Transition has been defined as the process of changing from one state or condition to another and a period of such change (Oxford English Dictionary, 2012). This module will explore transitions that occur in children's and adolescents' lives, including ?Vertical transitions?, described as ?developmental and predictable? and including moving on from one setting to another at the appropriate stage in education/life; ?Horizontal transition?, described as the movement between activities during the course of a normal day. The module will also explore transitions that result from migration, changes in the family structure, and bereavement.
