Several years ago, in the face of these rising costs, CVTC realized it was time for us to make learning more affordable and accessible, and we continue on that journey. Since 2013, CVTC has been a leader in the development of open education resources (OER). Our OER teaching and learning materials are licensed to be used, shared, adapted, and retained at no charge and do not require extra permission. Like OER, affordable educational resources (AER) make use of resources such as eBooks or journal articles that cannot be shared, adapted or retained but may be used at no cost to the student.
