Compiling a special battery of tests that should serve investigations for certain situations
or fields of activities involves a previous selection of the criteria for psychological
measurement and then deciding from the complete GATB upon those tests that will serve
the purpose agreed with the counsellor. Analysing the correlations of performance in tests
with the criteria considered decisive in the investigated field makes the choice.
Manual scoring is done with a transparent grid placed on the answer sheets. The time for
getting row scores in a subtest – assuming the right answers – does not exceed 5 minutes.
The row scores for each test are converted into standard scores with a mean of 100 and a
standard deviation of 20.
Incorrect or no answers are not penalized; only more than one answer to an item is
considered incorrect and not counted as right answer.

For practical reasons, the occupations GATB operated with have been classified into five
large categories (families) – depending on levels of complexity, responsibility, education
and training. It was considered more appropriate to work with a smaller number of
categories when clients are advised, since the risk of error is reduced and at the same time
the beneficiaries of counselling are warned of the multiple options they have, of the
professional mobility opportunities, or continuing learning is suggested to them.
GATB is used (both for the client and the counsellor) to:
- discover the aptitude related strengths and weaknesses of beneficiaries, when
it is a question of opting for an occupation; - identify the need for additional learning and training in order to fill a position
in the future; - evaluate the degree of realism in one’s professional goals with those of
others; - discover occupational domains compatible with the client’s aptitude
structure; - compare one’s aptitudes to those of people in certain positions;
- anticipate professional success in a certain occupational area.
