School Culture
& Climate Toolkit

Gruenert and Whitaker offer a striking insight: a school's culture is 'the greatest resistance a leader will ever face' — a powerful, invisible force that exists only in people's minds and that can quietly defeat any improvement effort. That's why the culture/climate distinction is so practical: you can shift climate relatively quickly (a warmer tone, a good week, a morale boost), but changing culture — the deep 'how we do things here' — takes years of consistent effort. 'It is not until we understand culture that we are able to change it.' Know what you're working with, and be patient with the deep work.

A large body of research confirms that positive school climate is associated with higher achievement, better student mental health, less bullying, higher engagement, and better graduation rates — and that it benefits staff too, through greater commitment, collegiality, and retention. The reverse is just as true: a negative or toxic climate drives absenteeism, behavior problems, lower achievement, and staff burnout. Because leaders affect student outcomes largely indirectly — through the culture and conditions they create — tending to culture and climate is not a distraction from the 'real work' of a school. It is much of the real work.

Research paints a clear picture of the difference. In a healthy culture, there's a strong sense of community and care, teachers feel responsible for student learning, staff believe in their collective ability to succeed, expectations are high, and collaboration is the norm. In a toxic culture, there's no clear shared purpose, staff blame students for poor outcomes, norms reinforce inaction, collaboration is discouraged, relationships are conflictual, and staff doubt students can succeed. Most schools sit somewhere between — and the elements above are what to build toward. Nearly every one is something a school can deliberately strengthen.

The four widely used dimensions of school climate are safety (physical and emotional), relationships (respect, support, and connection), teaching and learning (high expectations and academic support), and the institutional environment (the physical space and organization). That last one is often underestimated — but the state of the building, how welcoming and organized it feels, genuinely affects whether students and staff feel comfortable and connected. Assessing climate means looking honestly at all four, from the perspective of everyone in the building (§06).

A school's culture isn't built by mission statements or assemblies — it's built, day by day, by what its leader consistently models (your own behavior is the loudest message), notices and celebrates (what gets recognized gets repeated), and tolerates (what you let slide becomes the new normal). Every interaction sends a signal about 'how we do things here.' This is both a responsibility and an opportunity: you have more influence over your school's culture than anyone — so wield it intentionally. The culture you get, over time, is the one you build through a thousand small choices.

Safety is foundational: a student who feels physically or emotionally unsafe cannot focus on learning, and a staff member who feels unsafe to speak up or be themselves won't fully contribute. Safety means both freedom from physical harm and the emotional safety to take intellectual risks, make mistakes, be yourself, and belong without fear of ridicule or exclusion. Clear and fair norms, strong bullying prevention (see our Bullying & Online Safety toolkit), and a predictable, respectful environment build this foundation — for students and adults alike. Everything else in a positive climate rests on it.

When people — students and staff — feel they genuinely belong, that they're seen, valued, and part of the community, they engage more, try harder, treat others better, and stay. When they don't, disengagement, behavior problems, and turnover follow. Building belonging isn't a program; it's making sure every person in the building is known and valued, that no one is invisible or excluded, and that the environment genuinely welcomes all. It's the emotional heart of a positive culture — and a powerful, research-backed lever for improving outcomes. See our Student Engagement and Student Mental Health toolkits.

At its core, school climate is about healthy, positive, connected relationships — often called the ultimate remedy for bullying and the foundation of belonging, safety, and engagement. Every dimension of culture ultimately runs through relationships: how students treat each other, whether teachers know and believe in their students, whether staff support one another, and whether families feel partnered with. Investing in relationships — creating time and structures for them, and modeling them yourself — isn't separate from improving a school; it's the most direct way to do it.

One of the most important insights in school culture work: the way the adults in a building treat each other and their work shapes everything students experience. A staff that collaborates, supports one another, communicates openly, and believes in its collective ability creates a fundamentally different school than one riddled with isolation, cliques, negativity, and conflict — no matter what's on the walls. Research shows that when educators feel supported by administration and peers, they're more committed and collegial, and their students do better. Building a healthy adult culture isn't separate from serving students — it's how you serve them. See our Teacher Wellbeing toolkit.

Landmark research (Bryk and Schneider's 'Trust in Schools') found relational trust to be a powerful predictor of school improvement. And psychological safety — the shared sense that it's safe to speak honestly, disagree, admit a mistake, or try something new without being humiliated or punished — is what allows a staff to learn and improve together. Where trust and safety are high, people are candid, collaborative, and willing to grow; where they're low, people go silent, protect themselves, and stagnate. Both are built slowly, through consistent respect and integrity, and both are essential to any real change.

A school's culture isn't only created by adults; students shape it powerfully through their peer norms, relationships, and the tone they set with one another. That means students should be partners in building culture, not just subjects of it. Giving students genuine voice — a real say in the school, leadership opportunities, and a channel to share their experience — does two things: it improves the culture (students see problems adults miss), and it deepens belonging and ownership (people care for what they help create). A school that listens to and involves its students builds a stronger, more authentic culture.

Culture experts Peterson and Deal emphasize the power of a school's symbolic life — its traditions, rituals, ceremonies, stories, and celebrations. These aren't trivial; they're how a community expresses and reinforces what it values, builds shared identity, and creates belonging. A meaningful tradition, a celebration of the right things, a story told and retold, genuine recognition of students and staff — these shape culture in ways memos never will. Be intentional about the rituals and celebrations of your school: they're one of the most powerful (and joyful) tools for building the culture you want.

Research on school discipline points toward an authoritative approach — combining high warmth and support with high, clearly communicated expectations — as associated with lower bullying, fewer suspensions, and a safer climate, in contrast to purely punitive or 'zero-tolerance' approaches. How a school handles behavior sends a loud message about its culture: whether it values relationships and repair or just compliance and punishment, whether it's consistent and fair or arbitrary. Building a discipline culture that is firm, fair, relational, and focused on teaching (not just punishing) strengthens safety, trust, and belonging all at once.

A toxic school culture — marked by blame, negativity, isolation, low expectations, and resistance — is real, damaging, and, crucially, changeable. But turnaround doesn't happen through a new slogan or a mandate; it happens slowly, through patient, deliberate work. Start by naming the reality honestly (denial helps no one), rebuild trust and relationships as the foundation, model the culture you want relentlessly, create early wins that show change is possible, protect and amplify the positive people already there, and address genuinely toxic behavior directly rather than tolerating it. It takes time and courage — but the deep force of culture can be turned toward improvement rather than against it.

A school's culture and climate include how it relates to the families and community it serves — whether the front office is warm or forbidding, whether communication is open and two-way or one-directional, whether families are treated as valued partners or as problems to manage. Families are quick to sense a school's true culture, and their trust (or distrust) becomes part of it. Building a genuinely welcoming, partnership-oriented relationship with families — accessible, respectful, and two-way — strengthens the whole school culture. See our Culturally Responsive Teaching toolkit on authentic family partnership.

The famous line (often attributed to Peter Drucker) captures why culture matters so much: the deepest strategy will fail if the culture works against it. And culture cannot be changed by decree — it's cultivated slowly, through consistent action, modeling, relationships, and the gradual shifting of shared beliefs and norms. The practical path: work on climate (which shifts faster) to build momentum and hope, while patiently reshaping the deeper culture over years through a thousand consistent choices. Involve the whole community, expect resistance (culture pushes back), and stay the course. Deep, lasting change is slow — and it's the most important work a school does.

Building a positive culture is hard; keeping it is a different, ongoing challenge — cultures can quietly erode when leaders assume the work is done, when relationships and traditions go untended, or when turnover brings in people who never learn 'how we do things here.' Sustaining culture means continually tending it: renewing shared values, protecting relationships and trust, and — crucially — onboarding new staff intentionally into the culture (hiring for fit, welcoming them well, and actively teaching the norms). Every hire and every year either reinforces or dilutes the culture, so treat sustaining it as permanent work, not a finished project.

For assessing and improving climate, the National School Climate Center offers surveys and resources; Search Institute focuses on the relationships that build belonging; and Greater Good grounds it in the science of connection. The foundational books by Gruenert & Whitaker (culture vs. climate) and Peterson & Deal (shaping culture) are worth reading directly.
