A family looking for a home in the Bronx was puzzled by the scores of nearby high schools. They saw that Bronx Science High School, just a ten-minute walk away, had a score of 10. However, the actual neighborhood high school assigned to that home had a much lower score. This was a case where the visible prestigious school and the actual assigned school were different.

This confusion often arises due to the unique structure of New York City. Recently, the market has seen a mix of specialized high schools, like Bronx Science, which require an entrance exam, and general high schools that are automatically assigned based on neighborhood addresses. It can be easy to get confused about which type of school the scores on real estate websites refer to.

New York City has a complex structure that includes specialized high schools that require entrance exams, schools assigned by lottery after application, and schools automatically assigned by address. If you don't first distinguish which type of school the scores on real estate websites refer to, you might end up looking at numbers that are completely different from the scores of the school your child will actually attend.

When looking at the score variations within the Bronx, the differences are clear. Bronx Science High School and Bronx Charter School for Excellence both have scores of 10. In contrast, Bronx Haven High School has a score of 2, and Bronx Aerospace High School has a score of 4. There are also schools like Bronx Collegiate Academy that fall into the average range with a score of around 5. The reason for these score differences within the same borough is due to variations in admission processes, student demographics, and curricula among schools.

To understand the three elements that make up these scores, consider the following: test scores reflect academic achievement compared to the New York state average, college readiness is calculated based on graduation rates and participation in advanced courses, and equity indicators assess whether various student groups achieve evenly. Specialized high schools tend to score high in all three categories because their admission processes are geared toward students with high test scores. The weight of equity indicators varies by school level, with middle and high schools generally placing more emphasis on this factor than elementary schools. Since specialized high schools are at the high school level, this aspect has a greater impact on their scores.

Therefore, do not make judgments based solely on one number; consider the following as well:

• Determine whether the score refers to a school that requires an entrance exam or one that is automatically assigned by address.
• Check whether the recent trend in scores is increasing or decreasing.
• Look at the student-to-teacher ratio compared to the New York state average.
• Verify the actual assigned school for the property address directly on the education department's website.

Also, take a look at the student-to-teacher ratio. A lower ratio than the New York state average indicates that there are fewer students per teacher, which can suggest differences in the learning environment that may not be apparent from the scores alone.

In one case I reviewed, a family signed a contract based solely on the specialized high school score, only to later find out that their child could not attend that school and would have to go to the neighborhood assigned school instead. It's important to remember that even within the Bronx, the actual assigned school can vary significantly depending on the block.

When reviewing scores, be sure to check the trends over the past three years. In areas like the Bronx, where new charter schools are continually being established, there may not be enough data in the early years to provide stable scores.

Sometimes, multiple school names appear on real estate websites. In such cases, it is safer to first identify which of those schools is the actual assigned school before checking the scores.

For families moving to New York from other states or countries like Korea, this dual structure can be unfamiliar. It is safer to use the scores as a reference and make verifying the assigned school a necessary step before signing a contract.

This article is not investment or legal advice, and it is recommended to confirm the assigned school again through the school district office and consult with professionals before finalizing any contracts.
