How long do mandated parenting classes last?

Court mandated parenting classes, also known as PIP, last around four hours.  In Arizona every parent of a natural or adopted un-emancipated minor child who files for divorce, separation, parenting time/custody, or any paternity proceeding in which a party has requested that the Superior Court determine custody, specific parenting time or child support must attend a Parent Education class. The Court may order attendance when parents are involved in a child support case or seek to change an order for custody or parenting time.
