This UK study aimed to elicit parental voices and school Special Educational Needs Co-ordinator (SENCo) views, to work towards a better understanding of sex-specific symptomology in females with Autism Spectrum Disorder (ASD), and identify the special educational needs of these girls. SENCos in a small local authority (LA) were sent questionnaires investigating their understanding of ASD and girls. Data were collected from 53 SENCos across the LA. Parental views were explored through a group interview with three parents of girls with a diagnosis of ASD. Results indicate that SENCos have an understanding of male presentations of ASD but lack confidence in both identifying and supporting girls with ASD. Qualitative analysis revealed the following key themes: inconsistent support, paucity of resources, parental emotion and parental initiative. Findings suggest there is a considerable gap between the needs of girls with ASD and current levels of understanding and support within educational settings.
