A student flow model is presented to raise the awareness of administrators and community leaders regarding the impact of proposed testing requirements in the state of Florida; i.e., the addition of a State Student Assessment Test (SSAT) of functional literacy, a statewide college entry level test, and the College Level Academic Skills Test (CLAST) required for passage to the junior year. The model presents data depicting the current testing systems and changes in student flow engendered by the new testing requirements. Table 1 presents the hypothetical flow for a typical sample of 100 high school graduates who attempt to register at Miami-Dade Community College (M-DCC). For Black, White, and Hispanic students, this table presents the number of students who, with the testing requirements and without them, would leave Dade County public schools before graduation; write the SSAT, Part II; fail the SSAT; graduate from high school; score below the 15th percentile on one or more statewide placement tests and be excluded from M-DCC enrollment; register at M-DCC; remain enrolled for 1 year; complete courses required for an associate degree; score below -1 standard deviation on one or more CLAST subtests; and graduate from M-DCC. Table 2 presents student flow in these areas using actual headcount numbers to provide a sense of the magnitude of the impact of the testing requirements. A discussion of the data elements and tests is included. (HB)
