You need to complete an online training module and pass a test before being legally allowed to conduct psychology research. Below is a copy from a webpage from the OSU Research Office:
Training in the Ethical Use of Humans in Research
The research community has a responsibility to ensure that the treatment of human subjects in research meets the highest ethical standard. Recognizing this responsibility, the National Institutes of Health (NIH) requires NIH funding recipients to certify training in the ethical use of humans in research. Endorsing the goals of such training, the OSU Institutional Review Board (IRB) requires education in the protection of human research participants for all researchers conducting research involving human subjects, not just those receiving NIH funding.
The online training module for this certification can take anywhere from 1 to 4 hours to complete. You will receive a copy of your certification after you complete it (please keep these for your records). Please pay attention that you are doing the human subjects module and not animals and make sure you pay attention to each section, as there will be quizzes at the end of each part.

Note that you must pass the test for each required module with a score of 80% or better. Once a passing score is obtained for all required modules, the CITI system automatically generates a certificate of completion and forwards it to the OSU IRB. No further documentation of completed education is required from OSU study team members.
