Grouping students for reading intervention
By the IEP Atlas editorial teamLast updated
Short answer
Group students for reading intervention by the specific skill that is breaking down, not by overall score or grade. Sort screening and diagnostic data into skill bands, form groups of 3 to 5 who share the same starting point, make groups smaller for the students furthest behind, track every student on one group data sheet, and regroup every 6 to 8 weeks.
A reading group works when everyone in it needs the same lesson. Put a student who cannot blend CVC words next to one who misreads vowel teams, and the teacher has two choices: teach one and lose the other, or teach both badly. Grouping by shared skill gap fixes that, and it matters more than the program you pick.
This page walks through grouping one grade's worth of students, then shows how to use the group data sheet to keep groups honest. For the full intervention cycle, see the reading intervention pillar.
What you need before you start
- Screening scores for every student, with subtest scores and accuracy.
- A quick diagnostic for each flagged student, such as a phonics survey. The diagnostic reading assessment guide shows how to run one in about 40 minutes.
- The intervention block schedule and the staff available in each slot. The reading intervention schedule page covers building the block.
- The IEP goals of any students with IEPs, so groups can line up with them.
- One copy of the group data sheet per group.
Step-by-step grouping
Step 1: List every flagged student with their skill gap
Make one row per student with the screening score, accuracy and the first skill on the diagnostic that is not solid. Example: "Maya, grade 2, 31 WCPM, 82% accuracy, gap starts at short vowels."
Step 2: Sort students into skill bands
Use the order in which reading skills develop. A simple set of bands works for most K to 5 schools:
| Band | Skill gap | Typical evidence |
|---|---|---|
| A | Letter sounds and phonemic awareness | Low letter sounds, low segmenting |
| B | Short-vowel decoding and blending | Letter sounds solid; CVC words under 80% |
| C | Blends, digraphs, silent e | CVC solid; errors on blends and silent e |
| D | Vowel teams and r-controlled vowels | Single-syllable patterns solid until vowel teams |
| E | Multisyllable words | One-syllable words solid; long words break down |
| F | Fluency only | Accuracy 95% or higher, slow rate |
| G | Comprehension and vocabulary | Accurate and fluent; weak retell and questions |
Example: Maya goes in band B.
Step 3: Form groups of 3 to 5 within a band
Inside each band, form groups of 3 to 5 students. If a band has 9 students, make two groups of 4 or 5, not one of 9. Students from different grades can share a group if they share a band and the schedule allows. Example: a grade 2 and a grade 3 student who both start at vowel teams belong together more than two grade 2 students with different gaps.
Step 4: Make groups smaller for the students furthest behind
The more intensive the need, the smaller the group. Students in bands A and B who are far below benchmark, or who did not respond to an earlier group, often need groups of 2 or 3 with more minutes. The What Works Clearinghouse guide on primary-grade reading support recommends small-group instruction on a few foundational skills for students below benchmark, typically three to five times a week for 20 to 40 minutes.[1] Example: band A has 6 students; the 2 lowest form a pair with a reading specialist, the other 4 form a group with an interventionist.
Step 5: Match staff to groups
Put the most experienced teacher with the students who need the most skilled instruction. Trained paraprofessionals can run a scripted fluency or review group under supervision. Example: the reading specialist takes the band A pair and the band B group; a trained para runs the band F fluency group.
Step 6: Set a group goal and an individual baseline
Every group gets one target skill and one probe that measures it. Every student in the group gets a baseline on that probe. Example: band D group target is vowel-team words; probe is a 20-word vowel-team list every 2 weeks plus a weekly passage.
Step 7: Regroup every 6 to 8 weeks
Students move at different speeds. At each data review, move students who have mastered the group skill up a band, and look hard at students who are flat. Groups are temporary. Example: at week 6, two students in the band C group have mastered silent e and move to band D; a new student who screened in midyear joins band C.
Using the group data sheet
The group data sheet puts every student in a group on one page, so the teacher can record a probe for each in a few minutes and see at a glance who is moving. Use it like this:
- Header. Write the group name, band, target skill, probe and schedule at the top.
- Rows. One row per student, with baseline and goal in the first columns.
- Columns. One column per probe date. Probe one or two students each session so everyone is probed every 1 to 2 weeks without losing teaching time.
- Mark the decision. Circle any student whose last 4 points are below their goal line.
- Bring it to every data meeting. The sheet is the regrouping tool.
Here is a filled-in example for a band D group (all numbers illustrative). Scores are vowel-team words read correctly out of 20.
| Student | Baseline | Goal (week 12) | Wk 2 | Wk 4 | Wk 6 | Decision at week 6 |
|---|---|---|---|---|---|---|
| Andre (grade 4) | 6 | 17 | 9 | 13 | 16 | On track; check for move to band E at week 8 |
| Lily (grade 3) | 8 | 18 | 9 | 10 | 10 | Flat; check attendance and errors; consider smaller group |
| Omar (grade 3) | 5 | 16 | 8 | 11 | 13 | On track |
| Zoe (grade 4) | 7 | 17 | 12 | 17 | 19 | Mastered; move to band E |
Lily's data prompts a closer look. Her teacher finds she is confusing "ea" and "ee" in nearly every word, which the group lesson moves past too quickly. She gets 5 extra minutes of targeted practice and a recheck in 2 weeks.
Worked example: grouping one grade
A fictional school has 68 third graders. Fall screening flags 17 below benchmark. Diagnostics take the interventionist about 4 days.
| Band | Students | Groups formed | Staff | Minutes per week |
|---|---|---|---|---|
| B: short vowels | 2 | 1 pair | Reading specialist | 5 x 40 = 200 |
| C: blends, silent e | 4 | 1 group of 4 | Reading specialist | 4 x 30 = 120 |
| D: vowel teams | 5 | 1 group of 5 | Interventionist | 4 x 30 = 120 |
| E: multisyllable | 3 | 1 group of 3 | Interventionist | 4 x 30 = 120 |
| F: fluency only | 3 | 1 group of 3 | Trained para | 3 x 20 = 60 |
That is 5 groups across two 30- to 40-minute slots. The pair in band B includes a student with an IEP whose decoding goal uses the same CVC probe, so one graph serves both purposes. The student's specially designed instruction is listed in the IEP, and the group is where part of it happens.
Common mistakes
- Weak: Grouping by overall screening band ("all the red students"). Better: Group by the first skill that is not solid.
- Weak: One group of 8 because the schedule is tight. Better: Two groups of 4 in staggered slots, or a para-led review group for the higher band.
- Weak: Keeping groups fixed from September to June. Better: Regroup every 6 to 8 weeks from the group data sheet.
- Weak: Putting the least trained adult with the neediest students. Better: Most skilled teacher, smallest group, most minutes for the students furthest behind.
- Weak: Probing only at benchmark windows. Better: Probe each student every 1 to 2 weeks on the group's target skill.
- Weak: Separate groups for students with IEPs regardless of skill. Better: Group by skill, and make sure the IEP's services and minutes are still delivered.
Tools and next steps
- Plan each lesson with the small-group reading lesson plan.
- Write each student's plan with the reading intervention plan template.
- Compare layers in tier 2 vs tier 3 intervention.
- Use the reading IEP goals library for students whose group goal should match an IEP goal, and check draft goals in the goal checker.
The group data sheet also covers the documentation a team will need if a student's lack of progress leads to an evaluation for a learning disability, which looks at repeated assessments of achievement during instruction.[2]
Frequently asked questions
What is the best group size for reading intervention?
Most schools use 3 to 5 students for targeted support and 1 to 3 for intensive support. The students furthest behind should be in the smallest groups with the most minutes and the most skilled teacher.
Can students from different grades be in the same reading group?
Yes, if they share the same skill gap and the schedule allows. A grade 3 and a grade 4 student who both start at vowel teams need the same lesson, even though their grade-level classes differ.
How often should reading intervention groups change?
Review the data every 6 to 8 weeks and regroup then. Move students who have mastered the group skill up a band, and look closely at any student whose recent probes stay below the goal line.
