Goal Attainment Scaling (GAS): Measuring Progress

Goal Attainment Scaling (GAS) is a practical method for scoring how well a patient's specific goals are met during their therapy or intervention. This tool lets clinicians and clients work together to select goals that really matter. It focuses on measuring individual progress rather than comparing results to a standard norm. Each goal gets rated on a scale with five levels to track success. A score of zero marks the expected outcome, while negative two shows the baseline and positive two indicates a much better result. This range helps capture even small changes in function over time. Widely used in rehabilitation and mental health settings, GAS is flexible enough for many conditions. You can calculate an overall T score to summarise multiple goals into a single number. It is a smart way to prove if a specific therapy plan is actually working for the person involved.
