Summary

Sierra Elementary School is a PK–5 elementary school in Arvada, Colorado, serving 493 students as part of Jefferson County School District No. R-1. The school has earned a 5-star rating and ranked 75th out of 943 Colorado elementary schools in 2025–2026 (92nd percentile), with a decade-long track record of ranking in roughly the top 10–15% of the state. About 12.6% of students qualify for free or reduced lunch, and the student-teacher ratio is 17.6:1.

Academically, Sierra performs far above district and state averages. In 2025–2026, 70.5% of students scored proficient in English Language Arts, compared with 53.7% for the district and 44.7% statewide. Math proficiency hit 69.4%, versus 44.6% for the district and 37.3% statewide, and 5th grade science proficiency was 57.6% compared with 46.2% and 36.1% respectively. Math is a standout subject, with every grade level above 66% proficiency. Sierra outpaces the ten schools closest to it by roughly 12 points in ELA and 16 points in math, and it also outperforms nearby charter schools like Lincoln Charter Academy and Excel Academy Charter School. The contrast with Weber Elementary School, just 1.51 miles away, is especially striking: Weber's ELA proficiency (35.0%) and math proficiency (35.8%) are only about half of Sierra's.

Sierra also stands out for attendance: only 7.3% of students were chronically absent in 2024–2025, far below district (26.6%) and state (28.4%) averages. Its closest academic rival is Meiklejohn Elementary, another 5-star school about 1.75 miles away. Meiklejohn has a slight edge in ELA proficiency (75.9% vs. 70.5%), but Sierra is stronger in math (69.4% vs. 66.5%) and science (57.6% vs. 54.7%). One area to watch is 5th grade science, which has dipped from 66.7% in 2024–2025, and historical data shows the gifted and talented subgroup has had weaker results than other groups, though those figures are several years old.

What people are saying

by a parent
Sunday, September 21, 2025

While Sierra Elementary has some dedicated staff and offers a variety of activities for kids, my experience with the administration has been deeply troubling. Last school year, my child received a death threat, and I was disappointed by how the administration handled the situation. The school didn't seem to take the threat seriously, which left me feeling that my child's safety wasn’t a top priority.

This year, things took another troubling turn. Without any prior discussion or context, I was shocked to find out that CPS had been contacted due to a video that popped up on my 4-year-old’s YouTube. It was an upsetting and unnecessary escalation, especially considering the lack of communication beforehand.

To top it off, my interaction with the principal during this time was incredibly frustrating. The principal repeatedly talked over me and seemed uninterested in listening to my concerns. It felt as though they weren’t concerned with addressing the issues I was trying to raise, which made an already difficult situation worse.

As a parent, it’s incredibly important to feel that your concerns are taken seriously, and that your child's safety and well-being are a priority. Sadly, my experiences at Sierra Elementary have left me questioning whether this is truly the case. Close Quote
