ITEST Learning Resource Center
http://www2.edc.org/itestlrc/
The Information Technology Experiences for Students and Teachers (ITEST) program was established by the National Science Foundation in direct response to the concern about shortages of information technology workers in the United States.
ITEST funds opportunities for both school-age children and teachers to build the skills and knowledge needed to function and contribute in a technologically rich society. Explore projects by content areas, such as computer science and engineering; by types, such as comprehensive and youth-based; by the target areas of urban, suburban, and rural; and by region of the United States.
ITEST also funds a National Learning Resource Center to support, synthesize and disseminate the learning from the program to a wider audience.
