Like House Bill No. 15, this Act permits early childhood educators in the public schools to use and encourage play-based learning in their classrooms and in their curriculum. This Act permits local education agencies to provide early childhood professional development in play-based learning, which may include professional development programs developed by the Department of Education. This Act also permits the Department to promulgate regulations for purposes of implementing this Act. This House Substitute No. 1 for House Bill No. 15 incorporates the changes from House Amendment 1 to House Bill No. 15 with respect to the definitions of early childhood education and early childhood educators encompassing education from prekindergarten through second grade, adding topics that may be included in materials developed to provide ongoing early childhood professional development in play-based learning, and making technical corrections for clarity. This House Substitute also updates the definition of “play” and “play-based learning” contained in House Bill No. 15 and adds a definition for “guided play”.
