I honestly wouldn't spend any money on training or education until you secure a position as a research coordinator. This job is so variable depending on your practice location. This course may provide you with some info regarding fed regulations, GCP and the way some positions are set up however until you are in this job it is hard to grasp what a CRC does. If you want some free training in the history of research and GCP take the course at citiprogram.org. The NIH also has some training online.
