State Board of Education Meeting Sept. 9-10: View Agenda | Watch LIVE
Pupil Count

Summary
Each year all public school districts in Colorado participate in the Student October Count data submission. CDE’s Information Management Services (IMS) unit oversees the collection through Data Pipeline. The data from Student October is used to calculate the total program funding each school district receives. The legislature sets the public school total program funding formula under the Public School Finance Act (C.R.S. 22-54-101).
The Funded Pupil Count is part of the funding formula. This is the number of students who meet the membership and scheduling requirements as of the count date. For full details, check out the Audit Resource Guide below!

Personally Identifiable Information (PII) Disclaimer

Some forms recommended by the School Auditing Office may contain personally identifiable information of students and districts should take additional precautions. Local education agencies must use secure means when sending Personally Identifiable Information (PII) to CDE. If transferring PII between districts, schools, or with other parties, CDE strongly recommends that districts use a secure method of transferring PII between districts, schools, or with other parties (for example, a secure file sharing tool like Syncplicity, or including the PII in a password-protected document).
