The starting point for the present "3rd generation", AID 3 (Version 3.1), of the AID test battery first published in 1985 was not so much the obligation for a new calibration (standardization) according to DIN 33430, but rather the effort to take into account the social changes that have occurred in the meantime and consequently to make changes to the content of a large number of tasks. In addition, the test battery was to be expanded to include new sub-tests and additional tests in order to better meet the demands of practice. The result is a test battery with a modernized content concept for measuring cognitive abilities. And even more than ever, an attempt is being made to test as economically as possible in the sense of minimum time expenditure with maximum measurement accuracy. 

The "verbal-acoustic" abilities are measured: everyday knowledge, applied arithmetic, immediate reproduction-numerical, finding synonyms, abstracting functions, social comprehension and factual reflection as well as the "manual-visual" abilities: certainty of reality, social and factual consistency, coding and associating, anticipating and combining-figural, analyzing and synthesizing-abstract, formal consistency; In addition, there are the additional tests Immediate reproduction-figural/abstract, Memorization through repetition-lexical, Learning and long-term memorization-figural/spatial, Finding antonyms, Structuring-visumotor.

All twelve subtests and the five additional tests of the AID 3 are based on operational definitions that specify the abilities measured in each case. The comprehensive test material of most subtests, which is designed to be child-friendly and thus to motivate children and adolescents to participate joyfully in the testing, allows a wide range of abilities to be measured unidimensionally.
