Data Pipeline Interchanges - Teacher/Student Data Link


The Teacher Student Data Link Interchange (TSDL) file is minimized from 3 previous files (Statewide Standard Course Codes, Course Instructor and Course Enrollment files) into one file.   The TSDL file captures data that link students in grades 6 through 12 to courses and instructors (if available) for the reported school year. CDE relies on the TSDL data for the following reporting requirements: student course participation and achievement report, migrant student tracking/reporting, educator preparation program outcomes, and prepopulating the Office of Civil Rights (OCR) report.
