Johnson's "War on Poverty" administrative team campaigned for committee members to join the War on Poverty efforts to create and develop programs for children born into poverty (Zigler, 2003). Poverty based programs, such as the Head Start program, continue to put into place proactive measures to increase preschooler's cognitive development, and social skills. Research has suggested if a preschooler who qualifies for the Head Start program but does not attend early interventions has an 80% chance of dropping out of school, an increased tendency for teenage pregnancy, typically lacks foundational skills in reading and math, commonly fails state and federal assessments, and lacks continued parental involvement (Vanderstaay, 2006). The following overview discusses the historical aspects of the Head Start Program, Federal Poverty Guidelines, early childhood studies, High/Scope Perry Preschool Study, the Abecedarian Study and the advantages/disadvantages of the Head Start Program.
