In my experience with STISD has been great! All teachers and students are helpful, they do their best to help you with your classes and decisions. The teachers are very aware of their students grades along with how the student are personally. Administration helps with any questions you have and help you with your decisions for after High school. I've met with amazing people in this school that have helped me throughout my high school experience! This is an amazing school?

South Texas Independent School District is amazing when it comes to providing transportation to those living all over the Rio Grande Valley, not only in the morning and after school, but also to those who stay for afternoon tutoring. The district also provides variety of highschools from the the spectrum of business, engineering, and medicine! Its been a pleasure of being part of this district for the past 4 years.
South Texas ISD has a variety of campuses located in the Rio Grande Valley of Texas. Each high school offers different pathways into your future career. I attended a middle school that they had just opened and I really did not know what to expect because I have never been offered an opportunity this valuable. It changed me into a strong, reliable, and responsible student and motivated me to achieve the impossible. They prepared me for my future classes while also working really hard and maintaining a young adult life. I moved on to high school ready to achieve. Since i’ve been with the district I have had no problems and they are always their for you no matter what circumstance.
