Compare Schools: 12 Things to Look at Beyond Ratings and Test Scores

Comparing two schools should be easy.

It rarely is.

One school has a 9/10 rating. Another has a B+. One has higher state test scores. The other has smaller classes. Parents in one neighborhood rave about the principal. Families in the other talk about strong special education. One school has a better-looking number, but the other may actually fit your child better.

That is why a good school comparison should not begin with:

“Which school has the higher rating?”

It should begin with:

“What are the important differences between these two schools, and which ones matter for my child?”

That distinction is also becoming more important in search. In the Google Keyword Planner data used for SchoolReality, “compare schools” averages about 500 monthly searches and rose 900% over both the previous three months and the previous year.

This article gives you a practical way to compare schools without turning the decision into a spreadsheet contest.

First: make sure you are comparing the right schools

Before comparing quality, check eligibility.

A nearby public school is not necessarily:

• assigned to your address;
• in your district;
• open to transfers;
• open to your child’s grade;
• open to students outside a magnet or lottery process.

The National Center for Education Statistics maintains a public school search built from the Common Core of Data. NCES released preliminary 2025–26 directory files in July 2026, while enrollment and staffing details in its locator currently rely on the latest official files available for those measures.

Use NCES to confirm:

• school name;
• district;
• grade span;
• charter status;
• address;
• operational status.

Then use the district or local enrollment office to confirm actual assignment.

If you are comparing schools because you are moving, read Schools by Address: How to Find Your School District and Assigned Schools.

Now compare quality.

1. Current academic level

State test scores are useful.

They answer a real question:

How are students at this school performing on the state assessment?

Do not throw that information away because it is imperfect.

But do not treat it as a pure measure of teaching quality.

Current test scores can reflect:

• previous schools;
• family income;
• English proficiency;
• disability;
• tutoring;
• selective programs;
• neighborhood demographics.

Write down reading and math proficiency for each school if the state publishes them.

Then move immediately to the next measure.

2. Academic growth

If current scores tell you where students are, growth tries to tell you how much students are moving.

That is often closer to what parents mean when they ask:

“Is this school helping students learn?”

Growth measures vary by state, and not every school has an easy-to-compare growth score.

For district context, SchoolReality’s academic progress explorer shows comparable multi-year district trends using its separately labeled Stanford research layer.

When comparing two schools, ask:

• Does the state publish school growth?
• Is growth improving?
• Does high proficiency come with weak growth?
• Does lower proficiency come with strong growth?

A school can be high-performing and flat.

Another can be lower-performing and helping students gain ground quickly.

Those are different stories.

3. Attendance

This metric gets far less attention than it deserves.

If many students are missing large amounts of school, that affects:

• classroom continuity;
• group projects;
• teacher pacing;
• peer relationships;
• intervention;
• school climate.

Check:

• average attendance;
• chronic absenteeism;
• change over time;
• subgroup differences.

For district context, use SchoolReality’s attendance explorer.

A school with 18% chronic absenteeism that fell from 30% may be on a better path than a school at 18% that rose from 10%.

Do not compare only the current number.

4. Class size

Parents often confuse class size with student-teacher ratio.

They are not the same thing.

A school can have a 14:1 student-teacher ratio and still have homerooms with 22 or 25 students because teachers work in different roles.

Ask the school for:

• actual class sizes in your child’s grade;
• class-size targets;
• the largest section;
• how many sections are over target;
• what happens when enrollment rises after summer.

For middle and high school, ask about core subjects.

Read Student-Teacher Ratio vs. Class Size.

If two schools look similar on everything else, actual class size can be one of the easiest practical differences to understand.

5. Teacher stability

A school that replaces a large share of teachers every year can feel different from one with a stable staff.

Look for:

• teacher turnover;
• years of experience;
• current vacancies;
• long-term substitutes;
• principal turnover.

NCES’s national Teacher Follow-up Survey found that among public school teachers working in 2020–21, 84% stayed at the same school the next year, 8% moved to another school, and 8% left teaching.

Those national figures are context—not a school target.

Ask the school:

“How many teachers are new to this building this year?”

Then:

“How many are new to teaching?”

Those are not the same thing.

6. Student support

Counselors, psychologists, nurses and social workers may matter more to your child than a few points on a standardized test.

SchoolReality’s student-support explorer lets you compare district-level staffing.

At the school level, ask:

• Is there a full-time counselor?
• Is the psychologist based at the school or shared?
• Is a nurse present every day?
• How many schools does the social worker cover?
• Are any positions vacant?

For younger children, this can affect behavior support and family coordination.

For high school, counselor caseloads can affect:

• schedules;
• graduation planning;
• college applications;
• crisis response.

7. Special education

Do not compare schools by asking whether they “have special education.”

Every public school system has responsibilities under IDEA.

Instead ask:

• What service model exists at this school?
• Which special education teachers are assigned here?
• Are any positions vacant?
• Are speech, OT or psychology services on site?
• How are students included in general education?
• What happens when a required provider is absent?
• Does the school house specialized programs that affect staffing?

For a child with an IEP, this category may outweigh every school rating.

8. Discipline and school climate

A low suspension rate is not automatically good.

A high suspension rate is not automatically proof of an unsafe school.

Use discipline as evidence about how the school responds to behavior.

The U.S. Department of Education’s Civil Rights Data Collection includes suspensions, expulsions, law-enforcement referrals, school-related arrests and other climate information.

Ask:

• How often are students suspended?
• For what?
• Are a small number of students repeatedly suspended?
• Are there large subgroup differences?
• What behavior support exists before removal?
• What do current parent/student climate surveys say?

9. Advanced opportunities

A school can look strong academically but offer limited depth for students who need more challenge.

Depending on grade level, compare:

• gifted services;
• advanced math;
• Algebra I before high school;
• honors;
• AP;
• IB;
• dual enrollment;
• career and technical education.

Do not ask only whether a course exists.

Ask:

“How many students actually take it?”

Then:

“Has participation grown?”

The federal CRDC collects school-level information on AP course offerings and student enrollment in AP, which makes this an excellent future SchoolReality comparison layer.

10. Student demographics

Demographics do not tell you whether a school is good.

They do tell you important things about the community.

Check:

• enrollment;
• racial/ethnic composition;
• economic disadvantage;
• English learners;
• students with disabilities.

Then look at change.

A school whose enrollment grew 25% may be under capacity pressure.

A school losing students may face staffing or program changes.

A rapidly changing student body can also reshape language services, special education demand and school culture.

11. Program fit

This is the category ranking systems handle poorly because it is personal.

Your child may need:

• language immersion;
• autism support;
• dyslexia intervention;
• gifted math;
• a strong arts program;
• athletics;
• dual enrollment;
• small classes;
• a particular special education model.

A school with a lower rating can be the much better school if it provides the thing your child actually needs.

Write your top three must-haves before you compare.

That prevents the rating from defining your priorities for you.

12. Direction

This is the final question, and one of the most important.

Is the school getting better, worse or staying roughly the same?

Look for trends in:

• academics;
• attendance;
• enrollment;
• teacher turnover;
• class size;
• course access;
• discipline.

SchoolReality’s district data are especially useful here because many school comparison sites emphasize current status.

A school is part of a district system.

If the district is improving attendance, adding counselors and gaining academically, that context matters.

If it is cutting staff, losing enrollment and closing programs, that matters too.

A school comparison worksheet

Use this instead of adding everything into one score.

Then circle only three rows.

Those are your real decision criteria.

How to compare schools when one has much higher test scores

Do not pretend the difference does not matter.

Ask why.

Check:

• demographics;
• growth;
• course access;
• attendance;
• student-group outcomes.

A 20-point proficiency difference may partly reflect different student populations.

It may also reflect instruction.

The data usually cannot tell you exactly how much comes from each factor.

That uncertainty is a reason to use more evidence, not less.

How to compare schools in different districts

Now district context becomes even more important.

Compare:

• spending;
• academic trend;
• chronic absence;
• support staffing;
• teacher retention;
• graduation;
• student-group gaps.

Use How to Compare School Districts.

Two schools can look similar while the systems around them are moving in very different directions.

Visit after you have looked at the data

Data should improve your school visit.

It should not replace one.

Instead of asking:

“What makes your school special?”

Ask:

“I noticed chronic absenteeism fell last year. What changed?”

Or:

“How many fourth-grade classes are above the district class-size target?”

Or:

“The district has a high counselor ratio. How is counseling staffed at this school?”

Those questions get better answers.

Do not make reviews your tiebreaker until you read them carefully

Reviews can reveal:

• communication;
• leadership;
• bullying;
• homework;
• school culture;
• teacher stability.

But they are not a representative survey.

Look for repeated themes across several years.

Ignore comments that tell you only:

“Best school ever!”

or:

“Worst school ever!”

Look for specific experiences that you can verify.

A practical next step

The best school comparison does not produce one winner.

It produces a clear explanation of the differences.

Compare:

academics, growth, attendance, class size, staffing, support, special education, climate, opportunity, demographics, fit and direction.

Then choose the three differences that matter most to your family.

A school rating is useful shorthand.

It should not be allowed to make the decision for you.
