- CORE FS has been renormed for the first time since its release, and scoring has moved to full IRT scoring system.
- Existing CORE FS results have been rescored on the new system. Most scores went up, by a little over one SS on average.
- The previous norms were slightly deflated, but generally accurate. The new norms are the most accurate.
- 72% are unchanged or within one SS, and 98% are within two SS.
- The eight floor items added previously have been analyzed. After pruning, five were kept and now count towards your score, so the test contains up to 25 items (up from the original 20).
- Since these items should be very easy, test-taking time should be (relatively) unaffected.
- A discontinue rule has also been added in order to improve test-taking time and morale.
