This article reports the findings of the first audit of Advanced Placement (AP) courses. One of the more striking effects of the audit, the results of which were released recently by the College Board, was a steep drop in the number of schools offering Advanced Placement courses. After more than 30 years of steady growth, the number of schools worldwide offering at least one AP course dropped by nearly 13 percent from the 2006-2007 school year to the current one, according to the College Board, the New York City-based nonprofit organization that owns the Advanced Placement brand. The decrease in the number of schools offering AP classes comes amid efforts by the College Board, President Bush, and others in the policymaking and education arenas to dramatically expand access to AP courses among groups of students who are underrepresented in them, including those from low-income families and some racial- and ethnic-minority groups.
