In today’s schools, collaboration is non-negotiable, but unfortunately, it’s not always productive.

Professional learning communities (PLCs) are designed to fix that. When implemented well, PLCs turn “just another meeting” into focused, actionable time that directly improves instruction and student outcomes. But too often, they become routine check-ins with little impact.

So, what separates the high-performing PLCs from the ones just going through the motions?

This guide breaks it down: what a PLC is, what makes it effective, and how to build one that actually drives change. Whether you’re refining an existing PLC or starting from scratch, these insights will help your team make the most of its time together and see results where they matter most: in the classroom.

What is a PLC, really?

A professional learning community (PLC) is a group of educators who meet regularly to collaborate around improving student outcomes. But it’s not just about sharing ideas; it’s about doing the work together: analyzing student data, identifying learning gaps, and designing instructional responses as a team.

Unlike traditional top-down PD or siloed planning time, PLCs are grounded in shared responsibility and continuous improvement.

A good PLC requires collaboration; a great PLC requires clarity, purpose, and progress.

4 reasons PLCs work

When teams of educators are focused, aligned, and data-informed, the results are hard to ignore.

1. Teams improve student learning by identifying what’s working, what’s not, and how to adjust quickly.
2. Teachers feel more supported when they can plan, reflect, and problem-solve together.
3. Instruction becomes more aligned as grade levels and subject teams get on the same page about what success looks like.
4. Meaningful collaboration builds trust, boosts morale, and strengthens school culture.

PLCs work because they turn isolated effort into collective impact.

How do PLCs improve student outcomes?

It’s simple, really: better collaboration leads to better instruction.

PLCs give educators the time, structure, and support to focus on what students need as opposed to what might be next on the pre-set curriculum.

Here’s what that can look like in practice:

• Noticing that students are struggling with fractions across multiple classrooms? PLCs allow teams to dive into the data, identify misconceptions, and adjust instruction together.
• See a group of students exceeding grade-level expectations? PLCs are the perfect space to plan enrichment that keeps them challenged and engaged.

Whether it’s addressing unfinished learning or closing equity gaps, PLCs help schools act smarter, faster, and, most importantly, together.

What are the characteristics of an effective PLC?

Not all PLCs are created equal. The ones that make a real difference usually have a few things in common:

• A clear purpose. Everyone knows the “why,” and the group is focused on student learning.
• Consistent meeting time. Teams meet regularly enough to build momentum. 
• Shared norms. Expectations are clear, whether it’s how data is shared or how decisions are made.
• Real-time data. This is a big one. Teams use unified data from current student work, assessment scores, and attendance patterns – not outdated, disconnected reports.
• Trust and collaboration. Educators feel safe sharing ideas, asking questions, and disagreeing respectfully.

3 steps to get started with a PLC

If you’re starting from scratch, don’t overcomplicate it. High-impact PLCs begin with three simple steps:

1. Establish a shared purpose
   What is your PLC trying to achieve? Maybe it’s improving literacy outcomes, aligning assessments, or better supporting Tier 2 students. Start with a clear, student-centered goal.

2. Build the right team
   Who needs to be at the table? Think beyond grade level or subject area to consider support staff, EL specialists, counselors, or interventionists who bring relevant insights and unique perspectives.

3. Set your meeting norms
   Agree on logistics (how often you’ll meet, where, and for how long) and behavioral norms (how data will be shared, how decisions are made, and how to stay on track). 

3 ways to sustain a PLC

Starting strong is one thing. Sustaining momentum is where most teams struggle. To keep your PLC from losing steam, be sure to:

1. Protect the time. Put meetings on the calendar and treat them like instructional time.
2. Celebrate small wins. When students show growth or an intervention works, name it. Share it. Build on it!
3. Check in regularly. Set aside time for reflection: What’s working? What’s not? What needs to change?

If things feel stuck, revisit your original purpose or re-center around the five PLC questions (see the above section). More often than not, it’s not the team that’s off track; it’s the structure.

Who are the key members of a PLC?

The absolute best PLCs are inclusive and role-diverse. Depending on goals, your PLC might include:

• Grade-level or subject-area teachers
• Instructional coaches
• Special education teachers
• English learner specialists
• School counselors or social workers
• Administrators or deans

To be clear, everyone doesn’t have to attend every meeting, but the right people should be involved at the right time. If you’re discussing interventions, include someone from your MTSS team. If you’re analyzing attendance patterns, bring in your school counselor.

What is the role of edtech in PLCs?

Technology will never replace teachers, and it certainly can’t run a PLC for you, but it can make a huge difference in how efficient and effective your meetings are.

Here’s how edtech tools can support PLCs:

• Centralizing student data so teams don’t waste time digging for reports
• Visualizing performance trends across academics, behavior, and attendance
• Surfacing insights through AI that might have otherwise been overlooked
• Making collaboration easier with shared assessments, student groups, and learning resources

A well-supported PLC should spend its time acting on data, not collecting it.

Real-world examples of PLCs

So far, we’ve covered the what, why, and how of PLCs. But what does this actually look like in schools? Here’s how three districts are using PLCs to drive real collaboration and, most excitingly, real results. 

Wastach County School District, Utah

In Wastach, PLCs are the engine behind instructional growth, teacher support, and a healthy school culture. Each week, collaborative teams meet to review real-time data, identify learning gaps, and develop strategies together. Their superintendent treats PLCs as the heart of the school’s instructional model, where success is measured not just by test scores but by how well students are supported every step of the way.

Hemet Unified School District, California

At Hemet Unified, PLCs are treated like mission-critical work. Every school follows a common PLC protocol, and teams meet regularly during protected planning time to unpack essential standards, review student data, and build targeted action plans. To keep everyone aligned, the district rolled out shared protocols and tapped into resources like Learning By Doing and The Teacher Clarity Playbook. And while not every team started at the same place, leadership took a smart approach: model first, then let teacher leaders take the reins. It’s a system built on trust, support, and a shared goal: helping every student grow.

Monroe School District, Wisconsin

In Monroe, PLCs have been a central part of school culture for over a decade. Every Friday, students are released early so teachers dedicate two hours to deep collaboration. During this time, teams revisit essential questions (What do we want students to learn? How will we know if they’ve learned it?) and analyze common formative assessment data to identify which instructional strategies are working and which need adjusting. Teachers share successes and challenges in real time, refining their approaches week to week. This commitment to continuous improvement has fostered a strong sense of ownership, with departments leading the work and always coming back to one guiding belief: all means all.

4 things teachers should know about PLCs

If you’ve ever left a meeting thinking, “That could’ve been an email,” you’re not alone. But PLCs done right actually give you something back: time to reflect, problem-solve, and plan with people who get it.

Here’s what every teacher considering a PLC should know:

1. PLCs are designed to support you. They’re a space to surface challenges, share ideas, and make instructional decisions as a team.
2. You don’t have to wait for admin. Some of the strongest PLCs start with teachers who see a need and take initiative.
3. It’s okay to bring questions, not answers. PLCs work best when teachers can be honest about what’s not working and work through it together.
4. You don’t have to do it all at once. Start with one shared assessment or collaborative planning session. The momentum will build.

5 things administrators should know about PLCs

Some of the most important work in schools happens in PLCs, but only if leaders create the right conditions.

Here’s how school and district leaders can help PLCs succeed:

1. Start with the “why.” Help your staff understand the purpose of PLCs and how they support student growth and teacher development.
2. Protect the time. Don’t double-book it. Don’t cancel it for assemblies. Make it sacred.
3. Support, don’t supervise. Teachers need to feel ownership, not evaluation. Trust them to use the time well, and give them tools to help.
4. Provide structure. Offer protocols, sample agendas, and professional learning. Not all PLCs will know how to start, and that’s okay.
5. Look out for burnout. If your team is already stretched thin, PLC time shouldn’t  feel like “one more thing.” Find ways to streamline other responsibilities so this time feels purposeful, not piled on.
