The document discusses opening up educational assessments by making them shareable and embeddable like open educational resources (OERs). It describes how some organizations have begun embedding formative assessments in online courses. The authors propose a proof-of-concept system called OpenAssessments.org that would allow assessments to be embedded in any web content using an application programming interface. Their goal is to advance open assessment practices and help educators evaluate students without reinventing exam questions for every course.
