does anybody know of a source for complete information about specialty and sub specialty pathways?

I am looking for a flowchart/infograph or a sufficiently complete list to complete one.

For example: if I want to be a pediatric oncologist what training do I need or if I want to be a critical care intensivist what residencies could I start with. I am looking for information that answers this type of question but broadly for all current specialty pathways.

The more I look into subspecialties the more niche options I find and I feel I/all of SDN would benefit from making or locating such a flowchart/infograph.

PS: I've done the googling and have not found a source I am sufficiently confident in yet so please don't be an asshat about searching before posting. Thanks.

Purchase Iserson's Guide to Residency. It lists most, if not all, of the professions and the type/amount of medical training needed for each. Its not a flowchart, but its something.

I second this. Iserson also has a premed guide which is even accurate up 'til today.

Check the board websites? They list which residencies are eligible for what fellowships/certifications.

You could try using FREIDA. They recently changed it so that now you have to sign up for an online account to browse but I don't think that's a big deal.

You can use it to browse all existing residencies and fellowships. For fellowships I think you can see what residency training they will accept as well.

It was built to search available programs so if you want to explore, for example, cardiothoracic surgery residencies in Illinois, it will list all of them along with details like pay, average hours per week, etc.

Here is a copy and paste of the entire list of residency/fellowship types from FREIDA. All the listings with (parentheses) are fellowships. The letters inside the parenthesese indicate which residency the fellowship is available after. For instance, Sports Medicine (FM) is a sports medicine fellowship available after a family medicine residency while Sports Medicine (EM) is a sports medicine fellowhsip avaialble to emergency medicine residents.

Just this list won't give you a perfect understanding as many fields do require an intern year before you start, but I'd say if something from the list sounds interesting, google it.
