When looking for a home in Los Angeles, you might find a house you like on Zillow, but the nearby elementary school has a score of 8.

However, when you check another site, the same school has a B grade.

"Which one is correct?"

At first glance, it can be confusing. But most of the time, it's not an error. Different companies have different methods for evaluating schools.

What you often see on Zillow or Redfin is the GreatSchools score. It usually ranges from 1 to 10, but it's not determined solely by test scores.

They also consider students' academic growth and performance by student groups, and for high schools, they include data related to college readiness.

On the other hand, Niche presents ratings like A+, A, B+.

They use various data, including not just test scores but also school life, teachers, facilities, and reviews written directly by students and parents.

So, you shouldn't simply compare a GreatSchools score of 8 with a Niche grade of B and think, "8 is higher than B."

It's easier to understand if you think of it as results from different tests.

Especially in LA, you need to be more cautious when looking at school scores.

Just because they share the same Los Angeles address doesn't mean all students attend the same school, and the entire LA County is not a single school district.

While LAUSD is a very large district, there are many separate districts in surrounding cities.

Ultimately, the important thing is the exact address of the home.

And just because a school received a score of 9 or 10 on GreatSchools doesn't automatically mean it's the best school for our child.

Overall test scores may be high, but there could be significant achievement gaps among student groups, or conversely, there may be schools with average current test scores but good student growth.

The same goes for parent reviews.

Reading reviews can provide valuable insights into the school environment and communication with teachers, which are hard to quantify with numbers.

However, if a school has only a few reviews, one or two good or bad experiences can significantly sway the rating.

The student-to-teacher ratio is also something people pay attention to, but this doesn't always accurately reflect the actual number of students in a classroom.

If a school has many specialized subject teachers or additional support staff, the ratio can appear lower.

So, I think it's best to use school scores as a sort of first filter when looking for a home.

Check GreatSchools, read Niche ratings and actual parent reviews, and if possible, verify the performance data provided by the school district for each school.

Finally, before signing a contract on a home, make sure to enter the address directly to confirm the assigned school. It's best to avoid relying solely on the schools listed on real estate sites.

In LA, the distance to school is also important. Even if it looks close on a map, morning traffic can change the situation. Whether there's a school bus or if parents need to drop off their kids every day is just as important as school scores in real life.

Ultimately, the school score of 8 is just a starting point for understanding schools.

You can repaint and renovate the kitchen later, but you can't change the school assigned based on your home address.
