Abstract Contrary to conventional educational testing, in so-called dynamic assessment subjects are allowed to consult help during testing or are offered prior training. The differential results of both testing procedures are sometimes ascribed to the idea that dynamic tests reflect the breadth of the zone of proximal development on top of independent achievement. Alternative explanations claim that conventional tests are more strongly biased towards various characteristics of persons, which have a negative influence on performance, when compared to dynamic tests. In this study, it was hypothesised that static as well as dynamic assessment is biased towards anxious tendencies of subjects, but the former more strongly than the latter. In order to investigate this supposition, the performance of subjects on dynamic and static tests was systematically compared and related to measures of test anxiety in a longitudinal experiment. In the experiment, repeated measures of independent mathematics achievement as well as mathematics learning potential were gathered among students of secondary education in the Netherlands. Prior to every mathematics test, subjects filled out a test anxiety questionnaire. After every mathematics test, subjects filled out a general state anxiety questionnaire. The participating subjects were students from secondary education, either preparing for higher vocational training or university, aged approximately 15 years on average. The results of the experiment showed that lack of self-confidence is an important constituent factor of test anxiety, apart from worry and emotionality. The data supported the assumption that such testing procedures are less biased towards anxiety than conventional tests, but it was not established that dynamic testing procedures render results that are not biased by test anxious tendencies.
