A child's developmental progress is as unique as their personality or physical appearance. Early development is shaped by genetic make-up, neonatal influences, and day to day interactions with caregivers from birth. Head Start uses research-based assessment tools to measure child development and help parents understand how to boost their children's physical, emotional, social and cognitive growth. Tools that measure child development can yield numbers -- data -- but the data must be translated into the language of child development. This report provides data and stories of children's developmental progress in Minnesota Head Start. (author abstract)
