We expect that the analyses will provide guidance for formal discontinuation criteria, as well as potential “start” and “stop” points by age for the tests. For now, the guidelines for discontinuing a test are to be aware of difficulty level and to stop a test or a section of a test where the following items are increasing in difficulty. For example, on 01 Visual Praxis: Designs, the items in Part 1 are presented in order of difficulty, with Part 2 starting over with more simple items. Therefore, on that test, if a child received 2 or 3 0’s in a row (we expect that testers can use judgement regarding the reason a child is scoring 0, (e.g., ability versus momentary distraction or motivation and thus decide whether to wait for a 3rd 0 or not). On test 02 Visual Perception: Search, all items are presented in order of difficulty (i.e. there is not a section that starts over with easier items) therefore, if a child scores 0 on 2 or 3 items the entire test can be discontinued.
On the EASI Scoring Program (ESP), items not administered should be entered as “skipped”.
