There are two main differences: 1. You do the entire exam on the computer and 2. the level of Dutch is higher (B1-level). When you pass the Korte Vrijstellingstoets, you will receive a certificate that exempts you from the otherwise compulsory regular 'Inburgeringsexamen'.
The examThe exam takes 45 minutes. You have to answer questions about short videoclips that you will be shown. On average, an exam consists of 30 questions but the exact number can vary per exam. You need to score at least 74% to pass the exam.
Who can take the Korte Vrijstellingstoets?The abridged exam is for anyone:
1. who has to do the Inburgeringsexamen
2. with a good knowledge of Dutch
Most people who take this exame are people who have lived in the Netherlands for a while and who, under the new 'Inburgeringswet', now have to pass a test to prove that their level of Dutch and knowledge of Dutch society is sufficient.
