In 2008, the U.S. Department of Education awarded a contract to a team of education, youth development, and web development specialists to develop an online professional learning community for grantees in the 21st Century Community Learning Centers (21st CCLC). The online community, You for Youth (Y4Y, www.Y4Y.ed.gov) will support afterschool practitioners' professional development, encourage their discussion and reflection, and support positive change in their professional practice. During the first year of the contract, the team assessed the professional development needs of the 21st CCLC community. Using this input, a prototype for a user-centered web portal and learning community, was designed which includes multimedia learning modules in several topic areas. The result will be an efficient system for delivering professional development based on the expressed needs of the afterschool community.
