Background ACP


As a leading tool in personality research, ACP was developed over twenty years by Dr. Harald Hauschildt and his team. It exceeds the high standards of quality criteria on test methods of this kind and also includes new developments, e.g. in the areas of differentiation, the calculation of development potential and anti-counterfeiting security, which set new standards.

ACP is based on the globally recognized "Big Five" research, which has divided the proven 4504 different personality traits into five major groups through factor analysis.

At ACP, the Big Five research has been further developed and refined with supplements. The less neutral terms, such as neuroticism (emotional lability, vulnerability), which inhibit non-judicious use and acceptance in a sensitive context, have been neutralized in:

Alpha (active maker)

Beta (contact-oriented teamer)

Gamma (thorough planner)

Delta (stable optimist)

Theta (cosmopolitan pioneer)


The core factors alpha, beta and gamma are often clearly perceptible, while the modulation factors delta and theta influence these and thus provide information about the quality of and the direction of the characteristics of the core factors.

Due to the high degree of differentiation of the profiles, the results of the ACP allow far safer statements than the often overestimated small profiles of other providers, whose results leave much room for interpretation due to a few measured values.

The ACP provides pinpoint statements about the strengths of a person and how they can affect different interactions and offer a variety of uses through their practicality
