Missing values indicate a test was not available in a given year.
Scores shown are averages based on the performance of graduating seniors in each of the years shown. Averages typically do not equal 500 because each year's scores are based on a cumulative reference group made up of the previous six years' graduates. The composition and performance of the reference groups differ somewhat from year to year.
