An evaluation was done of the Queens Tri-School Confederation, three high schools in the New York City Public Schools funded by a federal grant from the Magnet Schools Assistance Program. The grant provided Hillcrest, Jamaica, and Thomas A. Edison High Schools with funds to develop or expand emergency technician programs at Hillcrest; a law program at Jamaica; and medical/pharmaceutical and emergency medical vehicle maintenance programs at Edison. The programs were implemented in the 1991-92 year and include new courses, particularly laboratory courses with corresponding written curricula that emphasized higher-level thinking skills. Efforts were made to recruit students, particularly from among white populations. This resulted in an increase of about three percent in incoming ninth grade non-minority populations at Hillcrest and Edison. Jamaica still showed a downward trend. Programs to reduce minority group isolation included a multicultural club, peer mediation, a program to train student leaders in inter-ethnic relations, and increased community service. Test scores and attendance improved at all schools. Student ratings of program aspects were disappointing and atmosphere and safety were areas of concern. Twelve tables are included. (JB)
