This article visits the accountability of head start preschools that go beyond the scope of nap times and teaching nursery rhymes. President Obama often points to research showing a high quality pre-school program can lead to better academic performance through high school. But currently, these pre-k’s aren’t measuring up to standards to adequately prepare children. Currently, there’s not much of a measure for the knowledge learned in pre-k. But as states invest more heavily into pre-k educations, there are questions about how effective funding is in relation to the level of education of the children. As a result, numerous  programs are failing to prepare underprivileged pre-k students for elementary school. As a result, schools are reacting to this by revisiting the curriculum currently taught.
