Accessibility Assessment
Below is a short accessibility assessment of key areas that have been assessed during the production process of this open text. The checklist has been drawn from the BCcampus Open Education Accessibility Toolkit. While a checklist such as this is just one part of a holistic approach to accessibility, it is one way to begin our work on embedding good accessibility practices in the books we support.
We hope that by being transparent on our current books, we can begin the process of making sure accessibility is top of mind for all authors, adopters, students and contributors of all kinds on all our open-text projects. As such, we welcome any feedback from students, instructors or others who encounter the book and identify an issue that needs resolving.
