Oklahoma has the highest quality universal preschool system in the nation. Yet, the NAEP State Profile of Oklahoma shows once again that the state's huge investment in universal preschool is not improving student achievement in 4th grade reading. It is still lower now than before universal preschool was implemented; Oklahoma scores are below the national average; and UPK in Oklahoma has not closed the achievement gap between groups of students.
