New Data on AP's Impact

Jay Matthews:

On one wall of my cubicle is a large chart extracted from Tom Luce and Lee Thompson's 2005 book "Do What Works: How Proven Practices Can Improve America's Public Schools." It shows that a study of 78,000 Texas students found college graduation rates much higher for those who, while in high school, took Advanced Placement exams -- but failed them -- than those who took no AP exams at all.

At this point, you may be saying, "Huh?" We AP wonks are an odd breed. We often cite statistics that make no sense to normal people. But I will try to explain this one, and why it was greeted with such excitement by AP teachers four years ago.

AP courses are given in nearly 40 subjects. They allow high school students to earn college credit, or at least skip college introductory courses, if they do well on the final exams. Many AP teachers argue that students' grades on the three-hour exams, given in most U.S. high schools every May, are not as important as taking the college-level course and exam and getting a taste of college trauma. Many of their students who flunk the AP exam still report, when they come back to visit after their freshman year of college, that the AP experience made it easier for them to adjust to fat college reading lists and long, analytical college exams. They may have failed the AP exam, but by taking it, and the course, they were better prepared for the load of stuff dumped on them in college. When they took the college introductory course in the subject that had been so difficult for them in high school AP, they did much better.

The Texas study showing that failed AP students were more likely to graduate from college than non-AP students was thus greeted as proof that the AP teachers' view on this issue was correct. But the researchers who had done the work cautioned against putting too much weight on it. There were too many variables to reach hard conclusions.

More from Matthews:

On pages 35 and 36 of their report, the Texas researchers revealed what was for me the most interesting of their many new disclosures. They show that even students who only get a 2 on their AP exams after taking the AP course have significantly better college outcomes than non-AP students. Students who get 1s on the exam do not do better than non-AP students, but as I have often heard AP teachers say, they have no chance to build those students up to a 2 or a 3 unless they are allowed in their courses.

These are complicated issues. This study is not the last word. Critics of AP may say that these researchers' work is tainted by the fact that the College Board, which owns the AP program, paid them for their study. But there is no question they are reputable, independent scholars, and their data is there for all to see.
