Why ITB tests?
Good success predictors

ITB tests allow reliable prediction of study success. This so-called “prognostic validity” has been verified for numerous ITB tests in longitudinal studies. The field-specific test modules often possess better prognostic accuracy than the general test modules. The correlations between the test results and final exam grades generally range between .30 and .50, and are thus outstandingly good in international comparison.

Low trainability

Success test performance should not depend on how much time and money is invested in the preparation. This is why ITB tests use complex problem-solving items that are less easy to train than classical test-item formats such as those used in intelligence tests. The items represent miniature simulations of requirement situations and call for the interaction of several skills which, to an extent, can be used compensatorily to solve a problem. This makes it possible to measure stable abilities – and not how much money and time was spent on the preparation.

High legal certainty

ITB tests fulfil all the legal requirements and will stand up in a court of law. The tests are developed and evaluated according to national and international standards. Personal data is stored securely and exclusively in accordance with the strict European data privacy regulations on servers in the EU. There has never been a successful university admissions lawsuit against a test from ITB.

High relevance to real requirements

All ITB tests are developed on the basis of analyses of the requirements and individually tailored to the respective purpose. Field-specific academic aptitude tests, for example, are developed in collaboration with experts in the respective field. In terms of content, the test items are embedded in the respective study field so that the relevance to the subject is clearly recognizable and the tasks are especially motivating for the test-takers. In addition to the actual measurement of their abilities, the participants also learn what requirements they can expect to face in their studies.

Our tests are developed on the basis of the Blossom Model of Academic Aptitude.
