Differential Aptitude Tests – Forms R, S, K and L (DAT)

K. Owen & H.N. Vosloo

The Differential Aptitude Tests are a series of differential aptitude tests constructed to assess some facets of intellectual functioning. Included among these are the following: abstract reasoning ability, language ability, processing speed, mechanical insight etc. The kind of information obtained from the DAT can, along with information on interests and previous experience and achievements, facilitate judgements regarding potential success in a course or career. The particular contribution made by a differential aptitude test in vocational and educational counselling is unique and cannot effectively be replaced by measures of achievement, performance or interest. Past, present and future intellectual functioning are influenced by contextual variables and it is the task of the psychologist to interpret the profile of aptitudes accountably.

The DAT is available for the General Education and Training Phase (GET) and for the Further Education and Training Phase (FET). Two forms of the DAT are available for each of the levels of formal education. Standard forms are more suitable for general use; while the advanced forms can be used when strong academically oriented questions are at issue. The reference group for the advanced forms are those persons who had enjoyed relatively good educational opportunities. The tests may also be used with persons who left school some time ago.

The full series comprises the following:
DAT Form R – (Grades 7 to 10 Standard Form)
DAT Form S – (Grades 7 to 10 Advanced Form)
DAT Form K – (Grades 10 to 12 Standard Form)
DAT Form L – (Grades 10 to 12 Advanced Form)
DAT Form K – 2008 Edition
