Quick Tips & Best Practices

Authors/creators are strongly encouraged to make their work comply with accessibility standards.

  • When using images, either describe the image within the surrounding text, or use alt text. Read: How to Write Great alt Text—And why it Matters.
  • If an image is purely decorative and not necessary for comprehending the information, use " " in the alt text to let screen readers know they can skip the image.

  • Use contrasting colors rather than red/blue/green which all looks the same in black and white.

  • 12 point font should be used for most documents

  • 9 point font size is good for footnotes

  • Text should be able to be zoomed up to 200% on a website.

  • Make sure your text is in a logical reading order and don't skip heading levels (i.e. if your document/web page has Heading 4 it should also have Heading 1, Heading 2, and Heading 3). Screen readers skip from heading to heading in order.

Accessibility Resources

The accessibility of OER is an important factor to consider, especially in light of the online nature of most OER. Information about creating and evaluating the accessibility of OER is listed below:


Fundamentals of OER include DEIA goals and guiding principles. DEIA principles are baked into the philosophical movement of Open Access and Open Educational Resources and need to be confirmed and strengthened as we move forward.

Fundamentals of OA: diversity: increases diversity in content, form, and participants; equity: removes barriers for users and creators; inclusion: lifts up all voices, languages, regions, and points of view; accessibility: makes research and scholarship available and legible to all people regardless of disability or constraint.

Leveraging Open Educational Resources to Advance DEI: A guide for Campus Change Agents:

"[We support] the connection between OER and DEI through professional development that engages participants in topics such as accessibility assessment of instructional materials; localization and diversification of course content; involvement of students in content development and evaluation (i.e., open pedagogy); curriculum assessment for bias, inclusivity, and relevance to students; and implementation of culturally responsive pedagogy. These are topics at the core of both OER and DEI since both initiatives aim to create more equitable and inclusive learning experiences, deepen student learning, and close equity gaps for students from groups that are underserved by higher education. Campus units, such as centers for teaching and learning, that already have recognized training schedules and programs are key partners in this work.

Examples of tools used in professional development training in this domain include:

Making Ripples: A Guidebook to Challenge Status Quo in OER Creation: a short resource designed to expand your understanding of inequities in the educational systems through breaking down the work into smaller pieces with opportunities for you to reflect, identify strategies for action, and locate resources and community members to connect with. The purpose of this guide is to explore strategies for you as OER creators to incorporate equitable practices into your workflows.
