TechSIS (Texas Tech Student Information System) was a mainframe computer system which served as the primary data storage system for all student data at Texas Tech University and the Texas Tech University Health Sciences Center.

In the Spring semester of 2009, the Banner database replaced TechSIS as the primary data store. Some TechSIS data was migrated to Banner. Data not available in Banner may be available through other reporting mechanisms. Contact IT Help Central for additional information.
