I’ve been teaching a course through LinkedIn Learning since 2015 focused on teaching accessibility in WordPress. The course is currently in its 3rd edition, released on June 9th, 2023. This version of the course includes almost 3 hours of material covering a wide range of topics.
The course provides introductory materials about the principles of accessibility, the legal framework for accessibility internationally, and explanations of assistive technology and how it works.
The course goes further in depth on how to write and create content that’s accessible in WordPress, how to test themes and plugins to identify accessibility gaps, and talks about what kinds of concerns you need to think about when picking the plugins that will power your site.
I also give a wide variety of development tips for people creating themes or writing plugins, so that the whole WordPress ecosystem can be improved from the ground up.
