The success of the Nurse-Family Partnership (NFP) program has been documented in the United States, most recently in a study released July 24/17 by James Heckman, a Nobel laureate economist at the University of Chicago. By ages six and 12, children whose mothers received NFP were healthier and had better cognitive and social and emotional skills, he found. Mothers also had better mental health and parenting skills as a result of the program.
