The California Community Colleges (CCC) has implemented a prototype model for determining student transfer readiness as a primary means of assessing community college transfer effectiveness. This report provides definitions of transfer readiness and guidelines for colleges participating in the CCC transfer readiness study. First, a memorandum from the CCC Chancellor's Office is presented introducing the transfer readiness pilot study and providing a list of 19 participating colleges, with institutional contacts. Next, transfer readiness is defined as the number of students who complete transfer eligibility requirements divided by the number of transfer-directed students in a given time frame and a rationale for studying transfer readiness is presented, suggesting that it measures institutional effectiveness rather than intersegmental effectiveness measured by the transfer rate. The next section highlights the problem of including students with no intentions of transferring to four-year colleges in the traditional transfer rate and provides recommendations for implementing the transfer readiness measure and a completed transfer readiness pilot study worksheet for the fall 1991 cohort. A memorandum from the American River College, a pilot study participant, describing procedures for calculating the transfer ready values, reviewing steps for processing data, and including sample transfer ready worksheets, is appended.
