COTAN: the Dutch Committee on Tests and Testing

COTAN is the only Dutch body to assess the quality of tests. They employ a comprehensive assessment framework based on five points:

  • Theoretical basis: is the test based on a scientifically substantiated model?
  • The comprehensiveness of the manual: is the meaning and limitations of a test clear to its users? Has the development of the test been described in a comprehensive and thorough manner?
  • Norms: are the test norms based on a relevant and sufficiently large sample?
  • Reliability: are the constructs measured with sufficient reliability?
  • Validity: can the intended conclusions be drawn and do they possess predictive value?

Our most important tests have been reviewed by the Cotan and have been found to be of quality. This evaluation is relevant, especially for psychologists, because of the professional code.
