IEP data collection: methods, sheets and schedules that hold up

Every IEP must say how progress toward each annual goal will be measured and when progress will be reported.^[1] Data collection is how you keep that promise. It is the weekly habit of scoring each goal the way the goal says, writing the number down, and graphing it.

Good data answers one question: is this student on track to meet this goal by the annual review? If your data sheets cannot answer that in a glance, the method, the sheet or the schedule is wrong. This guide covers all three, with a method table for every goal type, a filled-in example for each data sheet, and a weekly schedule for a 12-student caseload.

What to remember

• The goal picks the method. The verb and the criterion in the goal tell you whether to count, time, score trials or check steps.
• One goal, one data sheet, one unit. The baseline, every probe and the progress report all use the same unit.
• Define the behavior first. Two adults watching the same session should get the same score.
• Schedule it or it will not happen. A short probe on a fixed day beats a long session you never find time for.
• Graph it weekly. Numbers in a binder do not show a trend. A line on a graph does.

What IEP data collection is for

Data serves three jobs. It sets the baseline the goal is written from. It tracks progress during the year, so the team can change instruction when the line goes flat. And it backs the progress report that goes home to parents.

Repeated, brief measures taken the same way over time are the core of progress monitoring.^[2] That rules out a lot of what ends up in binders: worksheets with no score, anecdotal notes with no number, and a single test given in May. It also means the data you collect for a goal has to measure that goal, not something nearby. A spelling test is not data on a written expression goal.

For how the data feeds graphs, decision rules and reports, see the IEP progress monitoring guide. This page is about collecting the numbers in the first place.

The 11 measurement methods, matched to goal types

Each goal type has a method that fits it. The table below covers every measurement method in the library, with the data sheet that goes with it.

If you collect the same goal for several students at once, such as a small reading group, the group data sheet puts everyone on one page. When two methods both seem to fit, the guide on how to choose a data collection method walks from the goal verb to the method.

Step 1: Read the goal and name the unit

Start with the criterion in the goal. It almost always names the unit. "With 90% accuracy" means percent accuracy. "In 4 of 5 opportunities" means opportunity data. "Within 60 seconds" means latency. "For 15 minutes" means duration.

If the goal has no unit you can score, fix the goal before you build a data sheet. "Will improve organization" cannot be measured. "Will complete 8 of 10 steps of the end-of-day packing routine independently" can. Paste a draft into the goal checker to catch a missing criterion.

Watch the denominator. Percent accuracy counts items, while percent of opportunities counts chances to use a skill. They look alike on paper and mean different things, as the percent accuracy vs percent of opportunities comparison shows.

Step 2: Write the operational definition

An operational definition says exactly what counts. Write it at the top of the data sheet so a para or a substitute scores it the same way you do.

• Loose: "Is on task."
• Clear: "Eyes on the assigned material, pencil moving or hand raised, with no break longer than 10 seconds."
• Loose: "Uses coping strategies."
• Clear: "Within 2 minutes of a stated frustration, picks a strategy from the break card and uses it until the timer ends."

Check the definition once with a second adult. Score the same 10 minutes side by side and compare. If you disagree on more than one or two marks, tighten the wording before you collect more data.

Step 3: Pick the data sheet and set it up

Use one sheet per goal, set up before the first session. Fill in the student, the goal, the definition, the conditions and the prompt codes. Leave nothing for the person collecting to decide on the spot.

The free data sheets are built around each method. Each one has a place for the date, the score, the support given and a note. The filled-in examples later on this page show what a week of real entries looks like on each sheet. For printable trackers organized by goal type, see IEP goal tracking sheets.

Step 4: Decide how often to probe

A goal does not need data every day. It needs data often enough to show a trend before the next progress report. For most academic goals that means one short probe a week. For behavior goals that change from day to day, two or three short observations a week give a steadier picture.

Keep each probe the same length and under the same conditions. Five 1-minute fluency probes on Fridays are worth more than one 20-minute reading session scored by feel. The schedule section below shows how this fits a full caseload, and how often IEP progress should be monitored gives frequencies by goal type.

Step 5: Record the prompt level every time

A correct response with a gestural prompt is not the same as an independent one. If the goal says "independently," only unprompted responses count toward the criterion. Record the prompt anyway, because the drop from full physical to gestural to none is progress the team needs to see.

Use the same codes on every sheet, such as I for independent, G for gestural, V for verbal, M for model and P for physical. The prompt hierarchy examples show how to write prompt levels into goals and data sheets so the fading shows up in the numbers. The glossary entry on the prompt hierarchy has the short version.

Step 6: Graph and check weekly

Put each week's score on a line graph with the baseline and the goal line. Do it the day you collect, while the session is fresh. Then look at the last few points against the goal line. If they sit below it, change something in instruction before the next report is due. The guide to graphing IEP data with aimlines shows the setup, and the four-point rule tells you when to act.

You can graph by hand on the back of the data sheet or in a spreadsheet. If you track many students, IEP Atlas Pro runs sessions, graphs each goal and builds the progress report from the same data. Whichever you use, the graph is what makes the data useful.

Filled-in examples for each data sheet

These entries are illustrations of format, not targets. Names and numbers are fictional.

Accuracy data sheet

Goal: Given 20 mixed addition and subtraction facts within 20, Maria will answer with 90% accuracy on 3 consecutive weekly probes.

Opportunity data sheet

Goal: When she needs an item out of reach, Lena will request it using a 2-word phrase in 4 of 5 opportunities across 3 sessions.

One session might read: + + P − +. That is 3 independent of 5 opportunities, or 60%, with one prompted and one missed.

Frequency data sheet

Goal: During a 30-minute math block, Owen will call out without raising his hand no more than 3 times per block for 4 consecutive weeks.

Monday 9 tallies, Tuesday 7, Wednesday 11. Note the block length each day. If it varies, convert to rate.

Rate per minute on the frequency sheet

Owen's Thursday block ran 20 minutes with 6 call-outs, a rate of 0.3 per minute. His Monday block ran 30 minutes with 9 call-outs, also 0.3 per minute. The raw counts differ; the rate shows the behavior did not change.

Duration data sheet

Goal: During independent reading, Ezra will stay engaged for 12 consecutive minutes on 4 of 5 days.

Start the stopwatch when he opens the book, stop at the first break longer than 10 seconds. Monday 4 min 30 s, Tuesday 6 min, Wednesday 3 min 45 s.

Latency data sheet

Goal: After a whole-class direction to begin, Leo will start writing within 60 seconds on 4 of 5 observed work periods.

Seconds from direction to pencil on paper: 210, 140, 95, 180, 160. Median 160 seconds.

Rubric scoring data sheet

Goal: Given a prompt and a graphic organizer, Jordan will write a paragraph scoring 10 of 12 points on the class paragraph rubric in 3 of 4 samples.

Sample 1: topic 2, details 1, order 2, closing 0, total 5 of 12. Each row of the rubric is scored separately so you can see which part is growing.

Task analysis data sheet

Goal: Given a visual schedule, Ana will complete 9 of 10 steps of the arrival routine independently for 5 consecutive school days.

Monday: 6 steps I, 3 steps G, 1 step V. Total independent: 6 of 10. The sheet shows which steps still need a prompt, which tells you what to teach next.

Reading fluency data sheet

Goal: Given an unpracticed grade 3 passage, Sam will read 95 words correct per minute with 97% accuracy by the annual review.

Oct 6: 82 words attempted, 6 errors, 1 minute. That is 76 WCPM and 93% accuracy. Use the median of 3 passages if you give more than one.

Interval recording data sheet

Goal: During 20 minutes of small-group work, Aiden will be engaged in 80% of 1-minute intervals for 3 consecutive sessions.

Using momentary time sampling, he was engaged at the end of 11 of 20 intervals, or 55%. Leave a box blank if you could not see him, and divide by intervals scored.

Group data sheet

For a group of 4 students practicing the same comprehension skill, list each student down the left and each probe across the top. One page covers the group for the month.

A weekly data schedule for a 12-student caseload

Most case managers do not have time to probe every goal every day. A fixed weekly calendar spreads the work so each goal gets a data point and no day is overloaded. The example below covers a fictional resource caseload of 12 students with 31 goals. Each probe takes 1 to 5 minutes.

Behavior goals that vary day to day get extra points from staff who already see the student, such as a para recording frequency in the math block. Keep that sheet at the point of instruction, not in your office. The caseload tracker helps you keep the list of students, goals and report dates in one place.

Build in a catch-up day. Assemblies, absences and testing weeks will eat probes. Friday covers what was missed and gives time to graph. If a goal goes two weeks without a point, move it to the front of next week.

Who collects the data

The case manager owns the data, but does not have to collect all of it. Paras, related service providers and general education teachers can record data when the sheet is simple and the definition is clear.

• Paras record frequency, duration and task analysis well, since they are often with the student during routines. Train them on the definition with one shared session before they collect alone.
• General education teachers can mark opportunity data or a short frequency tally. Ask for one number, not a narrative.
• Related service providers collect their own goal data on their own schedule. Get a copy for the progress report window.

Whoever collects, the case manager checks the sheets weekly. Look for missing dates, blank prompt codes and scores that do not match the definition.

Keeping the data honest

Data is only useful if another adult would get the same number. A few habits keep it that way.

• Probe under the goal's conditions. If the goal says "unpracticed passage," never reuse a passage the student has read.
• Do not round up. Write 7 of 10, not "about 75%."
• Mark absences as absences. A blank cell with "absent" is honest. A zero is not.
• Check agreement once a quarter. Have a second adult score one session with you. Compare marks and fix the definition if you disagree.
• Date every entry. An undated score cannot go on a graph.

Common mistakes

• Weak: One worksheet per week with a grade at the top. Better: A fixed set of items scored with the accuracy sheet and graphed.
• Weak: "Had a good week" in the notes column. Better: "Started within 60 seconds on 3 of 5 work periods."
• Weak: Percent accuracy for an on-task goal. Better: Duration or interval recording, as frequency vs duration recording and the interval methods comparison explain.
• Weak: Counting a routine as done when the adult did half the steps. Better: A step-by-step sheet like the task analysis examples use, with each step marked by prompt level.
• Weak: Collecting data only in the two weeks before the report. Better: One point a week, every week, so the graph shows a trend.

Before the first session

The first data point of the year should be the baseline. If you already have it from the present levels, start the same sheet with those probes, so the graph begins at the starting point. For how to take that first set of probes, see how to collect baseline data.
