Md. Leads U.S. in Passing Rates on AP Exams - washingtonpost.com: ...Six states, including Maryland and Virginia, had at least one-fifth of graduates pass an AP test in high school: New York (23.3 percent), Connecticut (21 percent), Massachusetts (20.8 percent) and California (20.2 percent). The nationwide rate for the Class of 2008 was 15.2 percent. In the District, the rate was 6.9 percent. All figures represent only public schools.
About 10 percent of graduates nationwide who took one or more AP tests never attained a passing score. The same was true for about 13 percent of 2008 graduates in Virginia, 14 percent in Maryland and 19 percent in the District.
Virginia and Maryland have ascended in the AP program, with their largest systems leading the way. In Montgomery County, 46.4 percent of last year's graduates passed one or more AP tests, twice the state average and three times the national average. Fairfax County did not release such figures, but the system ranked just above Montgomery in the latest edition of the Challenge Index.
