How do protestant youth group ministers reach apathetic parents of religious education students?

Another year of teaching religious ed. is starting for me next week and one thing our DRE wants to emphasize, with the new diocesan norms mandating tests, of all things, is that we need more parental involvement. I'm Catholic, but I'd like to know what Protestants do to get the parents of their students more involved in their children's religious education. Mostly, how do you overcome barriers when your student's parents don't attend services or come to many church events.
