! Interpret data with caution. The coefficient of variation (CV) for this estimate is between 30 percent and 50 percent (i.e., the standard error is at least 30 percent and less than 50 percent of the estimate).
‡ Reporting standards not met. The coefficient of variation (CV) for this estimate is 50 percent or greater (i.e., the standard error is 50 percent or more of the estimate) or the response rate is below 50 percent.
NOTE: Includes public school teachers who taught departmentalized or single-subject classes to students in any of grades 5–8 and no grade lower than 5 or higher than 9, and whose main teaching assignment was mathematics or computer science. Degrees in main assignment are defined as bachelor's level or higher with a first or second major in mathematics, computer science, engineering, or physics. Degrees awarded within or outside of schools/colleges of education are included. Teaching certificates that meet the following criteria are defined as being in field: (1) regular or standard certificate, advanced professional certificate, or probationary certificate issued or recognized by the state; (2) applies to at least one of grades 6–8; and (3) applies to at least one content area of mathematics, computer science, or physics. Detail may not sum to totals because of rounding.
