Middle College, a high school program on the LaGuardia Community College campus, was designed to reduce the urban dropout rate, to prepare students more effectively for work or college, and to attract more students to higher education. As a public alternative high school on a college campus, the program creates a continuum between high school and college, featuring flexible pacing, broad curriculum options, service-oriented career education with required internships for all students, and a college environment. The school opened in 1974, with 125 students in the 10th grade. Each year, 125 more students were added after local junior high schools identified them as probable dropouts. This report on Middle College focuses on: (1) background information on the establishment of the program; (2) Middle School's service to the joint missions of the community college and the high school; (3) the Cooperative Education Program; (3) curriculum and the organization of high school and college course options; (4) problems that have been encountered and the way these problems were resolved; and (5) keys to the success of the Middle College program (e.g., the assumption of adulthood and respect for personal decisions of students, emphasis on awareness of personal options and control, and the power of the college environment). Finally, suggestions for the development of similar programs are offered, including early admission of the academically able student, cooperation between college and high school faculties, and institutional restructuring.
