Drama is often classified as the art of collaboration. It's used in groups of mixed ability because it can act as a bridge for those with special needs alongside their peers. In essence, enabling people with difficulties and differences to work together. Creating a new form of relationship.
However. One thing. In my opinion, that mindset comes the danger of assuming that drama is 'the inclusion subject'. This can devalue the contribution theatre brings to any form of academic work.
For example, it can lead down these roads: - A devaluation of the achievements of all drama students due to it being an 'easy' subject for all - The mis-teaching of drama as always accessible and achievable. - The view that the arts do not require basic skills/talents or any work to develop - The segregation of students with additional/special needs who do not find drama lessons automatically accessible and intuitive.
None of this is beneficial for those with special needs; it's safer to come in with a fresh mindset based off of the individuals. Especially as drama can be a very personal artform that helps people grow.
