The purpose of the positive assessment, which is to reassure and provide direction, is the same for working with children and adults.
In a child based context, we aim to ensure that children use the experience to engage at school and feel hopeful that with their effort their are viable career options for them afterwards. We want to connect them with their inner genius or inner competence and also let the support systems around them know how to encourage them through their education to a bright, viable future as adults.
For adults, positive assessments often come too late. They have been through education, which is heavily weighted towards verbal and processing speed skills, thinking that they lack talent. We want to redirect their attention to what they can do, and remind them that no matter what their experience has been so far, they have value as member of a community and their are roles that play to their strengths.
