The Department of Education and Early Development (DEED), in partnership with the Department of Health and Social Services (DHSS), developed this guidance document to support planning and strategies for reopening schools. Alaska's 'Smart Start 2020' framework for K-12 schools provides a tiered approach based on COVID-19 pandemic risk levels per community. School districts and communities will work together to develop clear, actionable steps that are necessary for teaching and learning to continue throughout the 2020-2021 school year. These health parameters provide a basis for plans that are specific, actionable, and broad enough to be adaptable. Alaska's Smart Start 2020 is built upon the guidance and recommendations of health officials and collaborative conversations with education stakeholders; it is aligned to the reopening guidelines that have been provided by Alaska's state and federal leaders; and it is designed to help districts prioritize the health and safety of students and teachers as they deliver instruction for the 2020-2021 school year. Updated guidance in this revision includes: (1) Clarified how green, yellow, and red operational zones differ from DHSS long-term care facilities alert levels; (2) Added general principles box, guiding principles box, and specific definitions; (3) Added specific outbreak, isolation, and quarantine guidance; (4) Clarified how travel mandate applies to schools; (5) Added cohorting guidance; (6) Attached examples of forms and educational materials for students and parents; (7) Attached checklist for health and safety considerations for district plans; and (8) Added new CDC guidance and Council of State and Territorial Epidemiologists (CSTE) outbreak definitions.
