Comparing two K-12 schools, explained like you're 5
What a state report card shows, how to compare two public schools measure by measure, and what a report card leaves out. It names and ranks no school and never says where to enroll.
Explain it like I'm 5
A report card is the public page a state publishes about a public school. It is like placing two grocery labels side by side. A number only means something next to the same number for the other school. Private schools have their own information to ask for.
This explains. It does not advise.
Where all four AIs agree is the solid ground. Where they disagree is exactly what to ask each school or its district office. This guide names and ranks no school and never says where to enroll.
Got two report cards? Compare them.
Attach each school's state report card, saved or printed to PDF from the state's report card site (or photos). ChatGPT, Claude, Gemini and Grok check that the two are the same kind of comparison, line up only the printed measures, flag small numbers and missing data, and write questions for each school. Cover your child's name and any notes about the child first, and turn on Private mode to keep the chat out of your history.

What a report card shows
Not good versus bad: what each part is and what to compare, school to school.
Test scores and growth
A state test score shows how tested students did in the listed subject and grade. Growth means how much students' scores changed over time. Check which grades and subjects the state tests, and whether proficiency, meaning meeting the state's expected level, is shown.
What to compare
- Compare the same subject, grade, school year, and tested student group.
- Compare growth only when both cards use the same state measure.
- Check whether both cards show more than one school year.
What can mislead
- A score without the group of students who took the test lacks important context.
- A single year shown alone can hide change over time.
- Test results do not describe every part of school learning.
Student groups and small numbers
A report card can split results by student group, meaning students who share a reported characteristic. This can show differences between groups. When a group is too small to report, its result may be withheld.
What to compare
- Compare the same student group, measure, grade, subject, and school year.
- Check whether both cards report the group or withhold its result.
- Read each card's notes about missing group results.
What can mislead
- A withheld result is not a score of zero or proof that no students are in the group.
- Different student-group definitions may not match.
- A schoolwide result can hide differences between groups.
Attendance and graduation
Attendance shows how often students are present. Chronic absence means missing school often under the state's definition. For high schools, graduation shows how many students finish high school under the state's counting method.
What to compare
- Compare the same attendance measure and school year.
- Compare graduation only for schools serving high school grades.
- Check whether attendance and graduation are also shown by student group.
What can mislead
- States may define attendance and chronic absence differently.
- Graduation measures can follow a class that started earlier, rather than today's students.
- A missing graduation result may simply mean the school has no high school grades.
Teachers and staffing
This part may show teacher experience, credentials, qualifications, and whether teachers teach subjects they are prepared for. It may also describe other staff and staffing levels. The terms and measures depend on the state.
What to compare
- Compare the same teacher experience or qualification measure.
- Compare staffing information for the same school year.
- Check whether staffing figures describe the school or a wider district.
What can mislead
- Experience and credentials do not measure every part of teaching or classroom life.
- Different labels may count different jobs or qualifications.
- One year's staffing can change when people join or leave.
Funding and spending
This part may show money spent for the school or for each student, and may separate sources and types of costs. The report card may explain how staff costs, other costs, and shared costs are counted. Those definitions matter when comparing amounts.
What to compare
- Compare the same school year and spending definition.
- Check whether both cards include the same funding sources.
- See whether school costs and shared district costs are counted in the same way.
What can mislead
- Spending figures can count shared costs differently.
- An amount alone does not show which services it paid for.
- A single year can include unusual costs or grants.
Ratings and labels
A rating or label is a summary the state gives a school. Each state builds its own rating system, choosing its measures and methods. Read the state's explanation and the separate measures behind the summary.
What to compare
- Compare ratings only for public schools in the same state and school year.
- Read which measures make up each rating or label.
- Compare the underlying measures, not only the summary label.
What can mislead
- A rating system that differs by state makes cross-state labels unlike one another.
- A summary label can hide strengths and weaknesses in separate measures.
- Rating methods can change, so a single year shown alone may mislead.
Rules to know
- What a state report card must show
- The Elementary and Secondary Education Act, as amended by the Every Student Succeeds Act, requires every state and local school district to publish a report card and make it available on their websites (a district without a website may use another format). The Department of Education's parent guide says it must include spending per student for every school and where the money comes from (federal, state and local); results of the annual statewide tests in reading or language arts, math and science, and the share of students taking them; graduation rates within four years; how the state's system rates schools; suspensions, expulsions and chronic absenteeism; and teacher qualifications.

- State tests and NAEP
- The National Center for Education Statistics says most state tests measure student performance on the state's own curriculum standards, and that state tests do not provide comparisons of results with other states or the nation. NAEP is the only assessment that allows comparison of results from one state with another. It adds that proficiency on a state test does not have the same meaning as Proficient on the NAEP achievement levels, because the criteria are different.

- The public school search
- The National Center for Education Statistics' Search for Public Schools looks up public schools and districts using Common Core of Data (CCD) public school data for the 2024-2025 and 2025-2026 school years. It says a school's inclusion in or exclusion from the search does not endorse it and should not be used to infer its accreditation status.

How to compare two schools, step by step
- Make sure both public schools are in the same state, serve the same grade levels, and show the same school year.
- Compare the measures one at a time, using matching subjects, grades, definitions, and years.
- Compare the results for each student group, and note any group too small to report.
- Think about what a report card leaves out, such as programs, how a class feels, and the commute.
Common mistakes
- Treating one test score as the whole picture ignores growth, attendance, staffing, spending, and other information.
- Comparing ratings across states misleads because each state builds its own rating system.
- Reading a score without its tested student group hides whose results the number describes.
- Treating a withheld small-group result as poor performance or no students misreads the report.
- Using a single year alone can hide changes over time.
- Assuming report cards cover private schools is mistaken because private schools have separate information to request.
Questions to ask each school or district
Ask each school or its district office.
- Which grades and subjects does this report card test?
- How does the school or district office calculate growth and chronic absence?
- Which student groups were too small to report, and what does that mean here?
- How does the school or district office count staffing and spending?
- What programs and daily experiences are not shown on the report card?
- What information does the private school provide, since public report cards do not cover it?
