The "2021-2022 Louisiana High School Planning Guidebook" consolidates the policies and programs that are most relevant to high school educators as they plan for the upcoming academic year and prepare every student for college and career success. Ensuring every high school student is on track for success is but one of the educational priorities for the Louisiana Department of Education. Other priorities include: (1) ensure every student is on track to a professional career, college degree or service; (2) remove barriers and create equitable, inclusive learning experiences for all children; (3) provide the highest quality teaching and learning environment; (4) develop and retain a diverse, highly effective educator workforce; and (5) cultivate high-impact systems, structures and partnerships. The high school experience opens doors for young adults--sparking interests, presenting opportunities, and expanding possibilities. To maximize this experience, students must have a smooth, well-planned transition to high school; to ensure their success until graduation, all students must have access to a range of academic opportunities and behavioral supports.
