Kenneth Bernstein, via Valerie Strauss:

You are a college professor.
I have just retired as a high school teacher.
I have some bad news for you. In case you do not already see what is happening, I want to warn you of what to expect from the students who will be arriving in your classroom, even if you teach in a highly selective institution.
No Child Left Behind went into effect for the 2002-03 academic year, which means that America’s public schools have been operating under the pressures and constrictions imposed by that law for a decade. Since the testing requirements were imposed beginning in third grade, the students arriving in your institution have been subject to the full extent of the law’s requirements. While it is true that the U.S. Department of Education is now issuing waivers on some of the provisions of the law to certain states, those states must agree to other provisions that will have as deleterious an effect on real student learning as did No Child Left Behind–we have already seen that in public schools, most notably in high schools.
……
I mentioned that at least half my students were in AP classes. The explosive growth of these classes, driven in part by high school rankings like the yearly Challenge Index created by Jay Mathews of The Washington Post, is also responsible for some of the problems you will encounter with students entering your institutions. The College Board did recognize that not everything being labeled as AP met the standards of a college-level course, so it required teachers to submit syllabi for approval to ensure a minimal degree of rigor, at least on paper. But many of the courses still focus on the AP exam, and that focus can be as detrimental to learning as the kinds of tests imposed under No Child Left Behind.
Let me use as an example my own AP course, U.S. Government and Politics. I served several times as a reader for the examination that follows the course. In that capacity, I read the constructed responses that make up half of the score of a student’s examination. I saw several problems.
