Summary

Aspen Elementary is a 332-student K–5 school in Thousand Oaks, part of Conejo Valley Unified. Its 2025–26 proficiency rates were above California’s in English language arts (ELA), math and science, but below district rates in all three. The biggest concern is the sharp decline from Aspen’s 2022–23 results: proficiency fell 11 points in ELA, 22 in math and 21 in science.

Compared with nearby schools, math is Aspen’s relative strength, while ELA and science are more middle of the pack. Its math proficiency was 48%—third among eight nearby schools and above their 45% median. ELA was 57%, fifth among the eight and above their 49% median; science was 46%, fourth and just below the 48% median. Aspen was also above state rates in each subject—by 8 points in ELA, 10 in math and 10 in science—but below district rates by 10, 8 and 8 points, respectively. Fifth-grade math stands out as a weakness: 30% were proficient, compared with 61% in third grade and 57% in fourth; Aspen ranked sixth of eight nearby schools in fifth-grade math. Chronic absenteeism is a clear positive: 2% at Aspen, compared with 11% districtwide and 18% statewide.

SchoolDigger gives Aspen four stars and places it at the 71st statewide percentile for 2025–26, down from the 88th percentile in 2022–23; among eight nearby schools, its current percentile is tied with one peer and below the two local leaders at the 88th and 92nd percentiles. SchoolDigger’s subgroup ranking also flags a sharp decline in how well the school serves Hispanic students: their ranking fell from the 72nd percentile in 2024–25 to the 28th in 2025–26, compared with Aspen’s overall 71st percentile. For context, the 2024–25 student–teacher ratio was 16.6, the second-lowest among nearby schools, and 20% of students were free/reduced lunch eligible that year, the lowest share among the seven nearby schools with the same measure.

Not pleased with front office staff. Do not care for the interpersonal skills of principal Mills. If you are not part of the PTA then you are not part of the crowd and dont have a fighting chance for your concerned voice to be heard. Not pleased with this school. Test scores show the declining rank of this school as it should rank higher in the area that this school is located. Funding raised through the PTA needs to be used towards schools technology.

I have been a part Of the Aspen Family for ten years now and I am constantly amazed at the consistency of excellence at this school. The teachers are positive forces in our children's learning and have been excellent role models also. Their dedication and positive attitude permeate throughout the classrooms and the overall learning climate is one of cooperation and compassion. The staff work together in a team teaching module to get the best of all ideas to each and every classroom. I have seen that the preparation for culmination to middle school has been well planned and that the transition for students was made much easier due to the high caliber and expectations set by the teachers and staff.

The students are consistently supervised by a caring and diligent group of yard supervisors who keep an everpresent and watchful eye on our children. The school has a zero tolerance policy of bullying and has an intact plan for the learning, education and response in these matters.

The Parent Faculty Association has had a long standing role in keeping Aspen as one of the premiere elementary schools in the district, raising over $50,000 a year to supplement the classrooms in computer technology, library services, (which are not supported by the state), music, dance and art education and family services. All of which is done through parent volunteerism and not through out of pocket sales of items such as magazines and such. They have a well organized group of parents that continue to grow and change with the times and the needs of the school. The communications with in the school are superior and parents are always in the loop of what is going on in the school and in their child's classroom.

The campus is a beautiful green grassy, well landscaped campus with newly planted trees, outside planters, three grade level learning gardens and an outdoor classroom. There is an ongoing and award winning green incentive within the school with recycling programs, waste reduction programs and projects, composting programs and education.

I have and will continue to reccomend Aspen to anyone who is looking to move to the area, change schools or whatever reason they may have in finding a new school. Close Quote
