Yes, you can compare ImPACT test records of differing versions against one another. If all test records are version 3.8.0 or higher, they will use the new normative data set and all normal calculations will be performed. If some records are older than version 3.8.0, those records will use the original normative data set and RCI calculations will not be performed.
If I administer a post-injury test with ImPACT Version 4, can I compare it to a test taker’s baseline from an older version of ImPACT?
