IEP Goal Progress Calculator

Progress monitoring toward an IEP goal comes down to comparing how far a student has come against how far they need to go, and this calculator builds several views of that comparison from three scores and a timeline. It supports both kinds of IEP goal: a standard goal where Target Score is above Baseline Score (most academic and skill-acquisition goals), and a reduction goal where Target Score is below Baseline Score (common for behavior-frequency or error-rate goals, where fewer incidents is the win) -- Goal Progress, Remaining Gap, and Weekly Improvement Rate are all computed relative to whichever direction the goal actually points, so a reduction goal where the score is falling toward its target reads as positive progress rather than 0%. Goal Progress is Progress Made (Current Score minus Baseline Score) divided by the Total Gap (Target Score minus Baseline Score), so it's purely a measure of score movement -- it does not reference Weeks Elapsed or Total IEP Weeks at all. It is capped at -100% to 200%: a Target Score set only barely above (or below) Baseline Score produces a very small Total Gap denominator, which can swing the raw ratio to an extreme percentage for even modest real progress, so beyond the cap the number stops being informative and Progress Made / Remaining Gap (both uncapped, in the goal's own score units) tell the real story of how far the student has moved.

Status compares that percentage against Time Elapsed (Weeks Elapsed divided by Total IEP Weeks, capped at 100%) separately: "On Track" means the percentage of the goal completed is at least as large as the percentage of the IEP period that has passed, which is a proportional pacing check, not a guarantee the student will actually hit the target score by the deadline. Weekly Improvement Rate is the pace achieved so far, signed so a positive number always means "moving toward the goal" regardless of whether the goal is to raise or lower the score, and Required Rate to Meet Goal divides the Remaining Gap by the weeks left in the period on that same convention -- comparing the two tells you whether the student's current trajectory needs to accelerate to close the gap in time. Projected Final Score extends the student's actual (unsigned) rate of score change forward across the remaining weeks, which assumes progress continues at a constant linear pace -- real intervention progress is rarely perfectly linear, so treat the projection as a trend line, not a prediction.
