Community colleges across the country will receive about $500-million in federal grants beginning on Monday, the first of four payments in a $2-billion plan announced last year that is intended to improve career-development programs and train an ailing work force. More than 200 community colleges applied for the grants, which range from about $2.7-million to $25-million, but only 49 have been chosen to receive the money so far, officials from the U.S. Departments of Labor and of Education said in announcing the awards. Community colleges in 15 states, the District of Columbia, and Puerto Rico did not receive grants, but will work with the federal departments to develop programs that are eligible—each will receive about $2.7-million. The winning colleges will be able to buy equipment, hire staff members, and develop job-training curricula.
