How to collect IEP data while teaching
By the IEP Atlas editorial teamLast updated
Short answer
To collect IEP data while teaching, plan which 2 or 3 goals you will measure in each lesson, prepare the data sheet with names and goals before class, and score a short probe instead of every response. Keep the sheet in your hand, use tallies or a counter, and spend 2 minutes after the lesson filling gaps. Rotate goals across the week.
Most teachers do not fail at data collection because they do not care. They fail because they try to score every response for every goal for every student, and teaching wins. The fix is to collect less, on purpose, and plan where it happens.
A weekly data point on each goal is enough for most academic goals. Repeated short measures over time give the trend the IEP team needs.[1] You do not need 30 data points a week to see a trend. You need 1 to 3 clean ones. For the whole system, see the pillar on IEP data collection.
What you need before you start
- Each student's goals, with the measure each one uses
- Your weekly lesson plan
- A clipboard, a pen, and a tally counter or a few sticky notes
- One data sheet per group, pre-filled with names and goals
Step-by-step, with the time each step takes
| Step | When | Time |
|---|---|---|
| 1. Map goals to lessons | Weekly planning | 10 minutes a week |
| 2. Prep the sheet | Before class | 2 minutes |
| 3. Pick the probe moment | In the lesson plan | 1 minute |
| 4. Score while teaching | During the lesson | Seconds per mark |
| 5. Do a 2-minute catch-up | Right after the lesson | 2 minutes |
| 6. Graph weekly | End of week | 5 to 10 minutes |
That is about 30 minutes a week for a small group, most of it planning.
Step 1: Map goals to lessons
Look at the week and decide which goals you will measure in which lesson. Measure each goal at least once a week, and no more than 2 or 3 goals in any one lesson.
Example: Monday reading group measures fluency for 2 students. Tuesday measures decoding for the other 2. Wednesday and Thursday are teaching days with no planned data. Friday measures comprehension for all 4.
Step 2: Prep the sheet
Fill in names, goals and the date before the lesson. A blank sheet in the middle of a lesson is a sheet you will not use. A group data sheet puts every student in one grid. The guide to group data collection shows how to lay it out.
Step 3: Pick the probe moment
Choose the 2 to 5 minutes of the lesson where the goal skill happens. For a decoding goal, it is the word list warm-up. For a question-asking goal, it is the partner talk. Write it in your plan: "Warm-up, score Ana's 10 words."
Score the first try, or a set of 5 to 10 trials, not every response all period. A cold probe at the start of the lesson, before teaching, shows what the student retained.
Step 4: Score while teaching
Keep the sheet in your hand or on the table, not on your desk across the room. Use the fastest mark that works:
- Tally marks for frequency, such as questions asked.
- + and minus for correct and incorrect trials.
- Prompt codes (I, G, V, M, P) for task steps. See prompt hierarchy examples.
- A counter or bead bracelet when your hands are busy. Write the count down when you stop.
Step 5: Do a 2-minute catch-up
Right after the lesson, before the next group sits down, fill in anything you held in your head. Write a note if something unusual happened, like a fire drill or a new seat. After 10 minutes, you will not remember.
Step 6: Graph weekly
Move the week's scores to a graph on Friday. A graph shows a flat line by week 4. A pile of sheets shows it at report time. The IRIS Center's classroom assessment module walks through graphing and reading a trend.[2] See how to graph IEP data with an aimline.
Worked example from start to finish
Fictional class: a resource room math group of 4 grade 3 students, 40 minutes daily.
Goals to measure:
- Leo: addition facts to 20, rate per minute. Baseline 12 correct per minute.
- Ava: two-digit subtraction with regrouping, percent accuracy. Baseline 4 of 10.
- Sam: asking for help, frequency. Baseline 0 to 1 per lesson.
- Nia: telling time to 5 minutes, percent accuracy. Baseline 3 of 10.
Plan for the week:
| Day | Probe | Who | Time in lesson |
|---|---|---|---|
| Monday | 1-minute fact sheet | Leo | Warm-up, 1 minute |
| Tuesday | 10 subtraction problems | Ava | Independent practice, 6 minutes |
| Every day | Tally of help requests | Sam | Whole lesson, a mark each time |
| Wednesday | 10 clock faces | Nia | Warm-up, 4 minutes |
| Friday | Repeat Leo's and Ava's probes | Leo, Ava | Warm-up and practice |
What the teacher's sheet looked like on Friday: Leo 15 correct per minute. Ava 6 of 10. Sam: 2, 1, 3, 2, 3 help requests across the 5 days. Nia (from Wednesday) 5 of 10.
Time spent: 10 minutes planning on Sunday, 2 minutes of prep each day, about 12 minutes of scoring across the week, 2-minute catch-ups, and 8 minutes graphing on Friday. Roughly 40 minutes for 4 students and 4 goals, with no lesson interrupted.
What the data showed after 6 weeks: Leo and Sam were on track. Ava's line was flat at 5 to 6 of 10, so the teacher added base-ten blocks before the written step and dated the change on the graph.
Common mistakes
| Weak | Better |
|---|---|
| Trying to score every response for every goal | Pick 2 or 3 goals per lesson and score a 5 to 10 trial probe |
| A blank sheet you fill in during the lesson | Names, goals and date filled in before class |
| Data sheet on the desk across the room | Sheet on a clipboard in your hand |
| "I'll write it up at lunch." | A 2-minute catch-up right after the lesson |
| Scoring a different task each week | Same probe type, same length, every time |
| Data only when someone remembers | A planned probe moment written in the lesson plan |
| Collecting data and never graphing it | Graph every Friday and change instruction when the line is flat |

Frequently asked questions
How often do I need to collect IEP data?
At least once a week for most academic goals, and more often for behavior goals or goals where the student is close to mastery. Check the IEP, which states how progress will be measured.
Can I collect data on a sample of trials instead of every trial?
Yes. A short probe of 5 to 10 trials, or the first trial of a session, gives a cleaner picture than trying to score everything. Use the same probe size every time so scores compare.
What if I miss a planned data day?
Collect it at the next lesson and note the date. One missed probe does not ruin a graph. A pattern of missed weeks does, so put the probe moments in your lesson plan.
