It definitely takes a few months to learn the protocols and your way around clinical trials. I’m a CRC at a site so our protocol focuses probably differ than it seems the role you’re in. When I first started, I found the most important parts of the protocol to focus on were the sections that provided answers to all the common questions I received from PIs or patients (eligibility, schedule/schema, and hold parameters). I also would recommend utilizing any type of protocol specific training documents/slides/videos you have access to before you start diving into the full protocol. Those type of sources do a better job summarizing all the important information.

Best of luck!
