| 2 The percentile represents a specific point on the percentage distribution of all students ranked by their reading score from low to high. For example, 10 percent of students scored at or below the 10th percentile score, while 90 percent of students scored above it. | ||||||||||||||||||||||||||
| 3 The standard deviation provides an indication of how much the test scores varied. The lower the standard deviation, the closer the scores were clustered around the average score. About two-thirds of the student scores can be expected to fall within the range of one standard deviation above and one standard deviation below the average score. For example, the average score for all 4th-graders was 221, and the standard deviation was 35. This means that we would expect about two-thirds of the students to have scores between 256 (one standard deviation above the average) and 186 (one standard deviation below). Standard errors also must be taken into account when making comparisons of these ranges. For a discussion of standard errors, see Appendix A: Guide to Sources. | ||||||||||||||||||||||||||
| NOTE: Scale ranges from 0 to 500. Includes public and private schools. Excludes persons not enrolled in school and those who were unable to be tested due to limited proficiency in English or due to a disability. Race categories exclude persons of Hispanic ethnicity. Standard errors appear in parentheses. | ||||||||||||||||||||||||||
