Originally planned to open in the fall of 1965 under funding from the Office of Economic Opportunity, and continued over the years with State Act for Disadvantaged Children funds, Higher Horizons 100 (HH100) was from its inception conceived as a ninth grade center where a compensatory program would work. Despite its expansion from one team to a present total of four high school and four middle school teams, HH100 as a program continued to provide articulated services geared toward skill remediation, guidance services, and cultural exploration and these to groups of approximately 100 urban youngsters in each of the program's eight centers. While the cultural activity funds were necessarily limited, team members were still able to provide youngsters with a number of vocational, experiential, and career services as these were contemplated in the original and in subsequent proposals. As a model for secondary school compensatory education, the original format was set up to enable the HH team to plan activities and programs in conjunction with the students. Through a series of systematic formal and informal planning sessions, team members would receive continual participant feedback and could use this information as a basis for modifying the program so as to better individually diagnose needs and prescribe appropriate educational treatments.
