What does Head Start provide?

Head Start provides comprehensive early childhood education, health, nutrition, and parent involvement services to low-income children. Option A is incorrect because Medicare and Medicaid services are not part of the Head Start program. Option C is incorrect because Head Start specifically focuses on early childhood education and services, not healthcare resources and service administration. Option D is incorrect because Head Start does not provide dental insurance models, but rather a range of health services for children to promote their overall well-being.
