Which condition must be met for research to be eligible for exemption under federal regulations?

For research to be eligible for exemption under federal regulations, it must meet specific categories outlined in those regulations. The federal guidelines define certain types of research activities that are considered to pose minimal risk to participants and, therefore, can qualify for exemption. These categories include, for example, research involving educational practices, surveys, or certain types of public service program evaluations where the risk to participants is minimal. Meeting these specific criteria allows researchers to bypass some of the more intensive regulatory requirements typically associated with human subjects research, facilitating the research process while still maintaining ethical standards.

The other conditions mentioned in the options do not align with the criteria for exemption. For instance, while informing participants about risks is essential in research ethics, it does not determine eligibility for exemption. The requirement for results to be unpublished does not apply to exempt research; in fact, many exempt studies can result in published findings. Lastly, research does not necessarily need at least one human subject to qualify for exemption; certain categories can pertain to entirely different subjects or data types that do not involve direct human interaction.
