TEN IDEAS FOR IMPROVING EARLY HEAD START— AND WHY THE PROGRAM NEEDS THEM Nicholas Zill Early Head Start is a federal child development program intended to bolster the early learning and eventual school readiness of infants and toddlers from low-income families. The best available evidence, from a national random-assignment evaluation study, indicates that the program is not performing as intended. This paper suggests ten ways to improve the program, such as by placing more emphasis on family stability, parent- child interaction, and cognitive skills that are predictive of later achievement; using technology to help teach parents and children; employing volunteers to make early intervention less costly; and dispersing more funds to communities with greater need for the program. Nicholas Zill is a research psychologist and independent consultant based in Washington, DC. Prior to his recent retirement, he was Director of the Child and Family Study Area at Westat. In that capacity, he headed several national surveys and assessments of Head Start program performance. 40 ZILL Early Head Start (EHS) is a federal program for the child. Both small-scale observational intended to address the same social problem research4 and large-scale survey studies5 that the larger and better-known Head Start have found that young children in low- program addresses. That problem is that income, low parent-education families young children from economically and receive significantly less stimulation and socially disadvantaged families begin support than those growing up in families elementary school with knowledge and skill with higher parent-education and family levels that are substantially below those of income levels. According to the Head Start children from more advantaged families.

Whereas evidence suggests that local Head Start programs serve preschool EHS as currently children of ages 3 and 4, and 5-year-olds who have not yet started kindergarten, EHS constituted and serves infants and toddlers below the age of structured is less than 3.
