Depending on the subtest, the respondent’s answers are given either in multiple-choice format or as automated free responses. In the individual subtests the items are sometimes presented adaptively in the form of a power test and sometimes in linear form with a time limit. The five ability factors are assessed by means of the following subtests:
- Numerical inductive reasoning: Identifying the rules on which a number sequence is based and continuing the sequence.
- Figural inductive reasoning: The ninth field of a 3x3 matrix of symbols must be filled with one of eight possible symbols in accordance with the underlying rules.
- Crystallized intelligence:
- Word meaning: A synonym for a given word must be selected. The test uses a multiple-choice format.
- Verbal fluency: An unordered series of letters must be turned into a meaningful noun.
- Arithmetical competence: The respondent must perform a computational task in his/her head.
- Arithmetical flexibility: A given equation must be solved by inserting the correct arithmetical operations.
- Spatial ability: The respondent states whether one of six comparison cubes represents a given test cube from a different perspective.
- Long-term memory: This subtest consists of a memorizing phase, an intermediate phase and an adaptive test phase; it involves remembering information about fictitious people.
