STISD is consistently ranked among the best in the state and nation.

STISD is the only all-magnet school district in the state, and offers Valley students an educational alternative. The district provides a personal environment, a strong scholastic program and hands-on training in vocational career fields.

Because STISD is a public school district, there is no cost for students to attend one of its seven campuses, and bus transportation is also free of charge.

STISD schools maintain an open enrollment policy, meaning any student that wants to attend one of our seven campuses can as long as he or she resides within the tri-county area we serve.

At STISD, meet curious, collaborative and driven students just like you.

At STISD, there's more to experience than solely academics. Explore what life is like as an STISD student, and be part of the many extracurricular competitive activities and social clubs.
