Colorado is pulling off a culture shift in child-support collection, a new era far from the 1990s’ call to track down “deadbeat” parents, freeze their accounts and suspend their driver’s licenses. The state has renamed its “Division of Child Support Enforcement” to the kinder and more constructive “Child Support Services.” And under an experimental program, it’s helping parents behind on child-support payments find jobs, fight alcohol and drug addictions, and reconnect with their kids. The five-year program — aimed at parents who want to pay but don’t have the money — has been so successful it has attracted national attention as a model for other states.
