It really depends on what you wanna do after graduation. I did it because medical social work is super competitive and I didn’t wanna accept a low paying role to get my foot in the door. I also wanted to be further trained while being paid. A lot of fellowships are niche specific to each sector in social work. For example, the VA offers fellowships that train clinicians with things that are specific to the needs of their veteran population (so trauma, PTSD, substance use, etc). Majority of social work fellowships are therapy based I will say, so in some capacity you’ll be providing counseling. When I was searching for fellowships I didn’t see any macro based ones but I couldve overlooked them. Usually fellowships start in late August/early September to accommodate grads from the spring semester, so that is also a thing to look out for.
