About the Data

Because a central source of demographic data for nonpublic schools is not available for all states, this report represents public school students only. References to the total number of high school graduates represent projections supplied in Knocking at the College Door (Western Interstate Commission for Higher Education, 2008).

Additionally, this report looks at students’ entire experience with AP — tracking exams taken by graduates throughout their high school careers — as opposed to just reporting exam results from a particular calendar year.
