About ImPACT Testing

ImPACT's Test is computerized and takes about 25 minutes to complete. ImPACT recommends that it be administered by an ImPACT trained athletic trainer, school nurse, athletic director, team doctor or psychologist. Baseline tests are suggested every two years. If a concussion is suspected, the baseline report will serve as a comparison to a repeat ImPACT test, which professionals can use to assess potential changes or damage caused by a concussion. The management of concussions should only be conducted by trained medical professionals. To achieve this, ImPACT is expanding reach to manage concussions through a growing national network of several hundred clinical professionals who are Credentialed ImPACT Consultants (CICs).

ImPACT Features


The test modules consist of a near infinite number of alternate forms by randomly varying the stimulus array for each administration. This feature was built in to the ImPACT Test to minimize the "practice effects" that have limited the usefulness of more traditional neurocognitive tests.

The program measures multiple aspects of cognitive functioning in athletes, including:

  • Attention span
  • Working memory
  • Sustained and selective attention time
  • Response variability
  • Non-verbal problem solving
  • Reaction time
