About this Indicator
The percentage of students in grade 8 scoring at or above proficiency on the National Assessment of Educational Progress (NAEP) provides a measure of whether students enter high school with foundational skills and knowledge in such areas as math, reading, and science. Eighth grade academic achievement has been found to be a highly significant predictor of college readiness among 12th grade students.
