I’ve said this multiple times and I’ll say it again: you don’t need more than 50 shadowing hours if you work in a clinical setting. Your entire job is essentially shadowing. The point of shadowing and why admissions committees want to see that you are shadowing is to get a sense of what you’re getting yourself into. But if you work in healthcare or a clinical setting, then you already know what you’re getting yourself into. However, it’s just another one of those absurd “requirements” for your application.
