What is intervention dosage?
Definition
Intervention dosage is how much extra instruction a student actually receives: minutes per session, sessions per week, and weeks overall.
Planned dosage and delivered dosage are often very different. A schedule of 30 minutes, five days a week can shrink to 18 minutes, three days a week, once assemblies, absences and late starts are counted.
That gap matters when teams judge whether an intervention worked. A student who got half the planned time hasn't had a fair test of the intervention. Increasing the time may be the fix, not changing the program.
Tracking dosage is simple: record the date and the minutes every session. Over a month, the total tells you more than the schedule ever could. It's also one of the first things a team, an advocate or an evaluator asks to see.
In a lesson
A student's plan says 150 minutes a week. The log shows an average of 85 over six weeks, mostly because the group was cancelled on Fridays. The team fixes the schedule before changing the program.
Why does this matter for the record?
Log minutes for every session, including the ones that were cut short. Delivered minutes are the number that matters.
