Answer:
When the research involves the use of educational tests
Step-by-step explanation:
The Common Rule defines practices which meet with human subjects the concept of research and are therefore not subject to the provisions of the rule.
Subpart D prohibits any use of children's exemptions as subject matter.
The types of exemptions which can be used with children include:
- Studies conducted in educational settings developed or generally accepted, involving standard educational procedures
- Research about educational tests.
- Observations of children in public environments, ensuring that the researcher does not engage in the observed events.
