As you review the school rankings data, please be aware that some of the information from certain demographics is missing. The reason for this omission is that the data has been redacted from the source data itself due to low population samples in these specific demographic groups.

Redacting data from low population samples is a necessary step to ensure the reliability and accuracy of the results, as small sample sizes may not be representative of the broader population. Additionally, this measure helps protect the privacy of individuals belonging to these demographic groups.

Open Quote 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

Open 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.

Open Quote 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

Open 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

About Students eligible for discounted/free lunch:

The National School Lunch Program (NSLP) provides low-cost or free meals to students in U.S. public and nonprofit private schools based on household income. Those with incomes below 130% of the poverty line receive free lunch, while those between 130% and 185% qualify for reduced-price lunch. The percentage of students receiving free or reduced-price lunch serves as a marker for poverty, as it reflects the socioeconomic status of families in a given school or district. A higher FRPL rate typically indicates a higher concentration of low-income families, suggesting that the school or district may face additional challenges in providing adequate resources and support for student success.

About Student-Teacher Ratio

Student/teacher ratio is calculated by dividing the total number of students by the total number of full-time equivalent teachers. Please note that a smaller student/teacher ratio does not necessarily translate to smaller class size. In some instances, schools hire teachers part time, and some teachers are hired for specialized instruction with very small class sizes. These and other factors contribute to the student/teacher ratio. Note: For private schools, Student/teacher ratio may not include Pre-Kindergarten.
