Remove arbitrary seat time rules and focus on content mastery
Most education systems are organized around specific requirements related to the number of hours (or even minutes) a student receives in a day, week, and schoolyear. These requirements usually influence funding, staffing, schedules, how content is delivered, and other core areas that serve as an obstacle to innovative approaches.
States would be wise to transition from these arbitrary requirements that have little correlation to learning. Instead, focus on master of concepts and skills, regardless of time, place, and pace. This effort will likely require states, districts, and schools to rethink traditional school practices like grouping children by age, organizing content by grade-level and subject area, and funding based on time.
