In 1989, microeconomics and macroeconomics examinations debuted on the Advanced Placement (AP) scene. At that time, many professors of economics were skeptical that college freshmen had the skills and maturity to understand the concepts in principles of economics courses. They thought teaching these concepts to high school students was even more ridiculous. Nevertheless, 5,781 microeconomics and macroeconomics tests were administered in the initial year. In 2007, 97,499 microeconomics and macroeconomics exams were administered, a nearly 17-fold increase in less than 20 years. AP economics had arrived as a high school subject. Has AP economics lived up to its expectations? Does it raise standards while still providing equity in education? The authors think the answer to both of these questions is a resounding "yes." In this article, the authors discuss how AP economics prepares students for college, provides feedback on school success, and saves students money. (Contains 9 notes.)
