The transition to secondary school is a common cause of stress and anxiety, which can be exacerbated by the innate characteristics associated with Asperger syndrome (AS) and high-functioning autism (HFA). This study aimed to explore experiences of the transition to secondary school for students with AS/HFA from the parental perspective. Seventeen parents of children with AS/HFA from the north of England completed an online questionnaire about their child's school transitional experience. Responses indicated that there were a number of factors that influenced the experiences of pupils with AS/HFA at school and the preceding transition, including anxiety, bullying, friendship and support at school. Girls with AS/HFA presented with unique issues not commonly seen in the male dominated condition. The transition to secondary school was seen to encompass a number of difficulties for students with AS/HFA. Health and educational services can learn from the experiences explored in this survey in order to inform future practice.
