This report is the seventh in a series of longitudinal studies describing the College Discovery and Development Program aimed at identifying disadvantaged and underachieving ninth graders and developing their college potential in five special high school development centers. The document has an introductory section including such topics as the seventh year of the progra, the setting, staff, student personnel, and fiscal matters. Other sections include a description of the seventh population of college discovery students, attendance and achievement for all classes in 1971-1972, college progress of program students in Classes I-IV, high school graduation and admission to college for class V, a socioeconomic overview of Classes I-VII, a description of an adjunct summer program in mathematics, and summary. Class VII resembled the previous six groups in age, family structure, living conditions, ethnicity, history of mobility, previous scholastic averages, and attendances, but was found to be less well off economically than other classes. The general findings for program students whose college records can be studied show a pattern of progress not greatly different from than of nonprogram classmates in each college. (Author/AM)
