New data from the National Institute for Early Education Research reveal that 10 states took substantive steps to improve their pre-K programs between 2005 and 2007.  Five states achieved parity in pre-K and K-12 spending after not having done so previously; five states reduced their maximum pre-K class size to 20 students or fewer; and two states enacted requirements that pre-K teachers have a Bachelor’s degree.  Nevada and Pennsylvania achieved multiple policy victories, with both achieving parity in spending and reducing maximum class to 20.  Five states, meanwhile, weakened their preschool policy by removing requirements that pre-K teachers have a Bachelor’s degree. 

The table below provides details on those states that strengthened or weakened their preschool policy between 2005 and 2007.
