compare public school ratings in neighborhoods of a city

Neighborhood school ratings can differ for several reasons, including the households around each school, budgets, and enrollment patterns, though a rating alone does not show which factor matters most. The GreatSchools Rating is a 1-10 score that compares a school with other public schools in its state, so it describes where a school stands relative to peers, not how much the school itself adds to a student’s learning. Three factors are often examined alongside that position: household income, local funding, and enrollment mix. A rating alone cannot show how much each one contributes.

Why do school ratings differ by neighborhood?

Household income and student background

Ratings measure test results and progress. Student background may be one factor behind rating differences, but a rating alone cannot show how much of a gap comes from teaching and how much from other factors. A high rating in one area does not prove that its school teaches better than a lower-rated school nearby.

To test this, collect the median household income for the attendance area of each school from public census income tables, then place those figures next to the ratings. A consistent pattern across several schools shows an association between income and rating, but it does not by itself show what causes it.

Local funding and district budgets

School budgets pay for staff, class sizes, and programs. A larger local share of revenue can tie spending more closely to the resources of the area, while a larger state share can make funding less dependent on the neighborhood. How far this holds varies by state and district.

Find the district’s published budget and identify the split between local and state sources. Then compare how each school’s program offerings and staffing line up with its rating. This shows whether funding differences are visible in the school’s day-to-day resources.

Enrollment mix and student mobility

A rating reflects the students whose results are included, and a changing student body can affect how well it describes the school. High student mobility, where pupils frequently enter or leave, means the rated group may differ from the group enrolled at the start of the year.

Review enrollment figures for several years. Sharp shifts in enrollment size or in the composition of the student body mean the rating may describe a changing population, so read it with caution.

What does a GreatSchools rating measure?

The GreatSchools Rating is a single score from 1 to 10 that summarizes a school’s performance across up to three themed ratings. The overall score is a weighted average of those themed ratings, so a school’s number depends on which themes it has data for. Each school is compared with other public schools in the same state, which means a band describes standing within that state group.

The three themed ratings

• Student Progress: measures growth over time. When growth data is missing, the Academic Progress proxy is used in its place.
• Test Score: reflects the school’s test results.
• College Readiness: applies to high schools only. Elementary and middle schools are not scored on this theme.

Alternative schools are not rated at all, so a neighborhood with several alternative options may show fewer scored schools than expected. A high school’s overall rating can include all three themes, while an elementary or middle school’s rating can include only Student Progress and Test Score, depending on the data available. Two schools with the same number may therefore rest on different mixes of themes.

Band cutoffs

When comparing schools across neighborhoods, use the band first and the exact number second. Because the bands are tied to each state, a band label is more reliable for comparing schools within one state than for comparing schools across state lines.

How do you compare schools within a city?

To rank public schools inside one city, group them by level match first, then compare them using the same data year and the same rating components. Schools in the same city share a state peer group, so comparisons are more consistent, but only if the schools are of the same type and measured the same way.

Step 1: Match schools by level

Sort candidates into elementary, middle and high schools before comparing any figures.

Remove alternative schools from the list rather than assigning them a low position.

Step 2: Use same-year data for every school

Check the data year shown on each profile and compare only schools that share it. Mixing years makes it impossible to tell whether a change reflects a difference between schools or a different testing year. If a school’s figures come from another year, keep it out of the ranking until they match, or flag the gap beside its name.

Step 3: Read growth data alongside test scores

For each school, compare the Student Progress rating with the Test Score rating. Test scores describe performance at a point in time, while growth data shows change over time. A school with strong test scores but weak progress, or the reverse, should be read as a different profile, not averaged into a single position. Record which measure sits behind each overall figure before ranking.

Step 4: Map results to the rating bands

Assign each school to its GreatSchools band, then compare schools within each level group, not across levels. Confirm that each band agrees with the underlying test and progress ratings before drawing conclusions.

Do attendance zones decide which school a home gets?

Often, but not always. An attendance zone, also called an attendance boundary, is the area whose residents are assigned by default to a specific public school. The home’s location determines the assigned school, so two homes on the same street can be assigned to different schools if they sit on opposite sides of a boundary line. The National Center for Education Statistics (NCES) publishes boundary data through the School Attendance Boundary Survey (SABS).

The dataset covers only two school years. A boundary file therefore shows the zones that existed in 2013-2014 or 2015-2016, and those zones may differ from current assignments. Check the school year of any boundary file before using it to compare neighborhoods today.

The zone rule has exceptions. Open enrollment policies allow families to request a school outside their assigned zone. Magnet programs admit students through an application process rather than by address. A school’s zone therefore describes its default intake, not its full student body. When comparing neighborhoods, identify which schools in the zone accept transfers or run magnet programs, because those schools can draw students from outside the boundary.

A boundary file records geography only. It does not confirm that a specific address will receive a seat at the assigned school.

Where can you find official school data?

Official school data for neighborhood comparisons comes from three source types: a federal boundary dataset from the National Center for Education Statistics (NCES), state education department portals, and third-party rating pages. The federal and state sources are government publications. GreatSchools is a separate organization that compiles and rates public schools, so use its figures as a starting point and check them against state records.

Federal data: NCES School Attendance Boundary Survey

The School Attendance Boundary Survey (SABS) is an experimental collection run by the EDGE program with the Census Bureau and published by NCES.

Because the latest school years covered are 2015-2016, confirm on the NCES website whether a newer release exists before using SABS for current-year comparisons. Shapefiles require GIS software or a mapping tool that can read the format.

State education department report card portals

Each state education department maintains its own school data site, usually labeled a report card portal. These sites are the primary government source for school-level performance and enrollment information within a state. To use one:

• Find your state education department’s official website.
• Look for a “report card,” “school data,” or “accountability” section.
• Search by school name or district, then record the figures and the year they cover.

Report card formats differ from state to state, so field names and metrics will not match across state lines.

GreatSchools school profile and rating pages

GreatSchools publishes a GreatSchools rating on a 1–10 scale for each school profile. Profile pages also list district and school details that help identify a school’s attendance zone.

Are school ratings enough to choose a neighborhood?

A school rating measures school performance. It does not measure the day-to-day cost or convenience of living in an area. A neighborhood choice therefore needs at least three other inputs alongside the GreatSchools Rating: housing prices, travel access, and local services.

The score says nothing about what homes cost nearby, how long the commute is, or whether the households around the school match your own situation.

Housing prices. Property transaction records, such as those kept by local county recorder or assessor offices, show actual sale prices in specific streets and districts. Compare recorded sales of similar property types within the same neighborhoods. Asking prices and recorded sale prices can differ, so the completed transactions are the more reliable reference.

Commute and transit access. Measure the route you would actually take at the hours you would travel. Check the distance from home to the nearest transit stop and the frequency of service on that line. A school with a high rating in a district with a 40-minute commute may cost more time each day than a lower-rated school ten minutes away.

Local services and household makeup. Check what is within walking distance: pharmacies, healthcare, shops, parks, and childcare options. Census-style data on household composition, such as the share of families with children or the share of single-person households, shows whether the neighborhood fits your household’s needs.

Why ratings can’t be compared across states

A GreatSchools Rating is a relative measure. For each measure, the raw result is converted to a percentile against that state’s peers and then mapped to a decile. The final 1–10 number therefore describes a school’s position within its own state’s distribution.

This means two schools with the same score may sit at very different levels of performance. A 7 in one state is not directly comparable to a 7 in another, because each 7 is measured against a different group of peers.

What changes between state peer groups

The percentile depends on the state peer group used as the reference. Each state’s peer group is shaped by:

• State tests: Results come from each state’s own assessments, so a score on one state’s test cannot be placed on the same scale as a score on another state’s test.
• Proficiency standards: Each state sets its own standards for what counts as proficient. A school can rank highly against its peers in a state with lower standards and rank lower in a state with higher ones.
• Student population and school mix: The percentile reflects the schools that exist in that state, so the same raw result can map to a different decile in a different state.

Because these inputs differ, the decile a school receives in State A says nothing about how it would rank in State B.

Neighborhood comparisons across state lines

Neighborhoods that straddle a state border, or metropolitan areas that span two states, are a common trap. A family comparing a school on one side of the line with a school on the other is comparing two different reference groups.

To compare fairly across a state line:

1. Note the state each school is rated against, not only the score.
2. Compare the raw test results or other underlying data where they are published, rather than the composite score.
3. Treat the scores as a within-state signal only, and avoid ranking schools from different states on the same scale.

Frequently asked questions

How is the GreatSchools Rating calculated?

The GreatSchools Rating is a 1–10 score that places a school against other public schools in its state. Each measure is converted to a percentile against state peers and then mapped to deciles, and the overall score is a weighted average of up to three themed ratings.

Can I compare ratings of schools in two different states?

Not directly. Scores from different states sit on separate scales, because each one is measured against that state’s own state peer group. Schools within the same state share that peer group, so comparing them is more consistent, provided they are the same type and measured the same way.

How do I find which school serves a given address?

Look up the attendance zone on your district’s boundary map or through its enrollment office, since assignments can change from year to year. The experimental boundary files covering 2013–2014 and 2015–2016 are too old to confirm current assignments.
