aeh, sorry I did not state my question clearly. Was wondering if the tests are overlapping in mandate. Since they are both knowledge tests (as opposed to IQ). Would most schools use them interchangeably for evaluation?
Thanks.
Got it.
No. They should not be used interchangeably. The floor and ceiling are much narrower on the ITBS than on individually-administered achievement tests like the WJ, WIAT, or KTEA, and do not adapt well to the level of the student. Also, since they do not involve direct, face-to-face interaction with an examiner, the ITBS are much more subject to attentional and engagement effects. Individual NRTs allow for querying, multiple breaks, probing/testing of limits, etc., which ITBS, CAT, SAT10, etc. do not.
