The GreatSchools Rating helps parents compare schools within a state based on a variety of school quality indicators and provides a helpful picture of how effectively each school serves all of its students. Ratings are on a scale of 1 (below average) to 10 (above average) and can include test scores, college readiness, academic progress, advanced courses, equity, discipline and attendance data. We also advise parents to visit schools, consider other information on school performance and programs, and consider family needs as part of the school selection process.

All administrators do everything possible in order for the students to be successful. They keep the parents informed at all times and have complete transparency.

The parking lot can be a big safety issue before and after school, but having open campus lets students go get lunch near by. School spirit can be better but we need to win more sports games.

The best part about O'Connor is it allows students the opportunity to explore multiple career fields. They have classes for various fields so you can see if you like it. There isn't a limit on what you can do. There are multiple arts, sports, and STEM activities that you can participate in. For example, I will take Forensic science this year as well as psychology since I am interested in criminology. I don't think I've had a bad experience with O'Connor. I transferred from a different school where students were very limited on what to do since it was a smaller school. Attending O'Connor has made me experience new things and meet others who were both similar and dissimilar to me. I have learned about fields ranging from engineering to astronomy. I would like to see more female students in male dominated classes/clubs. It was difficult to recruit girls to my robotics team when there were mostly guys. I think women in stem can be encouraged more.

The administration staff are poorly mannered. I’m so glad I got my daughter withdrawn from this school. The staff act so rude and disrespectful as if they were the students. Please do better and at least say hello to. The parents no matter what’s going it’s unprofessional

The teachers don’t seem to care if the students learn or retain information. Everything is staar test centered (like most of Texas). Male students are often not spoken to if their behavior is poor whereas female students seem overly punished for the same behaviors. This also includes drug activity o...

Let me start off with I am a huge supporter of public education, our teachers and give a lot of second, third, fourth chances. Texas schools are a 3rd world country so if you're up north or east, stay.O'Connor administration is weak, biased, and it's not pro-student, at all. They are pro-funding and...
