How to Evaluate a School
What to look at, ask, and weigh when sizing up a school — from data and ratings to what you observe on a visit.
Evaluating a school means looking beyond a single rating to examine what drives it — staffing stability, growth data, culture, safety, and how the school serves students with specific needs. Visiting in person and asking direct questions of staff gives you information no website can.
A school's rating is a starting point, not an answer. This section helps you move past the number and understand what produces it — and what it leaves out. The pages here cover every layer of evidence that bears on whether a school is likely to work well for your family: published data, in-person observation, conversations with staff, and the signals that are easy to miss.
The pages are grouped around three questions: What does the data actually say? What do you see when you show up? And how do you put it all together? You do not need to work through every page — use the checklist and the red-flags guide to orient yourself, then go deeper on the dimensions that matter most for your child's situation.
If you have not yet narrowed down which type of school you are considering, start with the Types of Schools section first. If you already have a school in mind and need to understand the enrollment process, Enrollment and Zoning is the right place. This section sits between those two: it assumes you have some options in front of you and want to judge them carefully.
This section does not cover what types of schools exist or how zoning and enrollment deadlines work — those are handled in Types of Schools and Enrollment and Zoning respectively. If you are evaluating a school because you are considering leaving one, see Changing Schools.
What you need to understand first
Data vs. what you observe
Published ratings, test scores, and report cards describe a school in aggregate and on a delay. What you see during a visit — how adults speak to students, how hallways feel, how staff answer hard questions — reflects current conditions that data cannot capture. A sound evaluation uses both and notes when they conflict.
Growth measures vs. proficiency
Proficiency rates show how many students meet a benchmark at one point in time. Growth measures show how much students learned over a period, regardless of where they started. A school with modest proficiency scores but strong growth may be serving students more effectively than its rating suggests — and the reverse is also true.
Staffing stability as a quality signal
High teacher turnover disrupts instruction, strains culture, and is often a sign of broader problems in leadership or working conditions. Schools with stable, experienced staffs tend to have more consistent instruction. Asking directly about turnover rates and how long the principal has been in the role gives you information ratings rarely surface.
School culture and discipline
Culture shapes daily life for students more than any single metric. It includes how conflict is handled, whether students feel safe enough to take academic risks, and whether adults model the norms they enforce. Discipline records, suspension rates, and how staff describe their approach during a tour are all evidence worth weighing.
Fit, not just quality
A school that performs well on average may not serve every student equally well. How a school supports students with disabilities, English learners, or advanced learners is a separate question from its overall rating. Evaluating fit means asking specifically about the programs and supports relevant to your child's situation.
Weighing parent reviews
Parent reviews reflect real experience but carry selection bias — families who felt strongly enough to write a review are not a representative sample. A pattern of similar comments across many reviews is more meaningful than any single account. Reviews are most useful for surfacing questions to ask in person, not for reaching a verdict on their own.

Mistakes to avoid with How to Evaluate a School
Treating a school's overall rating as the whole answer
Why it happens: Ratings compress many signals into a single number, which makes them easy to compare but easy to misread — a school rated highly overall may have significant gaps in specific programs or grade levels.
What to do instead: Use the rating to identify which schools are worth a closer look, then go one level deeper into the data — growth scores, subgroup performance, and staffing figures — before drawing a conclusion.
Visiting a school without a list of questions prepared
Why it happens: Tours move quickly and feel social, so it is easy to leave having learned nothing beyond what the school chose to show you.
What to do instead: Prepare specific questions before you arrive — about teacher turnover, discipline approach, and how the school handles students who need extra support — and ask them directly of staff, not just the tour guide.
Skipping the special education question when it seems irrelevant
Why it happens: Families whose children do not currently have identified needs often assume special education support does not apply to them, but how a school resources and staffs its support services reflects its overall approach to students who need more.
What to do instead: Ask how the school identifies and supports students who are struggling, even if you do not anticipate needing those services — the answer tells you something about the school's capacity and culture broadly.
How to Evaluate a School: common questions
What should I look at first when evaluating a school?
Start with the state report card for the school, which is publicly available and covers test performance, chronic absenteeism, and sometimes staffing data. Then identify the one or two dimensions that matter most for your family — special education support, discipline approach, class size — and look specifically at those before visiting in person.
How do I know if a school's test scores are actually good?
Compare scores to the district average and to schools serving similar student populations, not just to a statewide benchmark. Also look at whether scores reflect proficiency at one point in time or growth over time — a school where students consistently make more than expected progress is doing something worth understanding, even if raw scores look average.
What are red flags during a school visit?
Staff who deflect or become defensive when asked direct questions about discipline or turnover. Hallways or classrooms that feel chaotic or where adults seem disengaged. Vague answers about how the school supports students who struggle. None of these is automatically disqualifying, but any of them is worth following up on before making a decision.
Can I trust parent reviews of schools?
Treat them as a source of questions rather than conclusions. Families who post reviews skew toward strong reactions — positive or negative — so any single review is limited evidence. A consistent pattern across many reviews on multiple platforms is more meaningful. Use what you read to generate specific things to ask or observe when you visit.
How much does class size actually matter?
Class size is one factor among several. Smaller classes can allow more individual attention, but the effect depends heavily on how teachers use that opportunity. A school with slightly larger classes and strong, stable teaching staff may serve students better than one with small classes and high turnover. Look at staffing ratios and teacher retention alongside class size figures.
What questions should I ask the principal?
Ask how long they have been at the school and how teacher turnover has changed during that time. Ask how the school identifies students who are falling behind and what happens next. Ask what the school is actively working to improve. The content of the answers matters, but so does whether the principal engages the questions directly or retreats to talking points.
