The effort to get a snapshot of kindergarten readiness is part of the National Survey of Children's Health, which collected information from thousands of parents and guardians about their child in five areas - early learning, motor skills, social-emotional development, self-regulation and health. The goal was to answer an overall question: Is your child ready for school? Readiness in California is on par with the nation's average, which also puts kindergarten readiness at two-thirds of 3- to 5-year-olds.
