Many people start by checking real estate apps to look at school scores when searching for a home. They often look at the numbers next to the property photos first. However, many people surprisingly overlook what these numbers, specifically the GreatSchools score, actually mean. Simply put, it's a number that reflects how well students at that school performed on tests compared to the state average, rated on a scale from 1 to 10.

Within San Francisco, there is quite a range in these scores. The Chinese Immersion School At Deavila received a score of 10, while Garfield Elementary School scored 9. West Portal Elementary School and Jefferson Elementary School both received a score of 8. In contrast, Chavez Cesar Elementary School only scored 3. This variation in scores within the same city shows that it's difficult to judge school districts based solely on neighborhood names.

If the terminology is unfamiliar, think of it this way: Test Scores are the base score, and an Equity score is added to it. The Equity score looks at how evenly grades, attendance, and disciplinary records are distributed among different student groups. For elementary and middle schools, these two factors are combined to produce the final score. Therefore, having good test scores doesn't automatically mean a high overall score.

It's also good to be aware of College Readiness. In simple terms, this is a measure that combines SAT or ACT scores, graduation rates, and participation rates in advanced courses like AP. In high school scores, test scores and growth are roughly divided into thirds.

Here are some additional factors to consider alongside the scores:

• Whether the scores have been trending up or down in recent years
• How the student-to-teacher ratio compares to other schools
• Actual reviews left by parents
• Reconfirming with a district map that the property address is indeed assigned to that school

Looking at the student-to-teacher ratio can also be helpful. Simply put, this number shows how many students each teacher is responsible for. A lower ratio is often said to make individual instruction easier, but there can be significant differences based on school size, so it's better to view it as a comparative reference rather than an absolute standard. For families moving from out of state, it's also wise to consider property taxes and insurance conditions along with school scores. In California, property taxes are based on the purchase price and have limited increases thereafter, which differs from the methods used in other states. However, tax rates and specific regulations can vary by county, so it's important to check. Private schools often do not take state-administered tests, so they may not have a GreatSchools score. If considering private schools, it's necessary to verify through the school's own materials or visit for consultations instead of relying on scores. Insurance rates can also vary significantly within California based on local fire risk, so it's advisable to ask about this when checking property locations. Korean families often prioritize checking the actual curriculum structure, such as immersion programs or after-school academic support, over just the scores.

Don't judge solely based on scores; it's important to develop a habit of checking trends, ratios, reviews, and the actual assigned schools. Especially since school district boundaries can change over time, if you find a property you like, be sure to double-check the district map. By looking at trends, ratios, reviews, and actual assignments, you can gain a much more comprehensive understanding of the school.
