Progress tracking for autism care
Two therapists can score the same child differently, and the same child scores differently at home than in clinic. So a rising line might be real progress, or just a change in who measured and where. Throughline estimates those effects and removes them, so clinicians see the child's underlying progress instead of measurement noise.
Where standard tracking breaks down
It means removing the part of a score that comes from who rated the child and where, so what is left reflects the child's actual ability. A raw score blends all three. Throughline pulls them apart.
Standard progress tracking
Throughline
Raters disagree more than people expect. Inter-rater agreement on VB-MAPP runs around an ICC of 0.63, so close to a third of a score is the rater, not the child. The correction is established psychometrics. Putting it in a clinician's hands, live, is what is new.
Artifact progress
Raw scores climb while the deconfounded line stays flat. Gains that are really a more lenient rater or an easier setting.
Real regression
A decline that survives correction. Real loss of skill, not one rough afternoon at home.
On track
Gains that hold up after deconfounding. Progress a clinician can act on with confidence.
