Mr Alexander writes:
The Differential Aptitude Tests (DATs) are designed for use in
educational and vocational guidance and are used by school counsellors,
personnel officers, psychologists and all persons concerned with
assessing the intellectual characteristics and educational or vocational
aptitudes of adolescents. This battery of tests has been adapted for
use in Irish schools.
The rationale behind the Differential Aptitude Tests is that since
different kinds of abilities are useful in different jobs and in
different school subjects, a battery giving measures of several
abilities is likely to be more useful than a test giving a single
general ability score. There are eight subtests: Verbal Reasoning,
Numerical Ability, Abstract Reasoning, Space Relations, Mechanical
Reasoning, Clerical Speed and Accuracy, Spelling, and Language Usage.
Scores can be used to produce a profile showing a pupil's strengths
and weaknesses. A combined Verbal Reasoning and Numerical Ability score
can be used as an index of scholastic ability.
