President, legal members, medical members and ordinary members and determinations will be  taken by panels, consisting of those members, appointed by the President.  Schedule 2 sets out how a health care professional is to assess a person’s degree of disablement.  Disablement means the loss of physical or mental capacity caused by an injury or illness, whether  mental or physical. It is assessed by comparing the person with the disablement with an average,  healthy person of the same age and sex, ignoring such matters as occupation. The degree of  disablement must be expressed as a percentage.  Schedule 3 makes consequential amendments.  A full impact assessment has not been produced for this instrument as no, or no significant, impact  on the private, voluntary or public sector is foreseen.  © Crown copyright 2020  Printed and published in the UK by The Stationery Office Limited under the authority and superintendence of Jeff James,  Controller of Her Majesty’s Stationery Office and Queen’s Printer of Acts of Parliament.  37
