Information collected from the public school districts of Colorado was used to prepare the tables of this report and the accompanying introduction, which summarizes trends in pupil membership. In the fall of 1992, there were 612,635 students in Colorado public schools. This was the third year of substantial increase in enrollment, and was the largest total in Colorado history. Elementary school pupil membership increased by 2.9 percent over 1991 and by 25.3 percent over 1983, and secondary school student membership increased by 3.8 percent over 1991 and declined by 7.7 percent from 1983 to 1989. Between 1983 and 1992, minority enrollment increased by 30.2 percent, with minority groups representing 25.5 percent of the fall student membership. The largest school districts grew larger, and accounted for 55.1 percent of the total state growth in membership. Denver metropolitan area schools include 53.9 percent of the total state enrollment. The 1992 student/teacher ratio of 18.3 to 1 reflected the increase in student population. The graduation rate for 1992 of 79.9 percent was larger than that of 1991 by 1.0 percentage point. Nine tables present data on student enrollment and characteristics. (SLD)
