Time Limits in Standardized Testing: Effects on Ability Estimation.
Garrison, Wayne M.; Coggiola, Deborah C.
The study involving 614 hearing impaired students investigated the adequacy of time limits currently followed in the administration of two subtests of the Differential Aptitude Test battery when used with young deaf students. Thirty-six students who did not complete the Space Relations portion of the battery under the timed condition, and 11 who did not complete the Abstract Reasoning subtest within the time allowed were instructed to complete the test on a separate answer sheet. Examinees' initial and revised measurements were compared for statistical equivalence in terms of the standard error of measurement computed from independent sample data. No evidence was adduced to indicate that deaf examinees would profit from an extention of testing time. (Author)
