CITI Training Social and Behavioral Focus Practice Test

In international research, the age of majority is determined by the laws, customs, and norms of the country or area where the study takes place. Different places set different ages at which a person is legally able to consent to participate in research, and some contexts require parental or guardian consent, or a separate assent process, even for older minors. Because ethics and legality hinge on local context, investigators must follow the local jurisdiction’s requirements to protect participants and ensure compliant, respectful engagement with the community.

International treaties and general guidelines provide broad protections, but they do not override local age thresholds. Relying solely on the researcher’s home country laws or on institutional policies cannot substitute for the local legal and cultural consent requirements. In practice, researchers work with the local ethics committee or IRB to identify the applicable age of majority and the appropriate consent or assent procedures for the study site, ensuring alignment with both local law and international ethical standards.
