One elementary school in the Anaheim Hills area is rated 10 on Zillow and has a high rating on Niche. However, just a few blocks away, Anaheim High School has a score of 4 according to GreatSchools. It can be confusing to know which number to trust when scores vary so widely between different sites and schools within the same city.

To summarize the actual figures: Anaheim Hills Elementary School has a score of 10, Peter Marshall Elementary School has a score of 7, and Canyon High School has a score of 10. In contrast, Anaheim High School has a score of 4, and Magnolia High School has a score of 5. These figures are based on GreatSchools data as of August 2026. Even though they are under the same city name, it means that there are actually multiple school districts and schools mixed together.

Let's first address why these numbers appear differently across sites. The school scores on Zillow and Redfin mostly use data directly from GreatSchools. On the other hand, Niche incorporates additional metrics such as surveys from students and parents, as well as facilities, to create its own ratings. It's natural for the same school to have different scores due to differing criteria.

When looking solely at GreatSchools scores, they are calculated by taking a weighted average of four categories: test scores, student growth, college readiness, and equity. According to GreatSchools methodology, a weight of 0.45 is given to the higher of the test scores and growth, while the remaining categories receive a weight of 0.27 each. This means that behind a single score, there are multiple layers of data.

Therefore, it seems unnecessary to worry about which number is correct when looking at different sites. Instead, it is more useful to check what basis the numbers are built upon. Depending on whether the score is test score-based or includes parent reviews, the same score of 10 can have different implications.

In areas like Anaheim, where high school districts and elementary school districts are separate, extra caution is needed. The boundaries between the Anaheim Union High School District and the Anaheim Elementary School District do not align perfectly, so if you choose a home based solely on elementary school scores, the assigned middle or high school may not meet your expectations.

For Korean families choosing a home in this area, it is advisable to check all three levels of schools: elementary, middle, and high school. By looking at the student-to-teacher ratio, recent trends in ratings, and actual reviews from current students' parents, you can make a judgment without being swayed by score differences across sites.

• Have you compared the same school across multiple sites (Zillow, Redfin, Niche, GreatSchools)?
• Have you checked the assignments for elementary, middle, and high schools separately?
• Have you verified the basis of the scores (whether they are test score-focused or include reviews)?
• Have you rechecked the actual assigned schools using district boundary maps?

Ultimately, it's not about picking a single number, but rather about looking at multiple numbers to read the common picture that emerges.

If you are moving from another state to California, it's also important to note that the property tax calculation method is different. In California, property taxes are based on the purchase price and have a cap on annual increases. In areas with good school districts, the purchase price tends to be higher, which also raises property taxes, so this should be factored into your calculations.

In summary, rather than focusing on a single number displayed on a site, it is more helpful to check the various layers that make up that number and to calculate the tax burden as well when planning your actual budget.
