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.

Black families beware! This school is extremely racist and promotes a bullying culture. When it comes to protecting your child, they will not do it. The higher up admin sweeps incidents under the rug and do not address properly parents concerns! I do not recommend this school. The catch 22 is, out here in San Tan Valley, it is the better of the horrible schools out here. Some of the teachers are great. This is not a premier high school. Please believe all of the bad reviews you have read!!! Close Quote

I attend here, and have been to quite a few schools. This one (and the FUSD's for that matter) has a unique laptop program, and the staff care more about their students then most teachers. The students are also very supportive, I am a new freshmen and have not gotten one comment yet. 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.
