits earned in the 10th and 12th grades. The reduction in occupational coursetaking in the 11th grade may be related to graduates taking additional academic courses in that grade over the period studied, thereby having less time for occupational coursework.

The average number of occupational credits that 1998 graduates earned in high school was not statistically different from the average number earned by 1982 graduates. However, the percentage of public high school graduates who concentrated in occupational education—those who earned 3.0 or more credits in one of the 10 broad occupational program areas in figure A—declined from 33.7 percent in 1982 to 27.8 percent in 1990. No significant changes were detected after 1990, however, with about 25 percent of 1992, 1994, and 1998 graduates concentrating in occupational education. Trends in occupational coursetaking varied widely by program area, however. The following sections examine program area trends between 1982 and 1998 in the breadth of occupational coursetaking (that is, the percentage of graduates taking at least one course in a program area) and in the depth of occupational coursetaking (including both the average credits earned and the percentage of graduates concentrating in a program area).

Program areas with declining coursetaking

Among the 18 narrow occupational program areas in figure A, the areas of materials production, business management, and mechanics and repair exhibited declines in both the breadth and depth of high school coursetaking over the period studied. For example, materials production exhibited declines between 1982 and 1998 in the percentage of public high school graduates who took at least one course in the program area, in the average number of credits earned by public high school graduates in the program area, and in the percentage of graduates who concentrated (earned 3.0 or more credits) in the program area. Declines in materials production and in mechanics and repair coincided with projected changes in occupational employment in precision production, craft, and repair occupations (Hurst and Hudson 2000).

Paralleling the trends in vocational/technical education and in occupational education noted above, the business services program area exhibited less change in the breadth of coursetaking than in the depth of that coursetaking. There was no statistically significant difference in the percentage of 1982 and 1998 graduates who earned business services credits in high school. In contrast, 1998 graduates earned fewer credits on average in business services than did 1982 graduates, and fewer public high school graduates concentrated (earned 3.0 or more credits) in business services over that period.

Declines between 1982 and 1998 in business services coursetaking were due primarily to declines in average credits earned in non-computer-related business services courses (including bookkeeping, accounting, secretarial, and general office procedures courses). In contrast, average credits earned in computer-related business services courses increased over the same period. Overall declines in business services coursework coincided with projections of below-average growth for secretary and typist occupations (Hurst and Hudson 2000).

Program areas with increasing coursetaking

Two of the 18 narrow occupational program areas in figure A—computer technology and communications technology—generally exhibited increases in both the breadth and depth of coursetaking over the period studied. In addition, both health care programs and child care and education programs exhibited some increase in the depth—but not the breadth—of coursetaking over the period studied. To some extent, these increases in occupational coursetaking reflect projected changes in employment for technicians and related support occupations, health service occupations, and child care workers and teacher aides (Hurst and Hudson 2000).

Between 1982 and 1998, high school students became less likely to concentrate in occupational education. However, the decline in occupational concentrating was not due to changes in the percentage of 1982 and 1998 graduates who earned 3.0 or more occupational credits (who were occupational investors) in high school. Rather, the decline reflected a change in coursetaking among these occupational investors. The percentage of occupational investors who concentrated in occupational education in high school—who earned 3.0 or more credits in one of the 10 broad occupational program areas in figure A—declined from 72.8 percent in 1982 to 59.1 percent in 1992, after which no statistically significant changes were detected.

Additionally, the percentage of public high school graduates who completed an advanced occupational concentration in high school—occupational concentrators who earned at least 1.0 credit in advanced coursework in their program area—declined from 24.0 percent in 1982 to 16.1 percent in 1990, after which no statistically significant changes were detected. Part of this decline in advanced occupational concentrating among graduates was due to the fact that graduates were less likely to concentrate in occupational education in general over the period studied. However, the percentage of occupational concentrators who completed an advanced concentration in their program area also declined from 1982 to 1990, after which no statistically significant changes were detected.

In order to understand changes in coursetaking and concentrating in some detail, the report compared trends among the 18 narrow occupational program areas in figure A.

Shifts away from concentrated occupational coursetaking

What types of occupational courses did occupational investors (graduates who earned 3.0 or more occupational credits in high school) take instead of concentrating in an occupational program area? Some of the decline in the propensity of occupational investors to concentrate in occupational education was due to a shift from concentrating (earning 3.0 or more credits) in business services to taking more communications technology and computer technology courses. That is, occupational investors as a group took fewer business services courses over the period studied (specifically, fewer non-computer-related business services courses)—enough to reduce their concentrating in this program area at a relatively high rate. At the same time, they took additional communications technology and computer technology courses—but not enough to increase their rates of concentrating on a par with their increased coursetaking in these program areas. Thus, the decline in occupational investors' propensity to concentrate in business services coincided with an increase in their total computer-related coursetaking within the occupational education curriculum.

Shifts away from completing an advanced occupational concentration

What types of occupational courses did occupational concentrators take in high school instead of completing advanced coursework in their area of concentration? In part, occupational concentrators took fewer courses in general in their respective areas of concentration between 1982 and 1998. This decrease was due primarily to a decline in second- or higher-level coursetaking, rather than declines in first-level, cooperative education, or specialty courses. As a result of this change, occupational concentrators shifted the distribution of their occupational coursework toward specialty courses. (Typically, specialty courses either offer specialized occupational training or provide related skills that can be applied to a range of occupations and are not part of the usual sequence of courses in a program area.)

About one-third of 1998 public high school graduates took at least some work-based learning courses—defined here as general work experience courses and cooperative education courses—in high school.6 There were no significant differences in either the percentage of 1982 and 1998 graduates taking these courses or the average number of credits these graduates earned in work-based learning courses. Both 1982 and 1998 graduates earned on average about 0.5 credits in work-based learning courses—equivalent to one half-year course.

The report examined changes in participation in vocational/technical education among states that had different changes in high school graduation requirements. Because of limitations in the data, the analysis was restricted to changes between 1990 and 1998.7 Although there were no significant differences between 1990 and 1998 in the percentage of graduates taking vocational/technical courses or in the average number of vocational/technical credits earned by graduates, coursetaking patterns varied somewhat with changes in state graduation requirements over this shortened period.

There was some evidence that, in states that increased their total graduation requirements or their total nonvocational/technical requirements, students decreased their vocational/technical coursetaking. For example, students in states that increased their total high school graduation requirements by 2.0 or more credits between 1990 and 1998 earned on average 1.0 fewer vocational/technical credits by the end of the period. Similarly, students in states that increased their total high school graduation requirements by 2.0 or more credits between 1990 and 1998 were less likely by the end of the period to invest (earn 3.0 or more credits) in vocational/technical education, to invest (earn 3.0 or more credits) in occupational education, or to concentrate (earn 3.0 or more credits) in one of the 10 broad occupational program areas in figure A. In contrast, students in states that increased their total high school graduation requirements by fewer than 2.0 credits, that did not increase these requirements, or that did not have applicable state requirements did not exhibit statistically significant decreases on any of these vocational/technical coursetaking measures.

The SST currently includes all computer-related courses (including those taught in mathematics and computer science departments) under the vocational/technical curriculum. Although some of these courses are classified as general labor market preparation (under basic typewriting/keyboarding and technology education), most computer-related courses are classified as occupational education. These latter courses are included under the business services, computer technology, and drafting/graphics areas.

Computer-related coursetaking in 1998

The 1998 public high school graduates earned on average 1.05 credits in computer-related courses in high school—equivalent to about one full-year computer-related course. Most of these credits were earned in the occupational curriculum, while the rest were earned in general labor market preparation. Within the occupational curriculum, 1998 public high school graduates earned more computer-related credits on average in the business services and the computer technology program areas than in computer-related drafting/graphics courses. Within the general labor market preparation curriculum, 1998 public high school graduates earned more credits in basic typewriting/keyboarding than in technology education.

Within the computer technology program area, 1998 graduates earned more high school credits on average in computer applications courses than in any other computer technology area (including computer science and systems, computer programming, data processing, and computer mathematics).

Computer-related coursetaking from 1990 to 1998

Due to inconsistencies over time in whether basic typewriting/keyboarding courses were classified as computer related (Alt and Bradby 1999), trends in computer-related general labor market preparation courses and in overall computer-related coursetaking were examined from 1990 to 1998. There was no significant difference in the average number of overall computer-related credits earned by 1990 and 1998 graduates or in the average number of computer-related credits they earned within the occupational curriculum. However, comparing 1998 graduates with their 1990 counterparts, there was a decline in the average number of computer-related credits these graduates earned within the general labor market preparation curriculum. This decline was due primarily to graduates taking fewer basic typewriting/keyboarding courses in high school during the 1990s.

In contrast to trends in overall computer-related coursetaking and in computer-related general labor market preparation coursetaking, trends in computer-related occupational coursetaking cover the entire period from 1982 to 1998. Graduates earned on average 0.58 more computer-related occupational credits in high school in 1998 than in 1982, equivalent to more than one additional half-year course. Specifically, 1998 public high school graduates earned on average 0.32 more computer-related credits in business services, compared with 0.20 more credits in computer technology and 0.06 more computer-related credits in drafting/graphics than their 1982 counterparts.

Between 1982 and 1998, public high school graduates increased both the number and rigor of the academic courses they took in high school. On average, 1998 graduates earned 3.98 more credits in academic courses—equivalent to about four full-year academic courses—and they earned more credits in each core academic subject (English, mathematics, science, and social studies) than their 1982 counterparts. The 1998 graduates were also more likely to take advanced coursework in English, mathematics, and science than the 1982 graduates.

Graduates on average decreased their vocational/technical coursetaking by a relatively small amount while taking additional academic coursework over the period studied. In general, students made room for additional academic courses primarily by increasing the total number of credits they earned in high school rather than by reducing their vocational/technical coursetaking. The 1998 public high school graduates earned 0.69 fewer vocational/technical credits on average than the 1982 graduates, while they earned 3.98 more academic credits and 0.25 more enrichment/other credits than their 1982 counterparts (figure C).

Trends in the academic coursetaking of occupational concentrators

Both occupational concentrators and nonconcentrators (the latter including all public high school graduates except occupational concentrators) increased the number and rigor of the academic courses they took between 1982 and 1998. In some instances, the rate of increase was greater for occupational concentrators, possibly because they took fewer and less rigorous academic courses than nonconcentrators at the beginning of the period. Nevertheless, as of 1998, occupational concentrators still took fewer and less rigorous academic courses than nonconcentrators.

For example, although the increase between 1982 and 1998 in mathematics credits earned by occupational concentrators was greater than the corresponding increase for nonconcentrators, occupational concentrators still earned fewer mathematics credits than nonconcentrators at the end of the period. In addition, although both occupational concentrators and nonconcentrators were more likely to take advanced mathematics coursework in 1998 than in 1982, nonconcentrators were more likely than concentrators to do so at the end of the period.

However, as of 1998, coursetaking differences between occupational concentrators and nonconcentrators in English, mathematics, and social studies were fairly small (with differences of less than 0.4 credits on average), and the level of coursetaking for both groups was fairly high (with more than 75 percent meeting the New Basics standards in these subjects8 ), compared with the level of science coursetaking. As of 1998, the gap between occupational concentrators and nonconcentrators in science coursetaking was significantly larger in chemistry than in biology.

Combining college-preparatory and occupational coursework

In keeping with increased academic coursetaking in general, high school students became more likely to complete college-preparatory coursework over the period studied.9 The percentage of public high school graduates completing college-preparatory coursework in high school increased from 8.7 percent for the class of 1982 to 38.9 percent for the class of 1998.

Students also became more likely to combine college-preparatory and occupational coursework over the period studied. Specifically, the percentage of public high school graduates completing both college-preparatory coursework and an occupational concentration in high school increased from 0.6 percent for the class of 1982 to 6.5 percent for the class of 1998. Similarly, the percentage of occupational concentrators who also completed college-preparatory coursework increased from 1.7 percent for 1982 graduates to 25.9 percent for 1998 graduates.

Related academic and occupational coursetaking by program area

The report identified specific mathematics and science courses that were judged to be related to the 18 narrow occupational program areas in figure A. The report then compared the related academic coursetaking rates for concentrators in specific occupational programs with the overall coursetaking rate for 1998 public high school graduates.

Based on this analysis, concentrators in several occupational program areas were found to have taken related academic courses at rates that were below the average rate for all 1998 public high school graduates. In particular, concentrators in construction, mechanics and repair, materials production, food service and hospitality, and personal and other services took all of the identified related academic courses at below-average rates. At the same time, concentrators in communications technology took some of their identified related academic courses at above-average rates.

However, concentrators in most program areas took related academic courses at rates that were not statistically different from the average for all graduates, including concentrators in agriculture, business services, business management, marketing, health care, computer technology, print production, and other precision production.

Footnotes

1 These transcript studies were conducted as part of the High School and Beyond Longitudinal Study of 1980 Sophomores (HS&B-So,1982 graduates), the National Education Longitudinal Study of 1988 (NELS, 1992 graduates), and the High School Transcript Study (HSTS) of 1990, 1994, and 1998 (1990, 1994, and 1998 graduates, respectively).

2 Home economics–related courses that prepare students for the paid labor market are included under occupational education, in the child care and education, food service and hospitality, and personal and other services program areas.

3 In the small number of cases where graduates earned 3.0 or more credits in more than one occupational program area, they were assigned to the program area in which they earned the most credits.

4 The SST divides the occupational courses in each program area into four categories: first-level, second- or higher-level, cooperative education, and specialty courses. The first three categories generally represent sequential coursetaking.

5 Cooperative education awards school credit for work experience that is related to a student's occupational program and typically alternates work placements and classroom time.

6 General work experience awards school credit for work that is not connected to a specific occupational program, while cooperative education awards school credit for work experience that is related to a student's occupational program. This analysis focuses on these types of work-based learning, because they are awarded school credit and recorded on transcripts. In addition, as of 1997, cooperative education was one of the two most common forms of work-based learning in high schools, along with job shadowing (Levesque et al. 2000).

7 It was not possible to link student transcripts to states in the HS&B-So data set, which provided information on 1982 high school graduates for this report, and data on state graduation requirements were not available for 1992 and 1994.

8 The New Basics core academic standards include 4 years of English and 3 years each of mathematics, science, and social studies (National Commission on Excellence in Education 1983).

9 College-preparatory coursework is defined as earning 4.0 or more credits in English; 3.0 or more credits in mathematics at the Algebra 1 or higher level; 2.0 or more credits in biology, chemistry, or physics; 2.0 or more credits in social studies with at least 1.0 credit in U.S. or world history; and 2.0 or more credits in a single foreign language.
