Abstract The principles of the Tanner‐Whitehouse‐Healy system for assessing skeletal maturity will be described and in particular the statistical basis for the scores given to each stage of each bone in the hand and wrist. The uses of the system, particularly in clinical cases, will be discussed together with reliability of the ratings. A revised system will be presented in which a part of the stages are amalgamated and the possibility of dropping some of the bones will be discussed. General discussion will be invited on the logical basis for selecting certain stages of certain bones as superior to others as assessors of maturity.
