Today's psychological measurement depends almost exclusively on the "standardized test." A certain amount of non-standardization, however, exists in the administration of any standardized test, with the amount unknown for any given test score. Time limits on tests pose a bigger problem since another variable is introduced, pressure. Test taking motivation must also be considered. The test could be too easy or too difficult, thus boring or frustrating the individual. Reliability is also a difficulty, since there is no true reliability computed for an individual. Proper application of computer technology permits a solution to many of the problems raised by standardized tests. The tests would be individualized, with items of known difficulty grouped or stratified by level of difficulty. The testing situation could be tailored to fit an individual's preferences and/or abilities and disabilities. Administrative fluctuations and test taking motivation could be eliminated. Individualized item sequence would tailor the test to the individual, as far as difficulty is concerned. Through the item sequence, reliability would become more accurate, as the computer could more exactly pinpoint levels of difficulty. (KJ)
