As a Special Education Director, I spend a lot of time in two parallel conversations: one about outcomes (How do we know students are learning?) and one about capacity (How do we deliver services when staffing is tight and needs are growing?). The good news is that one of the most powerful levers for improving student learning does not require a new curriculum purchase or a new schedule. It requires sharpening how we use evidence of learning in real time.
In their landmark literature review, Paul Black and Dylan Wiliam (1998) synthesize a wide body of research on classroom formative assessment—what many educators now call “assessment for learning.” Their central finding is straightforward: when teachers and students use frequent feedback to adjust teaching and learning, students make substantial gains. Even better, the gains are often strongest for students who have historically struggled—an equity implication that matters deeply in special education and related services.
What formative assessment is (and what it is not)
Black and Wiliam describe formative assessment broadly as activities by teachers and students that generate information used as feedback to modify teaching and learning. The key phrase is “used as feedback.” If information is collected but not acted upon, it is not functioning formatively.
This distinction matters because many classrooms (and many systems) overemphasize summative practices—grades, end-of-unit tests, benchmark scores—without building the day-to-day routines that help students improve while learning is still underway.
Why this matters for special education and therapy services
Students receiving special education services, speech-language therapy, occupational therapy, or mental health supports often need:
- Clear, measurable learning targets
- Frequent opportunities to practice
- Timely, specific feedback
- Adjustments when progress stalls
Those needs align perfectly with formative assessment. In fact, many therapy models already rely on continuous observation, data collection, and instructional adjustment. The opportunity is to align classroom routines and therapy routines so students experience a coherent feedback system rather than disconnected interventions.
Key research insights highlighted by Black & Wiliam
1) Feedback works—but the type of feedback matters
Across studies, strengthening feedback loops improves learning. However, not all feedback is equal. Feedback is most helpful when it is specific and task-focused—what to do next and how to improve—rather than simply evaluative.
One especially important finding summarized in the review is that grades can undermine the benefits of comments. In Butler’s work (described in the review), students who received comments improved, while students who received grades (even with comments) often declined. For many learners—particularly those who already doubt their ability—grades shift attention from “How do I improve?” to “How do I compare?”
2) Student self-assessment is not optional—it is foundational
A consistent theme is that students are not passive recipients of feedback. For feedback to change learning, students must recognize the gap between where they are and where they need to be, and then take action to close that gap.
That is why self-assessment and peer assessment show promise in multiple studies. When students understand learning goals and criteria for success, they can monitor their own progress and make better choices about effort, strategy, and revision.
3) Formative assessment is not a “small add-on”
Black and Wiliam emphasize that formative assessment is tightly connected to pedagogy. It is hard to “bolt on” a few exit tickets and expect major results if the classroom culture still treats assessment as judgment rather than information.
In practice, this means leaders should look for coherence across:
- Learning intentions and success criteria
- Instructional tasks that reveal thinking (not just recall)
- Teacher questioning and classroom discourse
- Opportunities for revision and re-teaching
- Student ownership through reflection and goal-setting
4) Mastery learning and frequent checks can help—when they drive action
The review discusses mastery learning approaches where students receive regular checks and must reach a high level before moving on. These models can produce strong outcomes, but the mechanism is not the test itself—it is what happens next: corrective instruction, additional practice, alternative strategies, and a belief system that assumes all students can succeed with the right supports.
This has a direct parallel in special education: progress monitoring only helps if it changes instruction, services, or intensity.
What weak formative practice looks like (and why it persists)
Black and Wiliam also summarize research showing that typical classroom assessment practice is often weak. Common issues include:
- Overreliance on recall-level questions and tasks
- Limited peer collaboration or professional critique of assessment items
- Grading dominating feedback
- Norm-referenced comparisons that demotivate struggling learners
- External accountability pressures pushing teachers toward “mini-summatives”
As a district leader, I see this play out when teachers feel trapped between pacing guides, high-stakes testing, and the very real needs of students in front of them. The solution is not to blame educators; it is to design systems that make formative practice feasible, supported, and valued.
Practical moves schools can implement now
Based on the themes in Black and Wiliam’s review, here are actionable steps that work across general education, special education, and related services.
Clarify targets and success criteria
- Post and unpack “what success looks like” in student-friendly language
- Use exemplars and non-exemplars
- In therapy sessions, align goals to classroom demands when appropriate (e.g., vocabulary for science units, writing stamina, self-regulation routines)
Shift feedback from judgment to guidance
- Prioritize comments that describe next steps over scores
- When grades are required, separate the grade from the learning conversation (different day, different channel, or different routine)
- Use feedback that is timely enough to be acted on
Build student self-monitoring routines
- Simple rubrics, checklists, or “traffic light” reflections tied to criteria
- Goal-setting with short cycles (weekly is often realistic)
- Teach students how to use feedback, not just receive it
Use evidence to adjust instruction and services
- Plan “if/then” responses: if data show X, then we will reteach using Y
- In IEP implementation, use progress data to adjust frequency, grouping, or strategy—not just to report progress
- Coordinate with related service providers so classroom and therapy feedback reinforce each other
Where TinyEYE fits in the formative assessment ecosystem
TinyEYE’s online therapy model can strengthen formative practice when it is integrated thoughtfully with school teams. In an environment of therapist staffing shortages, virtual delivery can support continuity and consistency—two conditions that make feedback loops more effective.
To maximize impact, districts can:
- Establish shared goal language between therapists and teachers
- Use consistent data routines (brief, frequent, instructionally relevant)
- Schedule quick collaboration touchpoints so therapy insights inform classroom supports and vice versa
- Focus on student agency: help students understand their goals and track their own progress
When online therapists and educators operate as one coordinated team, formative assessment becomes a shared practice rather than a classroom-only responsibility.
Bottom line
Black and Wiliam’s review remains influential because it connects a simple idea to strong evidence: feedback that is used—by teachers and students—to adapt instruction improves learning. The work also warns us that the details matter. Feedback can motivate or discourage. Grades can dilute learning-focused messages. And students must be active participants, not passive recipients.
For district leaders balancing compliance, parent partnership, and staffing realities, formative assessment is not another initiative to add. It is a way to make what we already do more responsive, more equitable, and more effective.
