Advances have been made in testing optometrists' clinical skills, particularly with the use of simulation techniques. Further research into these techniques will probably receive the most attention, although a shift in research emphasis from correlational studies of test validity and reliability to test development studies is needed.

Valid assessment of professional competence has proven to be an elusive goal. Objective tests, direct observation of performance, overall ratings of competence, and simulations have been tried and found wanting in one way or another. Objective test items are criticized as being unrealistic and therefore invalid. Direct observation tends to be very…

In providing an alternative view to the previous article by Ward (TM 508 880), the author notes problems associated with adaptive testing, diagnostic testing, testing embedded in instruction, and testing through simulations. (BW)
