The teachers I interviewed overwhelmingly perceived challenging behaviour in terms of disruption to their lessons. What emerged from the interview findings was that disruption to the learning process was what the teachers found most challenging because it diverted the teachers from being able to carry out their role. Quite simply their perception was that they were sometimes prevented from doing their job. This disruption was created in a variety of ways, but the four most common were firstly, attention seeking (mentioned by 5 teacher participants), secondly defiant behaviour (mentioned by 5 teacher participants), thirdly restlessness and refusal to work (mentioned by 4 teacher participants) and fourthly physical aggression (mentioned by 3 teacher participants). The least challenging behaviours as perceived by the teachers interviewed were – immature behaviour (“crying over every little thing and complaining about one another to the teacher” mentioned by 4 teacher participants) and separation anxiety (“throwing a tantrum in the morning while saying goodbye to mum or dad” mentioned by 3 teacher participants).
