What Makes a Good School? 7 Things That Matter More Than Rankings

We rate schools for a living. Our database covers 114,000+ public schools with test scores, growth metrics, equity data, and student-teacher ratios. We believe in data.

But we also believe in honesty: ratings don’t capture everything that makes a school good.

A school rated 6/10 on our system might be the perfect place for your child. A school rated 9/10 might be the wrong fit. The data tells you where to look. These seven factors tell you what to look for when you get there.

1. Teacher Quality and Stability

This is the single most important factor in your child’s educational experience, and it’s the one no rating system measures well.

What the research says: A student with a highly effective teacher gains roughly 1.5 years of learning in a single year, compared to 0.5 years with a weak teacher. Over three consecutive years, the difference between having strong versus weak teachers is equivalent to an entire grade level of achievement. The effect is larger than class size, curriculum choice, or school funding.

What to look for:

• Teacher retention. Ask the principal: “How many teachers left last year?” High turnover (more than 15-20% annually) is a red flag. Schools where teachers stay for 5+ years tend to have stronger cultures, better institutional knowledge, and more consistent instruction.
• Experience distribution. A school where most teachers are in their first three years is in a fundamentally different place than one where the average is 10+ years. Both can be effective, but the risks differ.
• Professional development. Ask what teachers are currently learning. Strong schools invest in ongoing training. Weak schools treat professional development as a compliance checkbox.

Why ratings miss this: No federal dataset captures teacher quality directly. We can measure student-teacher ratios, but not whether those teachers are passionate, skilled, or staying.

2. School Culture and Climate

School culture is the thing you feel the moment you walk through the front door, and it has an outsized effect on whether your child thrives.

What it actually means:

• How students talk to each other in the hallway
• How adults respond when a child is struggling (with patience or with frustration)
• Whether the office staff welcomes you or treats you like an interruption
• Whether student work is displayed with pride or the walls are bare
• The noise level in the cafeteria — chaotic or manageable
• Whether students seem engaged or checked out during lessons

What to look for:

• Behavioral approach. Schools using restorative practices or positive behavioral supports tend to have healthier cultures than those relying primarily on suspensions and detentions. Ask about the school’s discipline philosophy.
• Student voice. Do students have ways to provide input? Student councils, surveys, or advisory periods suggest the school values its students’ perspectives.
• Parent feedback. Talk to at least three current parents. Ask: “Does your child want to go to school in the morning?” This simple question reveals more about culture than any metric.

Why ratings miss this: Culture is subjective and local. It can change when a principal leaves. No dataset captures it at scale. The only way to assess it is to visit.

3. Principal Leadership

A strong principal is the difference between a school that coasts and one that improves. Research consistently identifies principal quality as the second-most-important school-level factor (after teacher quality) in student outcomes.

What effective principals do:

• Set clear academic expectations and follow through. They know the school’s data, visit classrooms regularly, and hold teachers accountable for results.
• Create a positive culture. They know students’ names. They’re visible in hallways and at events. They model the behavior they expect.
• Retain good teachers. The best indicator of a strong principal is that teachers want to work there. Ask teachers (not just the principal) whether they’d choose to work at this school again.
• Manage operations. A school where buses are chronically late, the building is falling apart, or basic communications don’t go out has a leadership problem, not just a logistics problem.

Red flags:

• Principal has been at the school less than two years AND is the third principal in five years. Leadership instability hurts everyone.
• Principal can’t articulate specific academic goals for the current year. “We want all students to succeed” is not a goal.
• Teachers seem afraid to speak openly during your visit. That tells you about the management style.

Why ratings miss this: No national dataset tracks principal quality. School-level performance data reflects principal impact indirectly (through test score trends and growth metrics), but with a significant time lag.

4. How the School Handles Struggling Students

Every school has students who fall behind. What separates good schools from mediocre ones is the system for catching and supporting those students.

What to look for:

• Early identification. Does the school assess students regularly (every 6-8 weeks) to catch problems early? Or does the school wait for annual test results, by which time a full year has been lost?
• Tiered intervention. Strong schools use a Response to Intervention (RTI) or Multi-Tiered System of Supports (MTSS) framework. Students who fall behind get progressively more intensive support: small-group instruction, then one-on-one tutoring, then formal evaluation for special services if needed.
• Reading intervention specifically. If a child can’t read at grade level by the end of third grade, the long-term consequences are severe. Ask what the school does when a first-grader isn’t learning to read on schedule. “We monitor and wait” is not an acceptable answer.
• Special education quality. If your child has or might need an IEP, ask about the school’s approach. Are special education students included in general education classrooms with support? Or are they segregated in separate classrooms? Research strongly favors inclusive models for most students.

Why this matters more than test scores: A school with 75% proficiency might have a strong intervention system catching the other 25%. A school with 85% proficiency might be letting the bottom 15% languish. The overall number doesn’t tell you which school you’d want if your child were in the struggling group.

5. Curriculum Coherence

Most parents don’t think about curriculum, but it shapes your child’s daily experience more than almost any other factor.

What “coherent curriculum” means:

• Teachers across grade levels follow a coordinated sequence. What students learn in 3rd grade builds directly on 2nd grade and prepares them for 4th.
• The school has chosen specific, high-quality instructional materials — not just “whatever the teacher finds online.”
• Teachers use the curriculum as designed, rather than supplementing it ad hoc with worksheets and YouTube videos.

Why it matters:

• Students who transfer between schools within the same district should pick up where they left off. If every teacher uses different materials, there’s no continuity.
• Research shows that curriculum quality has a larger effect on student outcomes than teacher experience level. A good teacher with a weak curriculum underperforms a good teacher with a strong curriculum.

Questions to ask:

• “What reading and math programs do you use?” If the school can name them and explain why they were chosen, that’s a good sign.
• “Do all teachers at the same grade level teach the same units at the same time?” Alignment suggests coordination.
• “How was the curriculum chosen?” Schools that adopted their materials through a deliberate, evidence-based process are more intentional than those that inherited whatever was there before.

6. Enrichment and the Whole Child

Test scores measure math and reading. Your child’s education includes a lot more than math and reading.

What to look for:

• Arts. Does the school have dedicated art and music teachers, or are those programs the first to be cut when budgets tighten? Schools with robust arts programs tend to have stronger student engagement.
• Physical activity. How much recess do students get? (Anything less than 20 minutes daily for elementary students is concerning.) Is PE taught by a specialist or handled by the classroom teacher?
• Science and social studies. In many schools, especially in lower grades, these subjects have been crowded out by reading and math test prep. Ask how much instructional time is devoted to science and social studies weekly.
• Social-emotional learning. Does the school explicitly teach students how to manage emotions, resolve conflicts, and build relationships? Programs like Second Step, RULER, or Responsive Classroom are evidence-based approaches.
• Extracurriculars. What’s available beyond the school day? Clubs, sports, tutoring, enrichment? The breadth of offerings indicates how invested the school is in the whole child.

Why this matters: Parents who focus exclusively on test scores often end up in schools that have narrowed their curriculum to maximize test performance. Their children score well on state tests but miss out on experiences that develop creativity, critical thinking, physical health, and social skills.

7. Community and Family Engagement

Schools don’t operate in isolation. The relationship between a school and its community shapes everything from funding to culture.

What strong engagement looks like:

• Regular, useful communication. Weekly or biweekly updates from teachers about what’s being taught and how families can support learning at home. Not just permission slips and fundraising requests.
• Meaningful parent roles. Parents are invited into decision-making, not just volunteering. School improvement teams, PTA leadership, curriculum committees.
• Accessibility. The school communicates in the languages families speak. Events are held at times working parents can attend. The school feels welcoming to all families, not just the ones who can volunteer during school hours.
• Community partnerships. Strong schools connect with local organizations for mentoring, tutoring, after-school programs, and career exposure.

Warning signs:

• The school’s website hasn’t been updated in months
• You can’t reach anyone at the front office by phone
• There’s no PTA, or the PTA is run by three people who’ve been doing it for a decade with no new participation
• Communication is one-directional (school to parents) with no mechanism for parent input

Putting It All Together

Here’s a practical framework for evaluating a school that goes beyond the number:

Step 1: Start with data. Use School Scout’s ratings to build a shortlist of 3-5 schools that perform well academically. This eliminates schools with fundamental academic problems and focuses your deeper research.

Step 2: Visit each school. Use our school tour question guide to assess culture, leadership, and enrichment. Pay attention to how the school feels, not just what the principal says.

Step 3: Talk to parents. Ask current parents about the seven factors above. Their lived experience is the most reliable source of information about day-to-day quality.

Step 4: Evaluate fit. Does this school match your child’s learning style? Your family’s values? Your logistical needs? The “best” school is the one where your child will be known, supported, and challenged.

Step 5: Trust the process. If you’ve done the research — data, visits, conversations — trust your judgment. There is no objectively perfect school. There’s the school that’s right for your child right now.

What School Scout Measures (and What We Don’t)

We’re transparent about the limits of our data:

What We Measure	What We Can’t Measure
Test score proficiency	Teacher quality
Year-over-year growth	School culture
Student-teacher ratios	Principal leadership
Equity across demographics	Curriculum quality
Chronic absenteeism	Enrichment programs
Enrollment and demographics	Parent satisfaction

Our ratings are a powerful starting point. They help you find schools worth investigating. But the final decision should always include what you see, hear, and feel when you walk through the door.
