One Stop Shop for Common Core State Standards, PARCC, Compass Resources, and Teacher Preparation Transformation "This web page has been developed to provide district and postsecondary personnel with quick access to national and Louisiana resources that can support their efforts to implement the Common Core State Standards, PARCC assessments, and Compass state teacher evaluation system. The concept for a “One Stop Shop” that requires only one or two clicks at a computer to reach CCSS, PARCC, and Compass resources was developed by members of Louisiana’s 2011-12 Blue Ribbon Commission for Educational Excellence. Educators on the Commission identified types of information that should be included and experts from across the State will help to identify well-developed cost-free resources to be added to the “One Stop Shop.”
