This is the 25th annual report of data on the distribution of minority group students in the public schools of Connecticut for the fall of 1990, and the 23rd to report data on minority staff members. The data, collected under a legislative mandate, are used to monitor any possible imbalance of white and minority students in the public schools. In October 1990, minority students totaled 25.1 percent (117,155) of Connecticut public school students statewide (466,664), continuing the trend toward increasing minority representation in spite of a decline in total enrollment. The number of Hispanic American students grew more rapidly than that of other ethnic groups. In Connecticut's five largest cities, 77.3 percent of all students were members of minority groups, and minority students were 92.1 percent of the total enrollment in Hartford. Thirteen public schools (1.3 percent) are technically out of compliance with state racial imbalance regulations. Of the total full-time professional staff, 6.3 percent (2,453) are minorities. Statistical data are provided in 5 tables and 10 figures. Ten appendixes present additional data tables about staff and enrollment. (SLD)
