As online education's prevalence increases, postsecondary institutions have not met online learners' mental health needs. In-person learners benefit from accessible and robust campus services and activities to support well-being. However, many postsecondary institutions do not offer teletherapy or comparative social activities. Furthermore, online instructors have difficulty assessing student needs and referring them to the appropriate services. Several promising practices exist to address the disparity: postsecondary institutions can improve supports for online learners, and instructors can incorporate mental health and well-being resources and activities within curricula. While some evidence suggests the benefits of the solutions above, more research is needed.
