4/10GreatSchools RatingParent Rating AverageDonna High School is actually a great school. The work is incredibly rigorous and the teachers are amazing in every way. Everyone at DHS is committed to helping the student learn and ultimately graduate and attend a university or college. Donna High is a great school regardless of the bad media and reputation that people associate with it. The school is really disciplined and responsible and will ensure success. Also, the school has a great deal of spirit and traditions that just reinforce a great high school education and atmosphere. DHS is the place to be.Student Review13y ago - Capt D Salinas II Elementary School

7/10GreatSchools RatingParent Rating AverageI can't wait to get my child out of this school! They put her in another parents vehicle they keep changing her teacher. As for me and my child's first experience because my child is in pre-k , I think they have ruined it. They always ask for money. When we go to functions nothing is organized or they don't have a place for us to sit and my child has fallen due to the teacher walking so fast. The principal actually said to me that she wasn't going to baby anyone and if I didn't like it then to take my child out of school. Who would say that if they are the ones running the school.

8/10GreatSchools RatingParent Rating AverageThis school is great!! Teachers are very good they won't give up on your kid! Donna has a lot of gangs but with their disciplinary rules and strict dress codes their is no chance your kid will become a follower. The only down fall at Donna ISD is their district and school websites never get up to date!! Come on Donna this is 2014!!!Parent Review11y ago
