Conclusion Of Impact Test Agregate

The Derived Scores | ImPACT Version 4

The Two-Factor Score (speed and memory) provides an additional summary score approach for interpretation of the test data. Research has shown that in addition to the existing four Composite Scores that have historically been used to describe the ImPACT test results, a Two-Factor Score can also provide a valid approach to interpreting the data.
