Should We Inflate Advanced Placement (AP) Grades?

Jay Matthews:

The Rochester, N.Y., public schools do a fine job. Their leaders often have great ideas. But according to Rochester school board member Mike Reno, they are talking about doing something to their Advanced Placement courses that could be troublesome, even though I once thought it was a good idea. (Some people who know me say that is the very definition of a bad idea.)
Here is what Reno revealed in an email to me:
“Our district, in an effort to increase AP participation, is proposing to lower the grading scale for AP classes. The idea is based on the notion that kids in Rochester don’t want to take AP classes because they are afraid that the tougher work will lead to a lower grade, and they don’t want to damage their GPA for fear it will harm their college entrance chances. The district’s logic suggests by that lowering the grading scale, students will have a better chance of getting a better grade, and therefore be more willing to take the class.
“This is not their brainchild. They claim other districts are doing it. They are calling it internal weighting. They believe this is a better approach than grade weighting, where an A in an AP class would be worth, say, 5.0 instead of 4.0. The district argues that colleges strip off weighted grades, whereas an internal weight benefits the student during college entrance. (I believe grade weighting has value when calculating class ranking, vals, sals, top scholars, etc, but think colleges are free to recalculate anything they’d like). Am a crazy to think this is a bunch of nonsense?”
