It describes an open access course as one where students can enroll formally, paying fees to receive support and qualifications, or informally, having full access to course content and events without assessment or certification. The document also presents preliminary findings from a case study of an open access course at Otago Polytechnic, noting mixed financial results but benefits like improved completion rates, flexibility, community building, and opportunities for learners to try the course before enrolling.
