Nor Cal Phase III was the experimental portion of the 3-year attrition study. The general purpose of the study was to design and test treatments aimed at reducing attrition among first-time freshmen entering community colleges. Twenty-eight colleges (22 in Northern California, five in Southern California and one out-of-state) were involved in either conducting a Phase III study or in further validating the Nor Cal questionnaire. Plans to develop research projects at each of the participating campuses were hampered by limited resources and lead time. Twelve colleges found time and staff to conduct true experiments with defineable treatment variables; seven other colleges conducted post hoc or quasi-experimental studies; and nine colleges further validated the Nor Cal instrument. Reports from these individual projects are included. (AL)
