U.S. Senator Al Franken says next year’s re-writing of the No Child Left Behind education law should include more money to train school principals, Minnesota Public Radio reports. The DFL-er has introduced legislation that would establish federal grants to pay for an apprentice program that places aspiring or current principals in high-need schools. “The effectiveness of principals in high-risk or high-need schools is one of the primary determinants of whether these schools are able to attract and retain effective teachers,” he said, in an interview. Franken’s bill doesn’t specify how much money would be spent on the training, but he argues federal money should be used because states don’t typically fund these kinds of programs.
