From fall 1990 to fall 1994, Florida's Miami-Dade Community College (M-DCC) experienced a decline in enrollment among first-time-in-college students. To determine reasons for the decline, M-DCC examined characteristics and high school of origin of first-time students in the period, categorizing students as direct-entry (i.e., entering within 1 year after high school) and delayed-entry (entering more than 1 year after high school). The analysis revealed a decline in first-time students of 1,283, or 14%, over the period, with direct-entry students declining by 622 and delayed-entry by 661. Moreover, enrollment among students from non-Dade County high schools accounted for 69.8% of the total loss. Based on these data and reviews of external circumstances, the enrollment loss was found to be associated with the following 3 events: (1) an increase in tuition and fees between fall 1990 and fall 1991; (2) the combined effects of the tuition and fee increases and Hurricane Andrew between fall 1991 and fall 1993; and (3) a policy change by Florida International University to lower admission standards, resulting in another loss between fall 1993 and fall 1994. Finally, while tuition and fee increases resulted in a decrease in enrollment and credits for all categories of first-time students, total revenues from tuition and fees increased over the period for Florida residents but decreased for out-of-state and out-of-country residents.
