The Sanger Independent School District (SISD) is an independent government body. However, the City of Sanger considers SISD an integral partner and works closely with SISD on matters of mutual interest. SISD has made major investments in new buildings and facilities. These new facilities include a new high school complex and a new state of the art elementary school. SISD has positioned itself well for the future and is known throughout the area as a progressive school system committed to providing a quality education to its students.
