DAT is highly adapted by Indian psychologists to suit local recruitments. This battery is mainly meant for an occasional and vocational counselling of students.

It is widely used nowadays in Indian employment services.

Test of mechanical and clerical aptitude: This is included in the multiple aptitude batteries. The test of mechanical aptitude is solely concerned with the mechanical information, mechanical reasoning or mechanical comprehension.
