What are the highest level of college degrees in order of the lowest to the highest?

The highest level of college degrees, in order from lowest to highest, typically starts with an associate degree, followed by a bachelor's degree, then a master's degree, and finally a doctoral degree (Ph.D. or equivalent). Some fields may also include professional degrees, such as a J.D. for law or M.D. for medicine, which can be considered on par with or above a doctoral degree depending on the context.
