The Shopify Partner Academy is the closest thing we would have to something like this. It has an exclusive collection of courses, study guides, and exams help you develop critical commerce skills, test your knowledge, and get started on the right foot as a Shopify Partner. Just to note, to work in the Partner Academy you must be a Shopify Partner also.
