Summary

R. Rex Parris High is a public high school serving 469 students in grades 9-12 within the Antelope Valley Union High district in Palmdale, CA, but it faces severe academic challenges, ranking in the bottom 10% of California high schools.

The school's performance metrics are critically low, with only 16% of students proficient in English, less than 2% proficient in math and science, and a graduation rate of 45% compared to a state average of 87.5%. Furthermore, chronic absenteeism affects 68% of students, and the dropout rate is 35%. These outcomes are significantly worse than at other local schools; for example, SOAR High (Students On Academic Rise) in the same district has a 100% graduation rate and test scores above state averages, while William J. (Pete) Knight High graduates over 90% of its students.

While the school serves a high-need population, the stark contrast with nearby schools suggests challenges are specific to the school environment. A recent positive step is a reduced student-teacher ratio. However, the school receives notably less funding per student than other district schools, and urgent, comprehensive intervention is needed to address the foundational issues in attendance and instruction to improve outcomes for all student groups.
