Earlier this month I posted a proposal for an Introduction to WordPress Development syllabus and asked the community for feedback.
A note on naming. When I shared the proposal post, I used the term learning path to describe the list of topics being gathered. During the feedback process, I realized that this name was incorrect and that what I was proposing is in fact better described as a syllabus (from the Late Latin syllabus meaning “list”) of topics that should be covered at the beginner level. I have therefore adjusted the name of the list for this post.
Thanks to all the great feedback on the contents of this proposed syllabus, I am able to update this list to include all the topics relevant to the beginner WordPress developer. At the same time, I have linked any existing Learn WordPress tutorials I am aware of, or any tutorials that are in progress, that fulfill specific items in this list.
Tutorials still in progress are included after the topic as indicated by (WIP).
