Summary

Sierra High is a small public high school serving 119 students in grades 9-12 within the Azusa Unified School District, consistently ranking in the lowest tier of California schools.

The school presents a complex picture, with an exceptionally high graduation rate of 94.4% that exceeds both district and state averages, yet it faces severe academic challenges, including a 0% proficiency rate in mathematics and a chronic absenteeism rate of 61%. It operates with a very low student-teacher ratio of 7.7 to 1 and has a per-student spending of over $40,000, which is dramatically higher than nearby comprehensive high schools like Azusa High and Glendora High. In many ways—its small size, low ratio, and high absenteeism—it more closely resembles continuation schools such as Whitcomb Continuation High than a traditional comprehensive high school.

This creates a notable paradox where significant resources are allocated and students are graduating at a high rate, but standardized test scores remain critically low. The school's performance is volatile year-to-year, likely due to its small size, and it serves a student population with high economic need. For parents, it is important to look beyond the graduation rate and consider the full range of metrics, including the stark contrast in academic proficiency and attendance when compared to other schools in the area.

My name is Suzuki Farmer and I was a student at Sierra High school for 2 years in the year of 2010 and 2011.Wooohoo class of 2011! I went their both junior and senior year. I have to say if it was not for me having the opportunity to attend Sierra High, I would have not graduated. The staff is so friendly and so helpful. I have to give special thanks to Mrs.Kardashian of course , she is the absolute best! She is always smiling you will never see her mad well, unless you are doing something bad but either way she smiles almost all the time and the best part I have to say was being office aid ! the staff in the office is so fun and talkative! but we never got off task that forsure we had our moments of fun "chismes" but then when it came to office work, attendance or etc we did it right. I recommend this school to every kid out there . the teachers DO care , one of the realist teachers is Mr. Lowery he is so cool and also Mrs.Oldaker she was my fav. teacher anyhow know their are many rumors out their about the school but it's not how you think it is they have an officer on duty and they are always watching you , man I miss Officer Greg he retired the yr. I graduated he was funny and strict. for any of you who think you cannot do it and Graduate You can , and especially if you go to sierra high school they help so much it is so easy to learn. you will learn stuff you though was hard you will do things you never thought you could do because they break things down for you and don't rush into it or judge you when you get the answer wrong .well my work here is done! if anyone from sierra high reads this tell all the teachers and staff that i Say hello ! i miss them thanks alot Close Quote
