What it measures:
The General Reasoning Test Battery assesses three domains of ability that are relevant to work and study: Verbal Reasoning, Numerical Reasoning and Abstract Reasoning. Of these, Abstract reasoning is the least affected by education and cultural background.
Target population:
This battery is recommended for persons with an educational level of grade 9 and upwards. It can be used for selection, guidance or development.
Logistics considerations:
The tests are brief, and the time taken for administration (not counting instructions) is less than half an hour for the whole battery. Instructions need to be given with care though, and if the test is properly administered with due attention to examples and instructions, it should take between 45 minutes and an hour to administer the whole battery with all three subtests. The tests can be administered using pencil and paper, online or on-screen using an off-line computer via the GeneSys integrated assessment software.

Published Date | Written by Nanette Tredoux | | | Hits: 350
The Graduate Reasoning Test Battery is intended for selection of persons for specialised positions that are particularly intellectually demanding and demand high level training and education. As with the General Reasoning Test Battery, it assesses Verbal, Numerical and Abstract Reasoning, but at a considerably higher level of difficulty.

Critical Reasoning Test Battery (CRTB2)
Published Date | Written by Nanette Tredoux | | | Hits: 533
The Critical Reasoning Test Battery assesses numerical and verbal critical reasoning, which is a combination of comprehension and critical thinking. Test items take the form of scenarios with either verbal or numerical content. For the verbal test, respondents must judge the truth of deductions made from the paragraph contents, and for the numerical tests, they need to answer multiple choice questions based on the scenario and supplied figures. The scenarios are all relevant to the business world, which makes this test particularly suitable for occupational selection. The difficulty level is suitable for graduates and persons with some experience in a managerial role.
