What It Does Not Do
It does not create goals, recommend interventions, explain why progress changed, or generate clinical conclusions beyond the aggregate score and supported descriptive positioning.
Does this tool create GAS goals?
No. It summarizes existing individualized goal-attainment ratings; it is not a goal authoring system.
Can a client complete this tool directly?
No. The supplied configuration is practitioner-only.
Is the T-score saved with the sample demo data?
No. Saving keeps the tool and supported reusable configuration, not the fictional sample ratings or demo client data.
Can the result be compared over time?
Yes. Comparable aggregate scores for the same client can be reviewed across review points when the inputs and method assumptions remain comparable.
