Reading US school ratings: what scores can and cannot tell you

When you first meet grades, scores and colours while looking at US schools, it is hard to know how far to trust them. This guide is for parents and students looking at US public schools. After reading it, you will be able to tell what rating data shows and what it leaves out, and you will have questions ready for the school.

There is no single national grade in the US

If you are used to hearing about a school's 'grade level' at home, you might expect a national grade in the US too. Yet even the sources in this guide show that methods differ by state. A 'B' in one state or 'Green' in another cannot be lined up directly. So start by checking which state, which body and which year the data comes from.

Texas: an A-F grade combines three domains

According to the Texas Education Agency (TEA; as of 29 October 2026), Texas gives schools and districts A-F ratings. They rest on three domains: Student Achievement, School Progress and Closing the Gaps. The method is set out in the yearly accountability manual, and parents can look up ratings on TXschools.gov.

A single letter hides several domains. For example, two schools with the same grade may differ: one strong on achievement, the other on progress. The letter alone will not show that. TEA also advises noting the rating year, so do not mix last year's grade with this year's.

California: indicator colours instead of one overall grade

The California Department of Education (as of 29 October 2026) says the state uses the School Dashboard to show results by indicator rather than an overall grade. Graduation rate, academic performance, suspension rate, English learner progress, college/career readiness and chronic absenteeism each get a colour, from Blue (highest) through Green, Yellow and Orange to Red (lowest). Each colour combines current status with change from last year, and results are also shown by student group, including English learners.

The colour shows not only 'how high now' but 'which way it is moving'. Seeing a student group like your child's can reveal what an average hides. On the other hand, with several indicators it is hard to say simply 'good' or 'bad'. Deciding which indicators matter most to your family makes the Dashboard much easier to read.

What lies outside the score: a school's basic profile

Scores and grades show only part of a school. Though it is an Australian example, ACARA says on My School (as of 31 October 2026) that NAPLAN is only one part of school performance and does not measure overall school quality. It also states that there are no league tables and suggests visiting schools and talking with teachers and principals. The attitude is worth borrowing.

Basic statistics on US public schools are in the Common Core of Data (CCD) kept by the National Center for Education Statistics (NCES). NCES (as of 4 November 2026) says school-level data include address, operating status, school type, enrolment by grade, counts for racial and ethnic groups, students eligible for free or reduced-price lunch and classroom teachers in FTEs. These numbers are not ratings; they describe a school's background and size. The school count on the guide page is for 2015-16, so check NCES for the latest year.

Grade bands differ too

According to the US Department of State (as of 29 October 2026), US schooling runs 12 grades after kindergarten. But which grades make up elementary, middle and high school, and the age cut-off date, depend on state and district rules. So when comparing 'middle school' scores, first check that the two schools teach the same grades. The same name can cover different grades, and the numbers then mean different things.

Sam's one-line tip

Treat a grade or colour as the start of your questions, not the answer: check the year and the domain, then ask the school directly.

Checklist

• Do you know which state and which body the data comes from?
• Have you noted the year of the grade or colour?
• Did you look at domain-level results (achievement, progress and so on) behind an overall grade?
• Did you look for results for a student group like your child's?
• Did you check which grades the school covers?
• Did you look at basic statistics such as enrolment and free or reduced-price lunch counts?
• Are you avoiding a direct comparison of grades across states?

Ask the school

• Which year the published grade or colour is for, and whether anything has changed since
• How the school supports students similar to your child
• The grade range the school covers and its age cut-off date
• Whether visits or meetings are possible, and how to request one

Rating methods and how they are published differ by state and district and can change, so confirm the latest details with the state education agency and the school.

Your next step

Pick one school you are interested in, open its grade or indicators on the state education agency's site, and note the year and domains. Then send the school two questions based on your notes.
