Computergestuurde Adaptieve Toetsen Nederlands als Tweede Taal in de Volwasseneneducatie

In the education of Dutch as a Second Language, frequent use is made of paper-based tests. In this contribution, we describe how an adaptive test was constructed on the basis of an item bank which already existed and test items that were written specifically for use in a computer test. Several advantages of a computer adaptive test are dealt with. We describe how field tests for Reading and Listening were carried out in order to scale the test items, using a One Parameter Logistic Model. In addition, research that was carried out on the basis of questionnaires clearly demonstrates that the computer test is satisfying for the students, as test results are immediately available to them. Teachers seemed to need some time to get used to the computer test, but they also stated that the computer test accurately reflected language levels of their students.
