Test-battery for children and adolescents measuring complex as well as basic cognition (“intelligence“). It aims for a profile interpretation with respect to many abilities (pragmatic approach of testing intelligence); partially with thematic reference to Wechsler. It applies so-called “adaptive” item selection according to the testee’s level of proficiency for ten subtests and one add-on-test, which serves for high economy, i.e. high accuracy of measurement with relatively few items. There are tests with “verbal-acoustic“ tasks: Everyday Knowledge, Applied Computation, Immediately Reproducing-numerical, Producing Synonyms, Verbal Abstraction, Social Understanding and Material Reflection, Storing by Repetition-lexical, Producing Antonyms. There are tests with “manual-visual“ tasks: Competence in Realism, Social and Material Sequencing, Coding and Associating, Anticipating and Combining-figural, Analysing and Synthesising-abstract, Formal Sequencing, Immediately Reproducing-figural/abstract, Learning and Long-range Memorising figural/spatial, Recognition of Structures-visuo-motoric. All twelve sub- and five add-on-tests of the AID refer to deliberately defined abilities. The items of most of the subtests capture a wide range of performances and due to adaptive testing, administration is very economic. Furthermore, some subtests can be administered in many forms, adapted to suit the problem. By default, for ten subtests (and one add-on-test), item groups are administered step by step in a way that suits the testee’s performance in preceding item groups. Additionally, conventional testing is also possible, either specific or unspecific to the testee. Five subtests (and one add-on-test) may even be administered (adaptively) as short forms, and there are proper parallel forms for eight subtests in case a second test administration takes place after a short period of time. Due to adaptive testing, resulting adequate achievement motivation of the testee can be expected. The “(lower margin of) intelligence quantity“ – that is the cognitive minimal ability – acts as the best global index of cognitive abilities, complemented by the range of “intelligence“ – that is the diversity of the ability spectrum. However, most preferable is a profile interpretation which interprets the T-scores of all subtests in relation to one another. The Diagram for screening partial performance weaknesses refers to specific developmental disorders or learning disabilities and the Supplemental sheet for categorising the testee’s “attitude to work” acts as a qualitative assessment of the testee’s working and contact behaviour. The availability of instructions for non-verbal administration for six sub- and three add-on-tests enriches the field of possible application of the AID.
