Why do students continue to need additional support, even after you’ve invested in intervention?
You’ve invested in specialist staff, additional learning time, and instructional resources. Yet each assessment cycle identifies more students who need help with foundational literacy and numeracy skills.
Growing support needs are a reason to look closely at students’ classroom experiences alongside the interventions they receive. Are similar difficulties appearing across classes? Do teachers have the resources, planning time, and professional learning they need? How well does additional support connect with everyday teaching?
Strong core instruction is an important part of that picture. Reviewing it can help school and board leaders identify where improvements may benefit students across classrooms, while maintaining targeted support for those who need it.
Here are five signs worth investigating—and practical steps to guide your response.
What do we mean by core instruction?
Core instruction is the teaching students receive as part of their regular classroom program. It includes how teachers introduce concepts, model skills, guide practice, check understanding, and respond to learning needs.
Some Canadian education systems describe this as Tier 1 within a tiered approach to support. Terminology and implementation vary across provinces, territories, boards, and districts, so the focus here is on the classroom experience rather than a particular framework.
Three connected elements are useful to consider:
- Core classroom instruction: Teaching designed to make curriculum learning accessible to all students.
- Targeted support: Additional instruction focused on particular skills or learning needs.
- Intensive intervention: More individualized support, informed by assessment and ongoing progress monitoring.
These elements should work together. Strengthening classroom instruction does not replace intervention, accommodations, or specialized services.
Sign #1: Lessons cover curriculum expectations, but students struggle to retain and apply their learning
A curriculum plan can cover the required content without giving students enough time or support to understand it.
Watch for lessons that introduce several unfamiliar ideas at once, move quickly from demonstration to independent work, or provide limited opportunities to revisit earlier learning. Students may complete an activity successfully but struggle to explain or apply the same concept later.
These patterns warrant a closer look at lesson sequencing and practice—not an assumption about students’ abilities.
What school and board leaders can do:
Review a specific learning sequence with teachers. Consider:
- How is new learning connected to what students already know?
- Are explanations and demonstrations clear?
- Is unfamiliar content introduced in manageable steps?
- Do students receive guided practice and timely feedback?
- Are earlier skills revisited over time?
When reviewing resources, ask suppliers to demonstrate these features in actual lessons. Include teachers in the review so you can assess both instructional quality and classroom usability.
Look beyond curriculum coverage. Examine how materials help teachers build understanding, provide practice, and respond when students need more support.
Sign #2: Literacy has a clear improvement plan, but numeracy receives less coordinated attention
Your school or board may have established literacy priorities, dedicated professional learning, and a clear process for reviewing reading resources. Does numeracy receive the same level of planning?
A less coordinated approach can leave teachers without a shared understanding of which foundational math skills need attention or how learning should develop across grades.
Early numeracy planning should consider students’ understanding of quantity, number relationships, operations, and mathematical reasoning. It should also examine how teachers connect concrete materials, visual representations, mathematical language, and symbols.
What school and board leaders can do:
Review literacy and numeracy priorities together. Identify where teachers have strong support and where additional resources, collaboration, or professional learning would help.
When evaluating math materials, ask:
- How do they align with the applicable provincial or territorial curriculum?
- How do they develop conceptual understanding, procedural fluency, and problem-solving?
- What opportunities do students have to explain their thinking?
- How do they help teachers identify and address misconceptions?
The aim is to give each domain a clear instructional plan, with resources matched to the learning priorities.
Give foundational numeracy a defined place in your improvement plan, with clear priorities and practical support for teachers.
Sign #3: Assessment identifies who needs help, but rarely changes classroom instruction
Assessment can help identify students who need additional support. It should also prompt questions about what is happening across classrooms.
If many students struggle with the same skill, what might that tell you about the learning sequence, opportunities for practice, or explanations they have received?
A score alone cannot answer those questions. Teachers need to examine assessment information alongside student work, classroom observations, and conversations with learners.
What school and board leaders can do:
Make time for teachers to review evidence together and identify an instructional response.
Ask:
- Which difficulties are shared across a class or grade?
- Which students need further assessment to understand their needs?
- What should be retaught, modelled differently, or practised more?
- How will teachers check whether the response helped?
When reviewing digital resources, examine sample reports. Can teachers see which skills students are finding difficult? Is the information specific enough to guide a teaching decision? Does the resource’s curriculum alignment reflect your jurisdiction?
Connect assessment to a clear next step in teaching—and a plan to check students’ progress.
Sign #4: Additional support is expanding, but the same learning difficulties keep appearing
Repeated patterns of difficulty deserve attention. If successive groups of students need help with the same foundational skills, review how those skills are taught and supported in the regular classroom program.
This does not establish that classroom instruction is the sole cause. Attendance, language-learning needs, disabilities, access to learning opportunities, and other factors may also affect progress.
The purpose of a review is to understand the pattern and improve provision, while continuing the support students need.
What school and board leaders can do:
Examine classroom instruction and intervention together:
- Are students receiving consistent opportunities to learn the relevant skills?
- Does additional support connect with classroom teaching?
- Can classroom teachers and specialist staff plan and review progress together?
- Are resources and staffing matched to identified needs?
- What implementation barriers are teachers experiencing?
Review spending alongside these questions. Include materials, staffing, professional learning, and planning time, rather than assuming a new program alone will resolve the issue.
Judge improvement through students’ learning and access to appropriate support. A shorter intervention list, by itself, is not evidence of success.
Use recurring learning needs to guide a coordinated review of classroom teaching, additional support, and resource allocation.
Sign #5: Teachers have flexibility, but limited shared guidance or resources
Professional judgment helps teachers respond to their students. It is most useful when supported by clear learning priorities, suitable materials, and opportunities to collaborate.
Where those supports are missing, teachers may spend substantial time finding resources or developing lesson sequences independently. Students may also encounter gaps or unnecessary repetition as they move between classrooms and grades.
A shared approach can provide continuity while leaving room for responsive teaching.
What school and board leaders can do:
Work with teachers to agree on practical expectations for high-quality instruction. These might include:
- Clear learning goals aligned with the relevant curriculum.
- Purposeful explanations and modelling.
- Guided and independent practice.
- Regular checks for understanding.
- Accessible materials and appropriate accommodations.
- Opportunities to revisit and apply learning.
Support those expectations with collaborative planning, professional learning, and usable resources.
When considering a program, review the research behind it, the learners and settings studied, and its relevance to your intended use. Consider that evidence alongside curriculum fit, accessibility, and implementation requirements.
Build a shared instructional foundation with teachers, and give them the time and resources to put it into practice.
Turn the review into a focused improvement plan
You do not need to address every aspect of core instruction at once.
Choose one clearly defined literacy or numeracy priority. Establish what students currently know, identify the changes teachers will make, and agree on the support required.
Before implementation, decide how you will review:
- Progress in the specific skills being taught.
- Teachers’ experience using the approach or resource.
- Consistency of implementation.
- Planning and administration time.
- Students’ continuing support needs.
- Total implementation costs.
This gives leaders a practical basis for deciding what to continue, adapt, or reconsider.
Strong core instruction deserves sustained attention as part of a coordinated approach to student learning—alongside targeted intervention, accessible teaching, and specialized support.
