In April 2006, the Consortium on Chicago School Research (CCSR) released a report on college enrollment, preparation, and completion by students in the Chicago Public Schools (CPS). This was the first endeavor in the nation to use data from the National Student Clearinghouse (NSC) to track the progress of a large district's students following their high school graduation. College graduation rates of CPS alumni who completed high school in 1998 and 1999 were reported. Using the updated data, the overall college graduation rate for CPS alumni increases from 35 percent to 45 percent. This is primarily due to the revised graduation rate for Urbana, although other factors also contribute to the increase, including: (1) small increases in the graduation rates at other schools with updated student records; (2) the removal of Carbondale from these statistics; and (3) the participation of several additional colleges in the NSC, including DePaul University which has a graduation rate of 76 percent. The aggregate statistic of the percentage of students who begin high school in CPS and earn a four-year college degree by their mid-twenties increases just slightly--from 6 to 8 percent. Even with the revised data, the six colleges most attended by CPS alumni still show graduation rates that are below average. Only 41 percent of students at the most popular four-year institutions graduated within six years, compared to 49 percent of in-state students at less popular institutions, and 56 percent of students who chose out-of-state colleges.
