How to find psychological tests

Catalogue of Psychological Tests

The Library Learning Centre Roeterseiland Campus has a catalogue of psychological tests and questionnaires. They can be requested at the desk of the Library Learning Centre, but only staff members of the departments of Psychology and Educational sciences can borrow them, as well as individuals who are authorised by a member of staff of these departments. Authorisations may be given by e-mail


The PsycINFO database has various options to search for tests.  There is a tutorial in Dutch.


The COTAN test database contains descriptions and reviews by COTAN (Dutch Commission for Test material of the Dutch Institute of Psychologists) of the quality of psychodiagnostic instruments. This database has extensive search functions.

Mental Measurements Yearbook (MMY)

The Mental Measurements Yearbook contains descriptions and reviews of the quality of psychodiagnostic instruments of the Buros Institute of Mental Measurements in the USA. It is recommended to check Test Reviews Online if a test has been reviewed by them. In the library you can then study the print version of the Yearbook.

The Test Link database contains the data of more than 25,000 measuring instruments from the ETS (Educational Testing Service) in the USA and is therefore the largest database in this field. Most of the tests in this database are constructed by authors from outside the ETS and downloading for research purposes is usually not free.
