The program responds to current concerns and projections about shortages of STEM professionals and information technology workers in the United States/place>/country-region> and seeks solutions to help ensure the breadth and depth of the STEM workforce. ITEST supports the development, implementation, testing and scale-up of models, as well as research studies to address these questions and to find solutions. There are a variety of possible approaches to improving the STEM workforce and to building students’ capacity to participate in it. NSF seeks to expand the existing ITEST portfolio by addressing students at any age for grades kindergarten through high school and by including all areas of the STEM workforce, while retaining an emphasis on technology-related areas. A letter of intent is due Feb. 15, 2008. The full proposal deadline is April 10, 2008.
