A sad attack on Advanced Placement

Jay Matthews:

Nearly all of us are experts about something — Yorkshire terriers, Redskins quarterbacks, California native plants, whatever. Even obscure subjects have fans.
My obsession is the Advanced Placement program, those college-level courses and tests for high school students. I have studied AP for 30 years. I am saddened, as all devotees are, by outbursts of misinformation about my topic. The most recent example is an essay on TheAtlantic.com by former AP government and politics teacher John Tierney, entitled “AP Classes Are a Scam.”
