How do I interpret ImPACT Quick Test composite scores?

The composite scores for ImPACT Quick Test® represent performance in 3 separate domains. Performance is expressed as a percentile score based on the normative sample. As with all percentile scores, the range is 0-99 with lower scores representing less optimal performance. We do not offer a cutoff score or interpretive ranges. Rather, an individual’s percentile score should be considered along with other clinical information and/or testing data the healthcare provider gathers on the patient before making a removal from activity decision.
