Ability Tests

Ability (or intelligence) tests are considered the most efficient psychometric tool; their results are distinguished due to their stability over time and high predictive ability. Research findings have repeatedly shown a correlation between the results of intelligence tests and success in education and work in excess of .51 (Schmidt & Hunter, 1998). Due to the high levels of validity of intelligence tests, they are among psychologists’ most frequently used instruments. 76% of psychologists in Germany use intelligence tests for diagnostics in every single case, and the rest - 24% - regularly. (Amelang & Schmidt-Atzert, 2012).

Hogrefe offers a range of intelligence tests that have been used for several decades in Germany and other European countries for staff selection and assessment.

Intelligence Structure Test (IST)

Authors of the original German version: A. Beauducel, D. Liepmann, S. Horn, B. Brocke
Authors of the Russian adaptation: S. Miroshnikov, M. Philippova, R. Chernov, S. Wildfang.

Area of application:
The IST is used for intelligence assessment in many fields, including staff selection and assessment.

General aspects:
The original version of IST was the first psychometric instrument published by Hogrefe. Since 1953, it has been used for HR selection and assessment in major German and European companies, as well as for diagnostics involving children and young people. The test has been revised and harmonised several times since its first publication. The Russian version is based on the original German tool (Liepmann et al, 2007), with due reference to the English version – IST 2000 R. (Beauducel et al, 2010).

The IST test comprises several sections, each of which measures a specific type of intelligence: verbal, mathematical, spatial, as well as logical thinking.

Each area of intelligence is assessed through three sub-tests.

  • The Verbal Intelligence sub-tests are: Sentence Completion, Verbal Analogies and Similarities.
  • The Numerical Intelligence sub-tests are: Numerical Calculations, Number Series and Numerical Signs.
  • The Figural Intelligence sub-tests are: Figure Selection, Cubes and Matrices.

When all three sections have been completed, an overall score for logical reasoning is computed along with separate scores for each area of intelligence.

Duration: 77 minutes

The computer-based version of the test is available in Czech, Danish, Dutch, English, Finnish, German, and Russian. The paper-pencil version can be purchased in Bulgarian, Czech, Danish, Dutch, English, German, Lithuanian, and Slovak.

NEW: The Kazakh and Ukrainian versions of IST are coming soon on HTS 5.

Cattell’s Fluid Intelligence Test, Scale 2 – Revision (CFT 20-R)

Authors of the original German version: Rudolf H. Weiss in cooperation with Bernhard Weiss

Areas of application:
The CFT 20-R is used for intelligence assessment in many fields, including staff selection and assessment, training and coaching, career consulting, in transport and military psychology. The target group of the test includes teenagers as well as adults.

General aspects:
CFT 20-R is a universal, time- and cost-saving test which can be applied for ability assessment among teenagers and adults from 18 to 55 years old. The test measures the general intelligence and bases on the concept of fluid intelligence by Cattell. The notion of fluid intelligence by Cattell includes the ability to identify rules, properties and relationships, process and imply them within a limited time. Since the test does not include any verbal tasks and all the tasks are of visual character, similar conditions can be ensured for test takers with different levels of language and cultural skills.

However, understanding of the verbal test instructions is necessary for providing the same conditions for all the test takers.

CFT 20-R is available in two major test forms (Short Form and Long Form) and two forms with identical tasks but additional test time. The Russian version of the CFT 20-R is standardized for the two major forms (Short and Long) without additional time. The Long form of the test contains two parts, each of them having four subtests (Continuation of sequences, Classification (odd one out), Completion of matrices and Topological deduction). The Short form of the test contains the tasks of the first part of the Long form.

It is important to test under control circumstances, which means in the presence of the test administrator.  

Short form (27 minutes)
Long form (47 minutes)
Short form with additional time (31 minutes)
Long form with additional time (51 minutes)

Design a Matrix - Advanced (DESIGMA –Advanced–)

A matrix test without distractors for measuring general intelligence

Authors of the original German version: Nicolas Becker, Frank M. Spinath

Areas of application:
DESIGMA –Advanced– is used to measure general intelligence and intellectual capacity in the upper cognitive ability range. The test is applied in many fields, including personnel selection and assessment, high potential diagnostics, coaching and career consulting.  

General aspects:
The Design a Matrix tests distinguishes itself from other ability tests due to its innovative response format. The answers for the tasks are constructed by the test taker in a computer-based testing environment. The test developers managed to avoid the problem of the classical test response format implying that the right answer is presented among a number of distractors. Thus, the probability of guessing or randomly selecting the right answer decreases. In addition, DESIGMA makes it more difficult for the test taker to use the exclusion strategy. The latter means that as many distractors as possible are eliminated on the bases of the identified rules and comparison with other tasks of the same type.

Bochum Matrix Test (BOMAT – Advanced – short version)

Authors of the original German version:  Rüdiger Hossiep, Daniela Tuck, Michele Hasella

Area of application and general aspects:

The Bochum Matrix Test (BOMAT – Advanced – short version) aims to assess cognitive reasoning ability in the higher ability ranges. Correct processing of the questions requires logical, analytical thinking and deductive reasoning. The question format – matrices consisting entirely of shapes and figures – enables this assessment to be almost entirely unaffected by prior learning, although prior familiarity with this type of question can be of some help in allowing participants to perform to their full potential. Furthermore, as with any performance test, the participant’s alertness and ‘form on the day’ may also influence the actual performance level achieved.
