| Strategy | What it does | Planning use |
|---|---|---|
| Tiered assignments | Offer learners multiple versions of a task so they work toward the same objectives at different support levels | Use when readiness varies but the learning target is shared. Check that every version leads to the same objective. |
| Choice boards | Present a variety of activities or tasks related to a particular learning objective in a visual organizer | Use to give students a say in how they practise or show learning. Keep every option tied to the objective. |
| Flexible grouping | Groups are not stationary; students move between them as assessments show mastery | Pair each grouping plan with a regular check that triggers movement. Look for groups that have changed since the last visit. |
Tiered assignments and choice boards are described in a publisher’s guide to differentiation strategies, and the non-stationary grouping condition in guidance on differentiating for students with learning disabilities.
Differentiated instruction strategies modify lessons to fit each child’s needs: teachers adjust content, process and product while keeping one learning target. They work only when ongoing checks of student needs drive each adjustment.
Observing this work is part of instructional leadership, and the hub that explains what does a school principal do places that observation in the wider role.
What differentiated instruction means in practice
Differentiated instruction is where teachers modify their lessons to accommodate each child’s unique needs, as a peer-reviewed review in PubMed Central puts it. A publisher’s guide frames it as an inclusive approach that acknowledges and accommodates the diverse needs, interests and readiness of students. The shared point is that the standard stays in place while the route to it changes.
That framing matters for how a school judges the work. Differentiation is not a separate programme or a set of worksheets. It is a set of teaching decisions about what students meet, how they work on it and how they show what they have learned. Those three levers, content, process and product, organise the rest of this guide.
Implications for teachers and school leaders
The first consequence of differentiating is that planning moves upstream. The PubMed Central review notes that differentiation necessitates numerous intentional decisions about teaching, so a teacher who differentiates well is making choices before the lesson, not only improvising during it. The choices below tend to decide whether the effort holds up.
- Plan decisions, not extra paperwork. Choose a small number of strategies, such as tiered tasks or choice boards, and apply them consistently rather than building separate resources for every student.
- Expect groups to move. Flexible grouping only works when groups are not stationary and students can move about as they master skills.
- Hold one target constant. Tiered assignments and choice boards both work toward the same objective, so a difference in support or format should never become a difference in expectation.
- Resource the approach. The review concludes that it takes system-wide research, teacher training and resources, which makes differentiation a school-level commitment as well as a classroom one.
What to look for in observations
Observers can check differentiation without a long rubric. The following signs are consistent with the strategies described in the evidence.
- Groups that have changed. Ask how students were placed and when they last moved. Teachers must continually assess throughout the school year and move students within the groups.
- Shared objective, varied support. Compare the task versions on a table or screen. They should lead toward the same objective, not different ones.
- Stations with distinct methods. Each station should use a unique method of teaching a skill or concept related to the lesson. Stations that repeat the same worksheet are not differentiation.
- Structure inside the task. Learning broken into chunks, with a concrete structure for each, is how Edutopia describes support for every student.
- A check feeding a decision. A low-stakes check should be followed by a visible change in grouping, task or support, not simply collected.
Routines for moving between groups and stations are developed in Classroom Management Strategies: 7 Practical Approaches Every Teacher Needs In 2026 – Principalspartnership. Teachers who share a room can compare ways of splitting groups in Co-Teaching Strategies That Work: Practical Models, Planning Tips, and Classroom Moves for 2026 – Principalspartnership.
How far the evidence reaches
The PubMed Central review reports that successful implementation improves academic performance, motivation and engagement. The case studies behind that finding come mainly from foreign language classrooms. Leaders should therefore treat it as encouraging evidence for supporting the practice, and should not promise a particular result in every subject or grade.
Content, process and product
A classroom guide from a learning-games company separates the three levers clearly. Content covers the media and methods through which students meet the material. Processes are the exercises and practices students perform to understand that content. Products are the materials, such as tests and projects, students complete to demonstrate understanding. Changing one lever at a time keeps the planning manageable and makes it easier to see what helped.
Content
Content differentiation changes how students access the material, not which standard they are working toward. Task cards offered at various levels are one way to do this. Tiered assignments are another, and a science example from the publisher’s guide shows the range of support. Students with the least support receive pre-cut images and labels of each stage of the butterfly life cycle to paste on a diagram. Students who need less help can build the diagram themselves from the same objective.
Process and scaffolding
Process differentiation changes the activity and the amount of guidance. The PubMed Central review describes it as varying activities and tailoring the level of guidance during inquiry and design tasks. Scaffolding is the practical form this takes, and the examples differ by subject.
- Math. A student who struggles might use manipulatives or a calculator to solve problems. Solve a problem together before asking students to try one on their own.
- Writing. Start with brainstorming as a group, then guide students through outlining, drafting and revising, so a long task becomes manageable steps.
- Stations. Set up stations that each teach the skill by a different method, and rotate students according to readiness.
Scaffolds are most useful when they are tied to a current check of what a student can do. Without that link they tend to harden into permanent support, which is why the grouping and assessment habits above matter.
Product
Product differentiation lets students show the same learning in different forms. A choice board is the simplest vehicle, because it lays out related tasks under one learning objective. The review finds that students respond especially well when given choices that align with their interests and strengths, which supports motivation and ownership. The condition is that every option is judged against the same success criteria, so choice does not lower the bar.
Assessment that guides differentiation
Assessment decides which of these levers to move, and for whom. The PubMed Central review says teachers should consistently monitor and assess their students’ needs and make deliberate decisions based on those evaluations. A publisher’s guide describes the same loop as ongoing assessment, progress monitoring and observation to understand the needs, interests and readiness of students. In short, formative assessment is what keeps differentiation responsive and not fixed at the start of a unit.
Frequent, low-stakes checks also fit the evidence on literacy: Edutopia reports that frequent low-stakes formative assessments help students achieve literacy goals. Low stakes matter because students are more likely to show what they do not yet understand when a check does not count against them.
A formative check list
Use this list to see whether a classroom has the checks that make differentiation work.
- Start-of-year preference survey. A paper survey at the beginning of the year quickly captures how students prefer to learn. Track the results to identify themes and students with uncommon preferences.
- Monitoring before and during planning. Teachers monitor needs ahead of the lesson and adjust it, rather than waiting for a unit test.
- Frequent low-stakes checks. Short checks during lessons give a current picture of who needs more support and who is ready to move on.
- Observation and progress monitoring. These sit alongside formal checks and capture needs, interests and readiness that a quiz can miss.
- A decision rule. Each check should lead to a stated action: regroup, reteach, change the support or extend the task.
Frequently asked questions
Can a product change without lowering the learning target?
Yes. A student with a writing disability might give an oral presentation instead of a written report, and the objective stays the same. What changes is the format, so the success criteria should name the learning and not the medium.
What does regrouping look like after a formative check?
Analysis of formative assessment data may show that some students in a small group have mastered long vowel sounds. Those students move to a group working on the next skill, while the rest continue with the current one.
Is differentiation too time-consuming to start?
Not necessarily. Edutopia notes that differentiating instruction can be less difficult and time-consuming than many educators anticipate. A sensible start is to build the habit of frequent low-stakes checks and act on them, then add tiered tasks or choice boards.
