Across the country, math performance remains stubbornly flat or declining. District leaders feel immense pressure to reverse these trends, especially as postpandemic recovery slows, and achievement gaps widen. In many places, the instinct is to focus on curriculum — upgrading materials, adopting new programs or layering on additional tools.
After nearly a decade working with districts across New Hampshire, and years prior as a curriculum director, I’ve learned an important truth:
Curriculum alone cannot close math gaps. Instruction closes gaps. And instruction improves when teachers have access to high-quality, research-based professional learning grounded in how students actually learn mathematics.
The question for district leaders is no longer whether math professional learning matters — it’s what kind actually moves the needle. Here are five essential features to look for when selecting or strengthening math professional learning in your district.
1) It focuses on how students learn — not just what the curriculum teaches
Many districts mistake curriculum training for professional learning. When teachers learn only the mechanics, like lesson components, unit assessments and dashboards, they gain procedural fluency, not pedagogical depth.
High-quality math professional learning keeps student thinking at the center. It builds teachers’ understanding of learning progressions, common misconceptions, and how to read student work as evidence of reasoning, enabling them to adjust instruction in real time.
In student-centered, competency-based systems, this is non-negotiable. When teachers see how concepts develop, they shift from delivering lessons to guiding thinking, turning daily instruction into formative assessment and positioning students as active mathematicians.
2) It strengthens teacher confidence — especially in the early grades
Elementary teachers, through no fault of their own, often feel less confident in math instruction. Many were never taught math conceptually themselves, and most pre-service programs emphasize literacy far more than numeracy. As a result, even deeply committed educators may avoid certain concepts or lean heavily on rote procedures.
Effective professional learning builds both confidence and content knowledge. Confidence matters: when teachers feel secure, they’re more willing to take instructional risks, ask sharper questions, and invite productive struggle — creating the space students need to do the intellectual heavy lifting.
3) It provides a complete picture of the learning trajectory — not isolated skills
Math learning is cumulative and interconnected. A superficial understanding of fractions in grade 4 can resurface as a significant barrier to proportional reasoning in grade 7. A shaky foundation in additive reasoning can undermine algebra years later. Yet many instructional materials treat standards as discrete lessons rather than steps on a developmental pathway.
High-impact math professional learning:
- Illuminates the vertical progression of key concepts from early elementary through algebra and beyond
- Helps teachers see how early misconceptions grow into bigger obstacles if left unaddressed
- Identifies “leveraging standards” that unlock future learning
- Supports teachers in using ongoing diagnostic assessment — not just end-of-unit tests — to understand where students are on the trajectory
When teachers see the trajectory clearly, they stop feeling pressured to “cover everything” and instead focus on what matters most. Instruction becomes more targeted, feedback becomes more meaningful, and reporting practices become more accurate over time.
4) It builds collaborative habits that sustain improvement over time
Even the strongest professional learning loses power if it exists as a one-time event or a stand-alone workshop. Improving math instruction and sustaining gains require structures that support teachers in routinely discussing student thinking, not just pacing, grading, or test preparation.
The best professional learning models build a culture of collaboration by:
- Creating structured PLC routines that focus on math reasoning
- Using real student work as the anchor for team discussions
- Normalizing conversations about how students are thinking, not just whether answers are correct
- Supporting classroom-based labs, co-teaching, or peer observation focused on student discourse and sense-making
These habits change instructional culture. Teachers begin asking different questions: What does this student’s work reveal about their understanding? Why might they be thinking this way? What is the next step in the learning progression for this learner?
5) It is grounded in research, evidence, and alignment with district priorities
Districts deserve professional learning grounded in evidence and aligned with their local Portrait of a Graduate and competency-based priorities. With so many initiatives competing for time and resources, leaders should prioritize programs that:
- Have rigorous external evaluations
- Hold strong ESSA evidence ratings
- Demonstrate measurable gains in student reasoning and problem-solving
- Show growth in teachers’ diagnostic skills and pedagogical content knowledge
- Integrate naturally with existing systems — grading, reporting, interventions and flexible pathways
One example is the OGAP (Ongoing Assessment Project) professional learning system, which helps teachers use learning progressions, student work, and research-based frameworks to make daily instructional decisions. When professional learning is evidence-based and system-aligned, districts aren’t just “doing another PD initiative.” They’re investing in the instructional engine that powers a student-centered, competency-based math system.
A path forward for districts
Improving math achievement requires more than updated materials. It requires systems that:
- Empower teachers with deep knowledge of how students learn math
- Provide clear learning progressions and priority standards
- Embed ongoing diagnostic assessment into classroom practice
- Cultivate collaborative cultures focused on student thinking
- Align professional learning with a broader vision for competency-based, student-centered education
If we want different results in mathematics, we must invest in professional learning that reshapes how teachers see math, how they see their students, and how students see themselves: as capable, confident mathematical thinkers whose growth can be seen, named, and celebrated over time.
