Public vs Private School in the Conejo Valley: What Parents Should Know

The public vs private schools Thousand Oaks question usually starts with one number: 13 years of tuition. At today's local rates that is $14,419 a year at the town average and $33,280 a year at the top priced school, before any future tuition increases. Nearly half of local private families offset part of that with aid, and the public district those families would otherwise use tests well above the state average. Here is what the data shows.

How strong is Conejo Valley Unified academically?

Conejo Valley Unified School District (CVUSD) is a K through 12 district headquartered at 1400 East Janss Road in Thousand Oaks and governed by a five member board elected by trustee area. It enrolled 15,442 students in the 2025/26 school year, according to Ed Data, compared with 15,999 students across 27 schools in 2023/24, when enrollment was already 2.2% lower year over year.

Performance has held up. The 2025 CAASPP results presented to the board on March 18 showed CVUSD students roughly 50 points above the state average in both English language arts and mathematics, as reported by the Thousand Oaks Acorn. Five schools, Colina Middle, Ladera STARS Academy, Lang Ranch, Maple, and Sycamore Canyon, earned 2026 Honor Roll School distinction from Educational Results Partnership, and Thousand Oaks High and Westlake High students claimed 14 of the top 35 scores at a regional science fair, per the district. Regular attendance was 88% in 2025, up about one point from 2024, according to GreatSchools.

Two public features have no private equivalent. First, voter approved Measure I bond funds have delivered new facilities at Newbury Park High, Thousand Oaks High, and Westlake High. Second, every CVUSD school is scored on the California School Dashboard, which rates ELA, math, chronic absenteeism, suspension, graduation rate, college and career readiness, and English learner progress on five color levels from red to blue. Private schools publish what they choose. Our ranking of Conejo Valley high schools puts the three CVUSD campuses in context.

How do CVUSD and Conejo Valley private schools compare side by side?

The CVUSD vs private school comparison is less about one system beating the other and more about what each one guarantees.

One nuance on the public side: CVUSD serves Thousand Oaks, Newbury Park, and only parts of Westlake Village, so "Conejo Valley" and "CVUSD boundaries" are not the same thing. Choice exists within the system too; Acacia Magnet School for Enriched Learning enrolled 369 students in 2023/24, and EARThS Magnet and the Conejo Academy of Leadership and Language Immersion are other specialized campuses.

Is private school worth it in Thousand Oaks?

Is private school worth it in Thousand Oaks? Only if you are buying something the district cannot supply. The academic premium is hard to prove here: CVUSD already tests roughly 50 points above the state average, and its schools are scored on a public dashboard that private schools are not. What private tuition reliably buys is smaller rooms (17 to 18 students on average locally), a specific philosophy, faith based instruction, or a model like Fusion Academy's one to one classes.

Run the math honestly. Thirteen years of tuition at the $14,419 average, or at Oaks Christian's $33,280, adds up fast, and neither rate includes future increases. With 45% of local private students on aid, the net can be lower, but the application cycle matters too; Oaks Christian admits 59% of applicants with a February 1 deadline, so a "we will just go private" fallback is not guaranteed. Families whose child has an IEP or 504 plan should also compare the services each option provides, which we cover in our guide to special education resources in the Conejo Valley.
