About the methodology
The IST (Intelligenz-Struktur-Test) by Rudolf Amthauer is a multifactorial test assessing various aspects of cognitive abilities. The methodology is based on the concept of intelligence structure, according to which general intelligence consists of several relatively independent components: verbal, numerical-mathematical, spatial, and mnemonic.
The test is widely used in professional selection, career guidance, and educational psychology.
IST has undergone numerous standardizations and validations across different cultural contexts, demonstrating high reliability (test-retest reliability r = 0.83–0.91) and construct validity. This online adaptation presents tasks modeling four main IST subtests: verbal completion, analogies, arithmetic problems, and number series.

Frequently asked questions
What does this test measure?
The Amthauer IST assesses four components of intelligence: verbal (understanding language constructs and analogies), numerical-mathematical (arithmetic operations and number patterns), spatial (mental manipulation of figures), and mnemonic (short-term memory capacity).
Who is this method designed for?
The IST is designed for people aged 13 to 60. It is widely used in professional selection, career guidance for high school and university students, and educational psychology.
How long does it take to complete?
Completing the online adaptation of the IST takes about 35 minutes. It is recommended to take the test in a calm environment without distractions.
How accurate are the results?
IST is one of the most valid psychometric instruments. The test-retest reliability of the original method is r = 0.83–0.91. This online adaptation is based on IST principles but does not replace professional assessment.
Can I prepare for the test?
Practicing similar tasks can improve speed but does not affect the baseline level of cognitive abilities. The test is aimed at assessing current intellectual potential.
How is IST different from an IQ test?
IST does not just give a single IQ score but breaks down intelligence into components. This allows you to see strengths and weaknesses: for example, high verbal intelligence with average spatial ability.
