Senate Bill 19-129, concerning the regulation of online schools, calls for the Colorado Department of Education's Office of Blended and Online Learning to produce an annual report on the number of students who withdraw from Colorado K-12 online schools after the pupil enrollment count date. This report is required to include the dates on which students withdrew from enrollment, the grade level at which the students were enrolled at the beginning of the school year, the grade levels at which the students were enrolled when the students transferred, and information on whether the students enrolled in another public or private school or home-based education (home school) setting or graduated or completed high school within the same year. Based on an analysis of the 2019-20 data for students enrolled in both types of online schools, the three most widely assigned exit codes were for: (1) students withdrawing and transferring to a school in another school district (n=1,079); (2) students dropping out (n=1,004); and (3) students transferring to a nonpublic home-based education setting (home school) (n=580). The data from 2018-19 compared to data from the 2019-20 year showed a decrease of 273 student withdrawals. Students coded as completing and not exiting at any time during the school year increased by 848 students from the previous year. [For the 2020 report, see ED610711.]
