This document describes the analytic process undertaken by staff of the Research & Planning Unit in the Technology, Research, and Information Services Division of the Chancellor's Office of the California Community Colleges to identify persistently low transfer colleges within the system, as mandated by the State Legislature in 2002. This document contains new data made available after the Report to the Legislature, March 1, 2002. First-time freshmen in the fall cohorts of 1993, 1994, and 1995 were tracked for 6 years to identify those exhibiting course-taking behavior consistent with intent to transfer. The colleges in each cohort year were ordered according to the magnitude of each college's residual. A simple and robust measure of an extreme value in a distribution of numbers was selected: the interquartile range (IQR), which is the numeric distance between the 25th and 75th percentiles. The IQR for the residuals of each cohort year were calculated and then used to calculate the distance of each observation in each cohort year from the nearest outer edge of the middle 50% of observations. This statistical effort to adjust transfer rates effectively accounted for variation in the systematic, uncontrollable factors of transfer performance among the community colleges. (NB)
