Special classes/units refer to some form of partial integration arrangements for some learners with SEN [special educational needs] within mainstream schools. These are often seen as a form of ‘special school’ within the mainstream school, particularly when they are called ‘special units’. Enrolment is often similar to that for special schools. It is evident that, in these cases, special units act as a resource directed mainly to the learners and not the school staff (European Agency, 2019b, p. 22).
