Preparatory Academy has a powerful group of counselors, social workers and diagnostics to support our students on the daily.

They invest their time in seeing that our students excel in-and-out of the classroom, by providing mentoring opportunities, and seeing through that students are getting the academic assistance needed to tackle STISD's challenging course curriculum.
