Scores are averages based on the performance of graduating seniors in each of the years shown.  Average scores 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.

*The 2019-20 averages include only tests taken between June 1 and December 31, 2019 because of disruptions in testing and shifts to unsupervised testing due to COVID-19.

** Annual averages are not available for these areas due to insufficient sample size.

Beginning with 2018-19, standard deviations are included in parentheses.
