How do I choose between different reading and math intervention publishers for a child who needs foundational skills support?

Choosing between intervention publishers is mostly about fit, not brand. The best program is the one that matches the child’s needs, the way your school can deliver instruction, and the evidence you can verify.

1) Start with the child’s specific skill gaps

Look for the lowest-level skills that are weak, not just grade level.

• Reading: phonological awareness, phonics, decoding, fluency, vocabulary, comprehension
• Math: number sense, counting, fact fluency, place value, computation, word problems

A child who struggles with decoding needs a very different program than one who can read words but doesn’t understand what they read.

2) Check whether the program is explicit and systematic

For foundational skills, strong interventions usually:

• teach skills in a clear order
• use direct instruction
• include guided practice and review
• build in cumulative rehearsal
• give lots of opportunities to respond

If a publisher’s materials are vague or “discover-based,” they may be less effective for core skill deficits.

3) Look for evidence, not just marketing

Ask:

• Has the program been studied with children similar to yours?
• Are there independent studies, not only publisher-funded ones?
• Does it have evidence for the exact area of need, like early decoding or number sense?

Useful terms:

• Tier 2 / Tier 3
• evidence-based
• RCT or quasi-experimental studies
• what outcomes improved and for which students

4) Match the intensity to the need

Consider:

• group size: 1:1, small group, whole group
• session length: 20, 30, 45 minutes
• frequency: 3–5 times per week
• duration: weeks or months

A strong program can still fail if it’s not delivered often enough.

5) Decide whether you need a scripted or flexible program

• Scripted programs help with fidelity, especially for staff without specialized training.
• Flexible programs may be easier to adapt but require stronger instructional knowledge.

If staff turnover or training is a concern, script and structure can be a big advantage.

6) Check progress monitoring and data use

Good intervention publishers provide:

• placement assessments
• progress monitoring tools
• decision rules for moving students up or changing support

You want a program that tells you whether it’s working within weeks, not months.

7) Evaluate accessibility and usability

Ask:

• Is it easy for the teacher/tutor to use correctly?
• Does it include decodable texts, manipulatives, visuals, or audio supports?
• Is it appropriate for attention, language, or executive-function needs?
• Does it work with multilingual learners if relevant?

Even a strong program may be hard to implement if materials are confusing or time-consuming.

8) Compare cost and implementation burden

Consider:

• licensing cost
• materials required
• training time
• ongoing coaching
• digital platform needs
• scheduling demands

Sometimes a slightly less expensive program costs more in practice because it takes too much staff time or training.

9) Ask for a sample lesson and a full scope and sequence

Compare publishers by looking at:

• how they introduce new content
• how they review old skills
• whether lessons are logically sequenced
• whether practice is enough
• whether the reading level of materials matches the learner’s decoding ability

10) Pilot before fully committing, if possible

Try 4–8 weeks and monitor:

• student engagement
• fidelity of delivery
• rate of progress
• teacher feedback

If the child isn’t improving, the issue may be the match, the dosage, or the implementation—not necessarily the child.

A simple decision rule

Choose the publisher/program that best answers “yes” to these:

1. Does it target the child’s exact foundational gaps?
2. Is it explicit and systematic?
3. Is there credible evidence for students like this?
4. Can we deliver it with enough intensity and fidelity?
5. Can we monitor progress and adjust quickly?
6. Will staff actually be able to use it well?

If you want, I can also give you:

• a comparison checklist you can use across publishers, or
• a reading vs. math intervention selection guide based on the child’s specific difficulties.
