As a strengths advocate I lean heavily toward helping people grow in their understanding of strengths by moving toward more granular strengths based assessments. Marcus Buckingham offers StandOut which has 9 different themes or talent groupings. Myers-Briggs offers 16 ways of understanding the uniqueness of individuals. Strengthsfinder, which Buckingham helped build during his time at Gallup offers 34 different themes and perhaps serval hundred threads.
But DISC is still a great strengths assessment. It begins with 4 very easy to understand groupings. The "Gold" Program, introduced below is specifically designed DISC for kids. If you are a parent or work with children, check it out!
