My son came home one day, and said that he hated centennial. It was the first day so I let it slide. At the end of the year he said again he hated centennial, and I asked why? He said the teachers were terrible, and the students were all snobby. He mentioned the only reason centennials a good school is because everyone that goes there can afford tutors. Close Quote

My daughter could have easily gotten into the humanities program but we chose to not enroll. I think the program is way oversold. I don't know how you can teach a "Humanities" program and omit European history (students have to take that as an elective!) She is in GT and AP courses and I do not feel she has been shortchanged at all. My only issue with Centennial are the parents who demand their children be put into classes they are not prepared for (AP >, probably Humanities as well) so the teachers have to teach down to them, until they finally drop out or are asked to leave.

Regarding the Humanities program.... My kids were part of this program and all of them felt they had an advantage in college over other students. They did not panic when assigned long or last-minute papers freshman year. They were used to it. I have no idea how placement is handled there now. I only know it was a fantastic program, and I commend the teachers who were a part of it. Close Quote

Centennial High School is a truly renowned school and is very much soutght after by many parents. I have one child who is currently in school, and another entering next fall. There is one very bad thing about Centennial though.

Centennial High school has a program called the Humanities program. As with other schools, students were recommended, and those who were not were allowed to waiver with the approval of the teachers. Somehow, too many people were entered into the Humanities program, so many had to be taken out. Instead of trying to get everyone in, the school randomly picked stuydents. Is this fair? Some students are going to experience a richer educational experience, and have a better college resume because of sheer luck. This is the reason i have left out two stars.......... :( Close Quote
