What the research says about the practices behind student success

Universal screening can help schools identify students whose learning warrants closer attention, including students whose difficulties may not yet be obvious.

The research does not support treating screening itself as an intervention. Its value is that it can bring a question into view early enough for educators to investigate and respond.

The Institute of Education Sciences recommends universal screening as part of a broader process that includes progress monitoring and targeted instruction. For struggling readers, for example, its guidance combines screening with systematic small-group instruction and continuing review of progress. [5]

That distinction matters to True Progress. A Screener result is evidence, not a diagnosis and not an instructional prescription. Visibility combines assessment with classroom work, educator knowledge, observation, and student and family perspectives to determine what deserves a closer look.

Intervention is more effective when it is directed toward a specific learning need and connected with the student’s wider curriculum.

The evidence for small-group tuition illustrates the point. The Education Endowment Foundation reports an average impact of four additional months of progress and specifically identifies targeting instruction to students’ particular needs as an important feature of effective implementation. [4]

Research on high-impact tutoring reaches a similar conclusion. Effective programs are intensive and individualized, but they also complement rather than replace classroom learning and are aligned with the school curriculum. [3]

Focused Curriculum applies this principle beyond tutoring. Educators identify the knowledge or capability that needs development, establish an appropriate starting point, and build a coherent path toward increasingly demanding work.

Formative Teaching is built around a simple cycle: create opportunities to understand student thinking, interpret what the evidence suggests, respond, and examine what the student does next.

A large independent evaluation of the Embedding Formative Assessment program in 140 schools and approximately 25,000 students found the equivalent of two additional months of progress. [1]

Feedback has an even broader research base. The Education Endowment Foundation estimates an average effect equivalent to six additional months of progress, while emphasizing that effects vary substantially and that some forms of feedback can be ineffective or even harmful. Effective feedback gives students usable information about how to improve rather than merely evaluating their performance. [2]

The implication is not that teachers should constantly change instruction. It is that evidence from learning should be capable of changing what happens next.

Collecting evidence is only useful if educators can interpret it and use it to review their response.

The Institute of Education Sciences describes Data-Based Individualization as an iterative process: implement an evidence-based response, monitor progress, collect additional diagnostic evidence when progress is inadequate, adapt the intervention, and continue monitoring what follows. [6]

That logic is central to Meaningful Data.

Current achievement and progress over time answer different questions. A student may still be working below expectations while making substantial progress. Another may be achieving highly while making little progress. Evidence becomes meaningful when educators can distinguish those situations, consider them alongside classroom learning and student experience, and decide what to sustain, investigate, or change.

Research-backed practices lose value when implementation is inconsistent. Stanford’s work on high-impact tutoring, for example, emphasizes regular sessions, consistent and trained tutors, curriculum alignment, data-informed instruction, and implementation quality. Large-scale evidence also shows that effects can weaken when key elements are not carried out reliably. [3]

Schools face the same implementation problem beyond tutoring.

A team can understand a student’s need and still fail to produce change if no one owns the next step, the response is not carried forward, or the school never returns to examine what happened.

Workflows make responsibility, follow-through, and review explicit while preserving professional judgment about the individual student.

Research gives schools better starting points. It does not eliminate the need for professional judgment.

The evidence does not justify several shortcuts:

• Screening does not itself produce three or five months of additional learning. The benefit depends on what educators do with what they discover.
• A strong average effect does not mean every student will experience the same gain.
• Effect sizes from different practices cannot simply be added together.
• A change in student progress after an intervention does not, by itself, prove that the intervention caused the change.
• A score or category does not provide a complete explanation of a student.
• And evidence that an approach can work does not mean it will work equally well in every school.

The Education Endowment Foundation describes its own evidence summaries as “best bets,” not definitive predictions about what will happen in a particular setting. Context and professional judgment still matter. [7]

True Progress also develops frameworks that help educators apply these principles to recurring problems in schools.

These frameworks are informed by research and experience in schools. They should not be confused with independently validated interventions carrying their own research effect sizes.

True Progress does not claim that combining these practices produces a guaranteed effect size or that the complete Student Success System has been experimentally validated as a single intervention.

The system uses well-established research as a foundation and connects it with the professional knowledge already present in a school.

• Visibility helps educators understand students.
• Focused Curriculum identifies the learning that deserves attention.
• Instruction responds as learning unfolds.
• Meaningful Data helps the school interpret progress and examine whether its response is working.
• Workflows help decisions become dependable action and bring educators back to what happened next.

The common principle is simple: understand the student, make a considered response, and keep learning from what follows.
