The mission of the International Association for K-12 Online Learning (iNACOL) is to ensure all students have access to world-class education and quality online learning opportunities that prepare them for a lifetime of success. "National Standards for Quality Online Courses" is designed to provide states, districts, online programs, and other organizations with a set of quality guidelines for online course content, instructional design, technology, student assessment, and course management. The original initiative in version one of the standards began with a thorough literature review of existing online course quality standards, followed by a survey offered to representatives of the iNACOL network to ensure the efficacy of the standards adopted. As a result of the research review, iNACOL had chosen to fully endorse the work of the Southern Regional Education Board (SREB) "Quality Online Course Standards" as a comprehensive set of criteria. The standards as identified by SREB, already in use by 16 SREB states, proved to be the most comprehensive and included guidelines set forth in the other criteria from the literature review. Since the original standards were released, other organizations have released quality standards for online courses. iNACOL organized a team of experts in the area of course development, instructional design, professional development, research, education, and administration to review these new standards and new literature around the topic and determined there was a need to refresh version one of the iNACOL standards. In this new version of the standards, reviewer considerations have been added for each indicator. Additionally, a rubric has been included to assist in the review of online courses based on this new version. (Contains 2 footnotes.)
