In my first post on the topic of realizing the promise of open educational resources, I described the IM Certified program. Our partners offer multiple versions, including a free online version and enhanced versions with different options for users. This is IM’s way of reaching teachers and students from a wide variety of districts who may be looking for those different options, while assuring that, as these versions evolve, they will stay true to the original design. However, by the terms of the CC BY license, anybody can use the curriculum with or without certification. This freedom further supports our mission to get these carefully crafted materials into the hands of as many students and teachers as possible.
