Good school! They take time with each student when they need it.

Just want to say that I am doing perfectly fine at this school, I've gotten great grades and have not had so called problems with this "horrible" school. Drugs are all a factor of the community the school is surrounded by, there is a risk that students have more exposure to drugs by being in this type of area but you must realize this is at the student's decision. It is in no way the school's fault for the community's faults or flaws. Thornton is a great school and can be represented with the students that have graduated from it. We've had a student go to Brown and another go to MIT. Please realize that just because the community has its flaws does not mean the school does. Their courses are great and our school is not represented by those who are not as polite or by drugs.

Where do I even begin, this school is so horrible. The students the go there are so rude and disrespectful, they have so many problems with drugs, attendance, fighting and much more. My son has been to 4 different high schools because we are constantly moving and when I told my co-workers that my son guys goes there they all tell me they have took there children out of that school, either because of drugs or the attendance. My son has been doing amazing his past three years of high school he is a junior now, he has never been suspended nor expelled but when he came to this school he started to smoke weed, I found out he was doing acid and cocaine, then he got suspended for missing class and I received a letter saying I would have to appear in court if his attendance continued. I immediately took him out and took him to drug classes and we moved out of Thornton and he no longer goes to Thornton High School and he has straight A's and B's and hasn't even 1 class. I just highly recommend if you want to keep your kid on the right path and out of trouble do not go to Thornton High.
