Pre-K Programs Pay Off

Oklahoma enjoys a popular image as a state of wildcatters, hardscrabble farmers and rodeo riders. So it might come as something of a surprise to learn that national organizations rate the state as tops in the USA in — preschool.

Oklahoma offers "universal" preschool, which means that parents of all incomes have the option of sending their 4-year-olds to a state-sponsored preschool, transportation included. The state also insists that all preschool teachers hold bachelor's degrees, and they are paid the same as regular school teachers.

States have good reasons to aspire to universal preschool, especially high-quality programs with good teachers and low student-to-teacher ratios. Universal preschool can help fill a void: Poor families have access to Head Start. Well-to-do families pay for quality preschools out of their pockets. In between are lower-middle class families whose children badly need the readiness skills that preschool provides.

Oklahoma educators credit their decade-old preschool program with pushing up reading and math scores in the lower grades, and with raising achievement by low-income children.

Elite preschools — such as the experimental Perry Preschool in Michigan, where researchers followed the poor and minority children who attended that school well into adulthood — return more than $16 to society (in the form of lower crime and higher employment) for every dollar invested, according to the non-profit High/Scope Educational Research Foundation. Even decent-quality preschools produce gains in the $4 to $10 range, other researchers found.

States pay a price, however, for pushing too fast for universal systems.

Florida rushed its preschool system out the door with seemingly little attention to setting standards. Florida cosmetologists face stiffer licensing than preschool teachers, and preschool operators there are free to pursue a choose-your-own-curriculum policy.

Making Florida's preschool program more worrisome is the low funding. Among the 38 states that underwrite preschool, Florida ranks 35th. Universal preschool is a great idea that can turn bad when implementation outstrips the money.

Preschool classrooms with too many children and too few teachers have surprisingly high expulsion rates, researchers reported earlier this month. The ratio in preschools shouldn't rise above 10 students for each teacher, they recommended.
