Step #1 in the Oklahoma Green Schools Program is to register your school. Registration includes both the National PLT website and the O.G.S.P website. When you register your school, you will be asked how your school can best implement the OK Green Schools Program. Every school is different, so the O.G.S.P may look different from school to school. However, several models are already being implemented across the State. Find the strategy that works best for you. National PLT provides the 5 school investigations that you and your students can explore. These 5 investigations are available for download at PLT.org. Then register your school at OKGreenSchools.org. Welcome to the Oklahoma Green Schools Program.
