Clinical research associate (CRA)
In Roles & organizations
Also known as: monitor, clinical monitor
A clinical research associate monitors clinical trials on behalf of the sponsor or CRO. The CRA checks that each site follows the protocol, protects participants, and records accurate data, and writes up findings after every visit. Much of the work is now a mix of on-site and remote review.
Why it matters
CRA is one of the most in-demand roles in the industry. Most CRAs enter after some site or coordinating experience, which is why CRC is often the step before it.
Example
After a monitoring visit, the CRA writes a follow-up letter listing the findings \u2014 three missing source entries and one late SAE report \u2014 with the actions the site must take and by when.
Common questions
- What is the difference between a CRA and a CRC?
- A CRC works for the site and runs the trial there day to day. A CRA works for the sponsor or CRO and checks that the site is doing so correctly. They are counterparts, not seniority levels, and people move in both directions.
