This is the story of a family preparing to move to Phoenix from another state. While looking for a home, they started paying close attention to the school scores listed on real estate websites. They found a neighborhood they liked, but the assigned elementary school had a score of 4. Although the neighborhood appeared quiet and tidy, they couldn't understand why the score was so low.

In fact, within the Phoenix Elementary School District, there are schools like Capitol Elementary School and Lakeview Elementary School that have a GreatSchools score of 4 out of 10. In contrast, Sequoya Elementary School and Sonoran Sky Elementary School, just a few miles away, received a score of 10. This data is based on GreatSchools as of August 2026. There is a significant variance even within the same school district.

What needs to be clarified here is what this score actually measures. The GreatSchools score is primarily a combination of four factors: test scores, student growth, college readiness, and equity. According to GreatSchools' official methodology page, a weight of 0.45 is given to the higher of the test scores and student growth, while the other categories receive a weight of 0.27.

Thus, a score of 4 does not necessarily mean that the students at that school are generally falling behind. It is more indicative of a relatively lower achievement level compared to other schools in the state. Growth or equity indicators may be strong, and this information can be checked separately on the school's profile page.

If you are a Korean family, it is important to dig a little deeper here. Don't dismiss a neighborhood based solely on the score; you need to see whether that score reflects just test scores or also includes growth. Areas with a high percentage of low-income households tend to have lower test scores, but this does not necessarily correlate with the quality of education.

There are other factors to consider alongside the scores. Look at the student-to-teacher ratio, whether the school has been trending upward or downward in grades over the past 3 to 4 years, and the reviews left by parents who have actually sent their children there. Reviews often contain insights about the atmosphere and teachers' attitudes that are not captured in numbers.

Most importantly, it is crucial to verify the actual assigned school based on your home address. School district boundaries can often change with just a road in between, and the school you like on the website may not be the one your child is actually assigned to. Before making an offer, please check directly on the school district's website or the education department's boundary map.

• Have you verified the assigned school name on the school district boundary map?
• Have you looked at growth and equity factors in addition to test scores?
• Have you checked the trend of grade changes over the past 3 to 4 years?
• Have you considered parent reviews and the student-to-teacher ratio together?

In rapidly developing areas like Phoenix, school district boundaries can be redrawn within a few years. There is no guarantee that the score you see today will remain the same when your child enrolls. Therefore, it seems wise to use the score as a starting point but to make decisions after reviewing multiple sources of information.

If you are a family moving from another state, there is one more thing to check. Those coming from states like California or New York, where property tax rates are high, often feel relieved by Arizona's relatively low property taxes. However, in areas with a good reputation for school districts, there may be additional local bonds or school-related taxes, so be sure to check the actual monthly payment amounts by county.

Instead of rushing to sign a contract, it might be a good idea to rent for a semester to experience the commute and community atmosphere firsthand. While scores provide data, it can be difficult to know if the environment is one where your child can truly adapt without living there.
