The Improving Teacher Quality Program recently concluded its 2007 competition to select grantees who will provide high-quality teacher professional development over the next several years. Teachers in grades K-2 were the focus of this year's Request for Proposals (RFP). As required in the last two rounds of competition, the selected projects must also conduct rigorous evaluation research on their results. Most of the new projects awarded in 2007 are in the subjects of science and mathematics, showing a great need for professional development in these core content areas. This report summarizes each of the new grants that began work in late autumn.
