A capability approach was used to identify and synthesise research studies about online students with disabilities in primary and secondary school (aged five to 18 years) in an attempt to describe the experience from an empirical perspective. A capability approach is intended to maximise agency and can be used to describe the extent to which individuals are able to use limited resources to build a satisfying and enjoyable life. In this analysis, a derived capability set was used to narrow the larger body of research about primary and secondary students in online education in order to consider only studies that described ways in which students successfully used online education to maximise agency. The derived capability set was: autonomy, judgement, practical reason, affiliation, high school graduation and a desire to help others. A method for deriving the capability set and ways in which a capability approach fails to describe this experience are discussed.
