The Insider has learned that Proviso High School District 209 dropped 235 students in the past year after a hired outside investigations firm provided information that those students did not live in the district.
Because of that success, District 209 officials are finalizing contract negotiations to continue working with National Investigations Inc.
National Investigations identified the 235 non-resident students between March 2007 and Feb. 29, 2008.
Proviso West had 144 students dropped, while 85 were dropped at Proviso East, and six were dropped from Proviso Mathematics and Science Academy. Among its three schools, District 209's enrollment is approximately 5,000 students.
The dropping of non-resident students can save the district thousands of dollars in per pupil expenses. District officials can also seek repayment of tuition from all of those students who violated residency requirements.
