Since 1980, the American Occupational Therapy Association has collected its official documents-must-have information for occupational therapy students and practitioners-into one handy, frequently updated reference work. The 20th edition continues that tradition and includes concept papers, guidelines, position papers, roles papers, specialized knowledge and skills papers, standards, statements, and information on the American Occupational Therapy Foundation. This text is a valuable resource for occupational therapy practitioners and managers and provides a solid grounding in the profession for students.
