Preparation of math teachers

The National Council on Teacher Quality has released a report about preparation of math teachers in the US. Here is a copy from the press release:
No Common Denominator: The Preparation of Elementary Teachers in Mathematics by America's Education Schools, June 2008
American students' chronically poor performance in mathematics on international tests may begin in the earliest grades, handicapped by the weak knowledge of mathematics of their own elementary teachers. NCTQ looks at the quality of preparation provided by a representative sampling of institutions in nearly every state. We also provide a test developed by leading mathematicians which assesses for the knowledge that elementary teachers should acquire during their preparation. Imagine the implications of an elementary teaching force being able to pass this test.
On the web site of NCTQ, you can download an executive summary, the test and answer key, or the full report.
