Home visitors may provide information on childcare and social services, help parents in crisis and model problem-solving skills. They may help implement the preschool/school curriculum at home or provide a curriculum of educational games designed to improve language, development and cognitive skills. In most cases, such support is offered to families on a voluntary basis. Families who are eligible for the program may decide for themselves whether or not they want to participate. There are no penalties if they decide against it or against continuing with the program.
