This schedule establishes mandatory minimum retention periods for records that are associated with Public School Districts. No local government office may dispose of a record listed in this schedule prior to the expiration of its retention period. A records control schedule of a local government may not set a retention period that is less than that established for the record in this schedule. Original paper records may be disposed of prior to the expiration of their minimum retention periods if they have been microfilmed or electronically stored pursuant to the provisions of the Local Government Code, Chapter 204 or Chapter 205, as applicable, and rules of the Texas State Library and Archives Commission adopted under those chapters. Actual disposal of such records by a local government is subject to the policies and procedures of its records management program.
