The ICF Practical Manual provides information on how to use ICF. Anyone interested in learning more about use of the International Classification of Functioning, Disability and Health (ICF, WHO 2001) may benefit from reading this Practical Manual. The ICF is presently used in many different contexts and for many different purposes around the world. It can be used as a tool for statistical, research, clinical, social policy, or educational purposes and applied, not only in the health sector, but also in sectors such as insurance, social security, labour, education, economics, policy or legislation development, and the environment. People interested in functioning and disability and seeking ways to apply the ICF should find the contents of this Practical Manual helpful. The Practical Manual provides a range of information on how to apply ICF in various situations. It is built on the acquired expertise, knowledge and judgement of users in their respective areas of work, and is designed to be used alongside the ICF itself, which remains the primary reference.
