ACAT Business was first administered in 2006-07. The 2011-12 administration year was the first in which a full 6-year reference group was available. 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 (2012-2024) to ten (2025+) years' graduates. The composition and performance of the reference groups differ somewhat from year to year. Scores not listed (---) did not meet the minimum requirements for sample size.
Beginning with 2018-19, standard deviations are included in parentheses. * Annual averages are not available for 2019-20 due to the effect of COVID-19 on sample sizes and the restriction of the available data to Summer/Fall 2019. |
