Paediatric Myalgic Encephalomyelitis (ME)/Chronic Fatigue Syndrome (CFS) is a disabling condition. Schools play a key role in adolescents' experiences with managing ME/CFS. However, little is known about the experiences of adolescents with ME/CFS (and their families) in schools. This paper is an incidental qualitative study, which combines data from two independent ME/CFS studies: study 1 researched ethnic minority adolescents with ME/CFS; study 2 explored Acceptance and Commitment Therapy for adolescents with ME/CFS who had not recovered after one year. Participants included: adolescents with ME/CFS; their families; and medical professionals (ME/CFS specialists and non‐specialists). Adolescents, their families, and ME/CFS medical professionals were recruited from a UK specialist paediatric ME/CFS service. Non‐ME/CFS medical professionals were recruited from the same region. Semi‐structured qualitative interviews and focus groups were undertaken. Participants' views on schools from each study were combined and thematic analysis was used to identify themes. Fifteen adolescents with ME/CFS (11–17 years old), sixteen family members, and ten medical professionals (GPs, school nurses and ME/CFS specialists) were interviewed. Four key themes were found: (1) adolescents identified school was important for aiding ME/CFS recovery, especially educationally and socially; (2) families described varying levels of support from schools and local authorities with help managing ME/CFS – some described significant practical and emotional difficulties to accessing education, whereas others recounted examples of positive supportive strategies, particularly when teachers had previous experience or knowledge of ME/CFS; (3) parents thought three‐way communication between schools, healthcare and families could improve support; (4) participants felt schools were an appropriate place for knowledge building and raising awareness of ME/CFS amongst teachers and pupils, to aid improved supportive measures. In conclusion, this paper provides rich data that highlights the importance of education and the realistic fears and hurdles for adolescents with ME/CFS remaining engaged in education and the impact on their future. Some families described positive strategies in school, which were viewed as helpful to manage ME/CFS in the classroom. These strategies could be implemented alongside knowledge building initiatives and improved communication between healthcare and education. There is a need to further investigate useful strategies and determine how teachers can be best supported in implementing them.
