Dutch Committee on Tests and Testing (COTAN)

The Dutch Committee on Tests and Testing (COTAN) is a Committee of the NIP. The COTAN reviews the quality of psychological tests that are available for use in the Netherlands and raises standards for the use of psychological tests. The COTAN’s activities include monitoring psychological instruments that are applied in fields like education, human resource management, (mental) health care services, and promoting the proper use of these instruments.

The COTAN has reviewed over 800 tests, covering a broad range of psychological constructs. These include intelligence tests, educational and developmental tests, occupational tests, personality tests and so on. The aim of the Committee is to review psychological tests that are published for professional use. The tests are submitted for a review to the COTAN by test publishers and individual test authors who provide the COTAN with all the necessary documentation for the assessment.
