RETHINK: Planning and Designing for K-12 Next Generation Learning: iNACOL (the International Association of of K-12 Online Learning) and Next Generation Learning Challenges created this toolkit to help district, charter, and school leaders when they are just beginning to consider and design next-generation programs and schools, with personalized, competency-based, and blended learning. The toolkit includes links to many Opportunity Culture publications and tools, including some on staffing models, financial sustainability, and change management. Go here for our full list of Opportunity Culture’s school design tools, which we update often.
