The School Setting Interview (SSI) was developed to examine the level of student-environment fit of students with physical disabilities and facilitate the planning of occupational therapy interventions in school. SSI is specifically developed for students with physical disabilities who have some type of motor dysfunction. Although it can be used for students with other types of disabilities. SSI is a client-centred assessment intended for students from approximately 10 years of age and older. The SSI includes 16 items (i.e. questions) concerning everyday school activities where students with disabilities may need adjustments to be able to participate. Each item is scored using a four-step rating scale that enables the student and the therapist to jointly decide the level of student-environment fit.
SSI is based on the Model of Human Occupation (MOHO) and the principles of client centred practice. According to the International Classification of Functioning, Disability and Health (ICF), environmental factors have an impact on body functions and body structures as well as activities and participation. The SSI explicitly focuses on how environmental factors influence activities and participation in school.
