Child Occupational Self Assessment (COSA)
What It Measures
The Child Occupational Self-Assessment (COSA) asks a child two questions about each of 25 everyday activities: how well do you think you do this, and how much does it matter to you? The activities span home, school, and community — keeping your body clean, finishing your work, making friends, choosing what you do.
Pairing competence with value is the design. An activity a child struggles with and does not care about is a different problem from one they struggle with and care about deeply, and only the second belongs at the top of a goal list. There is no total score. The therapist reads the pattern using Model of Human Occupation theory. Three formats exist — a form with picture cues, a form without, and a card sort — chosen to match the child.
