What Your PLCs Should Actually Be Working On
The most effective PLC meetings share one quality: the team works on something specific enough to force an instructional decision. According to a 2014 survey of more than 1,300 teachers and school leaders conducted by the Boston Consulting Group for the Bill & Melinda Gates Foundation (“Teachers Know Best”), just 29 percent of teachers said they were satisfied with the professional development they received. The model that Richard DuFour called “our best hope for sustained, substantive school improvement” has, in many schools, become 45 minutes of administrative updates and vague discussion about student data. The gap between the model and the reality is almost always a focus problem, not a structure problem: it comes down to what the team chooses to work on.
The problem is rarely the schedule. Most schools have the time blocked, the teams assigned, and the norms posted on the wall. The problem is what happens inside those meetings. When PLC topics default to logistics, generic data review, or whatever came up that week, teachers leave without anything concrete to try in their classrooms. The research on effective PLCs points in a specific direction: the topics that change instruction are the ones that connect collaborative analysis to individual classroom action.
Why Don’t Most PLC Topics Change Practice?
Thomas Levine, writing in Learning Forward’s The Learning Professional, identified five challenges that undermine PLCs: incoherence, insularity, unequal participation, congeniality, and privacy. These are all real. But they share a common root: the PLC is not focused on a topic that demands genuine instructional thinking.
When the agenda is “review last week’s assessment data,” the conversation often stays at the surface. Teachers look at numbers, identify which students scored low, and move on. What’s missing is the instructional question: what did we teach, how did we teach it, and what should we change about our teaching based on what students showed us?
Vescio, Ross, and Adams reviewed 11 studies on PLCs published in Teaching and Teacher Education and found that effective PLCs shared four characteristics: open collaboration, a focus on student learning, teacher authority over their own learning, and continuous improvement. Eight of the 11 studies showed positive effects on student achievement. The common thread was that successful PLCs made teaching more student-centered over time, with teachers adjusting their classroom practices based on what they learned together.
The PLC topics that produced these results were not about running the meeting better. They were about asking harder questions about instruction.
What Are the Four Questions That Drive Instructional Change?
DuFour’s (2007) PLC framework centers on four questions that every team should revisit regularly:
- What do we want students to learn?
- How will we know if they’ve learned it?
- What will we do if they haven’t learned it?
- What will we do if they already know it?
These questions define the purpose of a PLC. The specific topics below are organized around these questions, because PLC discussions that don’t connect to at least one of them tend to drift into territory that feels productive but doesn’t change what happens in classrooms.
What Should Effective PLCs Focus On?
Unpacking What Mastery Looks Like (Question 1)
Before teachers can align their instruction, they need a shared picture of what students should be able to do. This is different from reviewing standards. It means looking at an upcoming unit and collectively defining what mastery looks like in student work.
A concrete PLC session: each teacher brings a sample of what they consider mastery-level student work for the current unit. The team compares samples, discusses differences in expectations, and agrees on a common standard. Teachers who have done this consistently report that it surfaces gaps in their own understanding of the content and forces clarity about what they’re actually teaching toward.
This topic works because it produces something teachers take back to the classroom: a clearer target.
Analyzing Student Errors, Not Just Scores (Question 2)
Data review is the default PLC discussion topic in many schools, and it is usually the least productive. Looking at a spreadsheet of test scores tells you which students struggled. It does not tell you why.
A more productive version: bring the actual student work, not the scores. Identify the three most common errors or misconceptions. Discuss what those errors reveal about how the concept was taught, not just how the students performed. Steve Ventura, author of Engaged Instruction, emphasized in a conversation with Edthena that teachers should leave PLC time with “new knowledge about teaching and learning” and that the team should be “sensitively challenging current thinking and practice.”
When PLCs analyze errors rather than scores, the conversation shifts from “these students need reteaching” to “our instruction created this misconception, and here’s what we should change.” That is the shift from data review to instructional analysis.
Comparing How We Teach the Same Concept (Questions 1 and 3)
One of the most powerful PLC activities is having each teacher briefly explain or demonstrate how they introduce the same concept. Not a full lesson plan review, but a five-minute walkthrough of the approach: “Here’s how I set up the problem. Here’s the example I use. Here’s where students usually get stuck.”
This surfaces variation that teachers rarely see otherwise. One teacher’s approach to introducing fractions might emphasize visual models while another jumps to procedures. Neither is wrong, but comparing them reveals options. Teachers can borrow techniques from each other and test them in their own classrooms.
The instructional change: teachers leave with a specific alternative approach to try with their students next week.
Designing Interventions That Change the Teaching, Not Just the Grouping (Question 3)
Many PLC conversations about intervention focus on logistics: who gets pulled for small group, when the reteaching happens, which students need extra time. These are necessary but not sufficient.
The more productive question is: what will the reteaching actually look like, and how will it differ from the original instruction? If a student didn’t learn a concept from a lecture the first time, pulling them for a smaller lecture is not an intervention. It is the same instruction at lower volume.
A strong PLC session on intervention asks: “For the students who didn’t master this, what did our original instruction miss? What different approach might reach them?” This requires teachers to question their own methods, which is why it takes trust and a team culture that treats instructional problems as shared challenges rather than individual failures.
Planning Pre-Assessments That Reveal What Students Already Know (Question 4)
DuFour’s fourth question is the one most PLCs skip entirely. If students already understand the concept, what do we do? Without a pre-assessment, teachers don’t know which students need extension rather than instruction.
A productive PLC session designs a brief pre-assessment (5 to 10 questions or a short performance task) for an upcoming unit. The team agrees on what “already knows this” looks like and plans what those students will do while others receive instruction. This topic changes classroom practice because it forces differentiation planning before the unit starts, not as an afterthought.
Reviewing Recordings of Practice (All Four Questions)
The single most direct way to connect PLC discussion to classroom change is to look at actual teaching. When a teacher shares a recording of a lesson segment, the team can observe student responses, identify specific instructional moves, and discuss alternatives based on evidence rather than memory.
This is the PLC topic that most directly addresses Vescio, Ross, and Adams’ finding about open collaboration and Levine’s challenge of privacy. It requires trust. But it produces the most concrete instructional feedback because the team is looking at real teaching, not talking about it in the abstract.
Making the Shift
If your PLCs feel unproductive, the issue is probably not the norms, the protocol, or the facilitation. It is what the team is working on. Here is a quick test: after the last PLC meeting, could every teacher on the team name one specific thing they planned to do differently in their classroom? If the answer is no, the focus was too broad, too logistical, or too disconnected from instruction.
Start with one shift. Take the next PLC meeting and replace the data review spreadsheet with actual student work. Ask the team to identify the three most common errors and discuss what those errors reveal about instruction. That conversation, grounded in specific student thinking, is more likely to change what happens in classrooms than any amount of score analysis.
Choosing the right focus is the first half of the work. Sustaining it between meetings is the other half, which we cover in how to make PLCs actually change teaching.

Frequently Asked Questions
What are good topics for PLC meetings?
The most effective PLC discussion topics connect collaborative analysis to individual classroom action. Strong choices include: unpacking what mastery looks like in student work, analyzing common student errors to improve instruction, comparing how different teachers introduce the same concept, designing interventions that change the teaching approach rather than just the grouping, and reviewing recordings of actual classroom practice.
How often should PLCs meet?
Vescio, Ross, and Adams found that continuous learning was one of four characteristics shared by PLCs that improved student achievement. Most effective PLCs meet weekly or biweekly to maintain momentum on instructional changes. Monthly meetings are generally too infrequent to sustain the reflection cycle those improvements require.
Why do PLCs fail to improve instruction?
Thomas Levine identified five common challenges: incoherence (no connection to school goals), insularity (teams that don’t look beyond their own practice), unequal participation, congeniality (avoiding honest feedback), and privacy (reluctance to share practice). At the root, most PLC failures come from topics that don’t require genuine instructional thinking, leaving teachers without anything concrete to try.
What is the DuFour PLC model?
Richard DuFour’s PLC framework (2007) centers on four questions: What do we want students to learn? How will we know if they’ve learned it? What will we do if they haven’t? What will we do if they already know it? Schools that use these questions as the basis for collaborative work consistently show stronger instructional alignment than those that don’t.
What to discuss in PLC meetings when data review isn’t working?
Replace the spreadsheet with actual student work. Have teachers bring examples of the three most common student errors from a recent assessment. Discuss what those errors reveal about how the concept was taught, not just how students performed. This shifts the conversation from identifying struggling students to improving the instruction they receive.
