Progress monitoring
What makes progress monitoring valid?

Quick answer
Valid progress monitoring has four parts: a baseline, a measurement method that matches the goal, a schedule the team actually follows, and dated evidence behind each data point. IDEA requires every IEP to describe how progress will be measured and when reports go to families.
What the law asks for
Under 34 CFR 300.320(a)(3), each IEP must describe how the child's progress toward annual goals will be measured and when periodic reports on that progress will be provided. The Supreme Court's Endrew F. decision added that an IEP must be reasonably calculated to enable progress appropriate in light of the child's circumstances. Both point to the same thing: data you can stand behind.
The four parts
Choosing the right method
The method has to match the words in the goal. A reading fluency goal written in words correct per minute needs timed passages. A behavior goal written as a frequency needs a count over a defined period. A goal written as percent accuracy needs a known number of opportunities, so the percent means something.
Mismatches are common because goals and data collection are often designed by different people at different times. A quick fix is to read each goal aloud and ask, "What would I have to count or score to know this is true?" If the answer is not already part of the plan, the method needs to change or the goal needs to be rewritten at the next meeting.
Common gaps
- A goal written in percent accuracy, measured by teacher observation with no count.
- Three data points collected the week before reports are due.
- Progress notes that describe effort rather than performance.
- No way to tell who collected the data or when.
Making the schedule realistic
A schedule is only valid if it is followed. Weekly probes sound good in an ARD or IEP meeting, but if a case manager has 30 students and each has three goals, that is 90 probes a week before anything else happens. Teams are better served by a schedule they can keep, such as every other week for most goals and weekly for goals where the student is not moving.
It also helps to spread collection across the people who already work with the student. A general education teacher, a paraprofessional or a related service provider can often capture a data point during the work they are already doing, as long as the method is clear and the entry takes seconds.
How leaders can check
Pick five IEPs on a campus. For each goal, ask to see the baseline, the last three data points with dates, and the method. If that takes more than a few minutes to find, the system is relying on memory. That is fixable, and it is much easier to fix in October than in May.
Using the data between reports
The value of progress monitoring is not the report that goes home every six or nine weeks. It is the conversation the data makes possible in between. When a student has four flat data points in a row, the team does not need to wait for the annual review to adjust instruction. IDEA already expects teams to revise the IEP when there is a lack of expected progress. Good monitoring simply makes that visible early enough to act.
