Differential Aptitude Test (DAT)
The differential aptitude test (DAT) evaluates the ability to acquire a set of cognitive skills such as reasoning (verbal, abstract, and mechanical), spelling, numerical ability, perceptual accuracy and speed, and space relations. The results of this tool can help identify strengths and weaknesses, educational options, and career paths. DAT has been in use since 1947 and since it is strictly timed, many takers cannot finish the whole assessment. This was authored by George Bennett, Harold Seashore, and Alexander Wesman who aimed to look into the aptitude of senior high students.
