A family preparing to move to Omaha checked school scores first whenever they searched for properties. They said they developed a habit of looking at that number before the price. Recently, more people seem to be choosing homes this way.

The school scores displayed on Zillow or Redfin are ratings from a nonprofit organization called GreatSchools. They are represented by numbers from 1 to 10, with higher numbers giving a better impression. However, to read these numbers correctly, one must first understand what they are composed of. A school's overall rating does not automatically increase just because its test scores are good.

According to GreatSchools' official explanation, the ratings combine four elements: test scores, academic growth, college readiness, and equity. For high schools that have data for all four categories, achievement, growth, and college readiness each account for 33%. College readiness includes SAT or ACT scores, graduation rates, and participation rates in advanced courses like AP and IB. Equity examines whether performance is evenly distributed among various student groups, such as low-income or disabled students.

If you search for a school name on the GreatSchools website, the four detailed scores are displayed separately below the overall score. By clicking on the changes in ratings over the years, you can see whether the trend is upward or downward. If you only look at the overall score, you might miss these important details.

The growth metric is particularly significant. Schools with many high-achieving students can easily receive high ratings based solely on test scores. In contrast, growth measures how much students have improved compared to the previous year, so schools that started with lower scores can still receive good evaluations if they show consistent upward trends. Even if two schools have the same overall score, their actual situations can be very different.

In the Omaha area, there are indeed variations between schools. Wheeler Elementary School, part of the Millard Public Schools district, received a GreatSchools score of 9, and Millard West High School, also in the same district, has a score of 9. The Millard district consists of 37 schools with over 23,000 students. According to GreatSchools.org, this means that even within one district, scores can vary by school.

However, there are aspects that scores alone can overlook. Ratings are just a snapshot of results at a specific time. It's essential to look at whether ratings have been increasing or decreasing over the past few years. The student-to-teacher ratio is also worth examining. The fewer students assigned to each teacher, the more individualized attention students can receive. Reading parent reviews can provide insights into the school environment that numbers alone may not reveal.

The most important factor is confirming the actual assigned school. School boundaries can often split neighborhoods with just a road in between. The school listed on real estate websites may differ from the actual assigned school.

For families moving to Omaha from out of state, it's advisable to check property taxes and insurance conditions in addition to school scores. Tax and insurance systems vary by state, so judging based on the area you previously lived in could lead to missing important details.

When comparing multiple properties, it's a good idea to check the assigned school for each address separately. Even within the same Millard district, assignments can vary at the elementary school level, so it's efficient to narrow down a few homes you like and then cross-reference them with the district map.

To summarize the items to check:

• Recent trends and components of GreatSchools ratings, including test scores, growth, and college readiness
• Student-to-teacher ratio, parent reviews
• Actual assigned school and boundaries based on property address

School scores are just a starting point for judgment, not the whole picture. School boundaries change frequently, so be sure to verify the assigned school for the specific address before signing a contract.
