according to subpart d, research with children may be eligible for exemption under category 2

According to Subpart D of the Federal Policy for the Protection of Human Subjects, research with children may be eligible for exemption under Category 2 only when the research involves the use of educational tests. Other research activities such as interviews, surveys, or participant observation with researcher interaction involving children are generally not exempt under Category 2. Additionally, observations of public behavior may be exempt only if the investigator does not participate in the activities being observed. The exemption also hinges on whether the information obtained is recorded in a way that human subjects can be identified and whether disclosure could place subjects at risk of harm.
