This code directory lists various levels of severity associated with each type of impairments and/or functional limitation listed in CD.DR.01 ImpairmentType/Functional LimitationType. It serves as a guide for interoperability between disability and SP-MISs. The scale and level of severity of impairment can vary between countries depending on the legal framework and disability certification related regulations. The scale suggested here is drawn from the ICF check list and the WG sets of questions.
