When looking at properties in Hartsdale, you will often hear about the Edgemont school district. However, you may have noticed that scores can vary from site to site. To put it simply, even though it's the same school, one site might show a score of 10 while another shows 8.

Greenvale School, which is part of the Edgemont school district, received a perfect score of 10 according to GreatSchools. In contrast, Edgemont High School within the same district has been shown to have scores of either 8 or 10 depending on when the data was accessed. This is why it can be difficult to judge a school based on just one number.

The school scores displayed on real estate websites are mostly derived from ratings given by GreatSchools, a nonprofit organization. These scores are calculated by combining test scores, college readiness, and equity indicators. If these terms are unfamiliar, think of it this way: test scores are the students' scores compared to the state average, while college readiness looks at SAT/ACT scores, AP course completion rates, and graduation rates. Equity measures the extent of score disparities among different student groups.

This calculation method can vary slightly from state to state and also changes over time. Therefore, depending on when you check a site, the same school may show different scores. If you look at the Greenvale School page, there are other important factors to consider beyond just the score. The student-to-teacher ratio is lower than the New York state average, and the attendance rate is 93%, which is higher than the state average of 73%. These factors can provide a better sense of the actual atmosphere of the school than just one test score.

In fact, the composition of GreatSchools scores varies slightly by school level. Elementary and middle schools include an additional category called academic growth, which measures how much students have improved compared to the previous year. In contrast, high school ratings place more emphasis on college readiness instead of growth. This means that even if both Greenvale School and Edgemont High School have a score of 10, the components that make up that score are different.

The Scarsdale school district, located right next to Hartsdale, is also a popular area for Korean families to compare. Both districts receive high scores, but Scarsdale has a larger district size and generally higher property prices. With the same budget, Edgemont is often more accessible, and the differences in size and price can have a greater impact on actual living decisions than the score difference. Visiting schools in person to observe the classroom atmosphere can also fill in gaps that a score sheet cannot reveal.

When comparing two areas within Hartsdale with the same budget, it is common for assigned schools to be divided by just one road. If you find a house you like, it's best to input the address into the school assignment system to confirm. There have been cases where people relied solely on the school district name listed on real estate sites and ended up with a different assigned school.

In summary, here's the order of steps to check. First, look at the detailed components that go into the score rather than just the score itself. Next, observe whether the ratings have fluctuated over the past few years. Finally, directly check the assigned school address on the district's website. While there are clear reasons why Korean families prefer districts like Edgemont or Scarsdale, it's safer to verify that preference with multiple indicators rather than relying on just one score.

This information is not investment or legal advice, and school district boundaries and ratings change frequently, so please verify the assigned school for the specific address before making any contracts and consult with professionals if necessary.
