To find out which NISD Trustee district you live in, go to the Bexar County Precinct Finder and enter your street name. Follow the prompts, and once the elected official information for your address is pulled up, scroll down and look for "School District." (Residents of Bandera and Medina counties who live in Northside ISD are located in Trustee District 7.)
