See Sacramento high schools with the best AP test scores

By Phillip Reese - preese@sacbee.com

Students in the four-county region scored well enough on 17,845 Advanced Placement tests to earn college credit last school year, up 60 percent from five years prior, according to new data from the California Department of Education.

Advanced Placement classes are designed to be equivalent to college-level instruction. Most colleges allow students who score well on an end-of-course AP exam to earn college credit and skip that class when they arrive on campus.

Many schools across the region and state have recently increased their Advanced Placement classes - and far more students are taking advantage.

But there are huge gaps in Advanced Placement offerings and credit-eligible AP scores between high schools in the region. Schools with a high number of economically disadvantaged students tend to also have fewer pupils taking and scoring well on AP exams.

AP exams are scored from 1 (worst) to 5 (best). A score of 3 is generally good enough to earn college credit. This map shows the number of scores 3 and above per 100 11th- and 12th grade students at each school in the region during 2013-14.
