Collection Freeze Dates: Districts are required to submit student-level data for the October, and June collections. The Freeze Date (F1) will be used for mandated Federal, State and public reporting while the Freeze Date (F2) will serve as the last possible date for corrections to that collection. It should be noted that additional internal freeze dates (F0) of the October collection will be used for various internal reporting and grant calculation purposes. Districts should work diligently to submit accurate data and make all corrections prior to the applicable freeze dates. After the ‘freeze date’ has passed, changes to data will not be permitted. PSIS data is frequently used for public analysis, reporting and publishing; in cases where a district provides incorrect data in a collection submission and the data is not corrected prior to the applicable freeze date, it will be reported as is. LEAs are strongly encouraged to ensure they have provided accurate data to CSDE prior to certifying the active collection. Please contact the appropriate collection manager with questions.
