There is not a place that specifically shows the before and after of what was updated in a course aside from the generalities like DSM-V updates. For courses going through review, a couple of things occur. We check that all the references are up-to-date and recent. (Many accrediting bodies require sources published within the last 5 years.) Additionally, we also check regulations to ensure that the course references the most recent version of regulations. All courses going through updates are checked for relevance, accuracy, and current material.
