Data Pipeline Snapshots: Teacher Student Data Link

Overview

The purpose of the Teacher Student Data Link Snapshot (TSDL) is to capture the data from the TSDL interchange file which links the students to courses and instructors (if available) for the reported school year. CDE relies on the TSDL snapshot data to populate and to create the Student Course Participation and Achievement Report (as required by C.R.S. 22-11-503.5) as well as to complete required reporting for migrant students. Other CDE reports, such as for: Educator Effectiveness, Federal Programs, and the Office of Civil Rights rely on accurate data.
