In 1987 the Challenge Day Begins: As graduates of the California public school system, Yvonne and Rich experienced first-hand the costs and consequences of bullying and isolation in school. Committed to making things better for their own children, they founded the innovative and award-winning Challenge Day Program in 1987.

Research shows that there are significant beneficial outcomes from social and emotional skill-building, including positive attitudes about self, school, and civic engagement. Improvements are seen in social behaviors, conduct problems and academic performance.

Challenge Day program activities are centered on five tested competency areas: self-management, social awareness, self awareness, relationship skills and responsible decision-making

In Nederland is het tv-programma 'over de streep' gebaseerd op Challenge Day. Meer info op Wikipedia.
