„Upon arrival in the Netherlands, primary school students usually spend 30-40 weeks and secondary school students two years in specialised classes for newcomers. […] Every 10-13 weeks, student development is evaluated. Depending on the progress achieved, students continue to stay in specialised classes or move to mainstream settings.“
