Health classification schemes not only affect funding of speech-language pathology services but the terminology used in the classification affects the way the profession communicates externally to its stakeholders and internally within the profession. This paper describes the classification scheme of the World Health Organization's International Classification of Functioning, Disability and Health (ICF). While the conceptual framework of the ICF has been established within the profession, the detailed classification scheme is becoming increasingly important to speech-language pathologists. The implementation of the classification worldwide presents many opportunities for speech-language pathologists. Details of the ICF, however, continue to be ''work in progress,'' particularly in areas highly relevant to speech-language pathology such as the differentiation of the Activity and Participation components and their qualifiers. This uncertainty, together with other limitations, needs to be acknowledged by the profession. A research agenda is proposed that aims to place the speechlanguage pathology profession firmly at the forefront of ICF developments, so that the full scope of the profession's work is suitably acknowledged in the future.
