Abstract
A detailed account is given of the development, standardization, and evaluation of The Quick Test, a brief individual intelligence test based on perceptual-verbal performance. Three single forms, each consisting of 50 word-items based on one plate with four line drawings, cover abilities from the two-year level to the superior-adult level. Three to ten minutes are required to administer the QT to any person who can see the drawings, hear or read the word items, and give a yes-no signal. Standardization was based on the responses of 458 children and adults, a sample controlled on a simultaneous quota basis for age, sex, educational level and own or father's occupation. Single forms and combination forms (1+2, 2+3, 1+3, 1+2+3) were found to be highly reliable (.66 to .95). These estimates were corroborated in several independent studies (N = 111), as were validity estimates (.77 to .96, correlations with the revised Stanford-Binet and the Wechslers). MA, IQ, and percentile norms are included as well as a discussion of practical problems in testing, suggestions for minimizing such problems, and ideas for further research. It is concluded that the QT is quite satisfactory for school, clinical, and research use, and since the QT shows strong correlation with the Full-Range Picture Vocabulary Test, the two tests can be used interchangeably.
