A "waiver of consent" in research refers to a situation where an Institutional Review Board (IRB) grants permission for a study to be conducted without formally obtaining consent from participants, but only under specific conditions. This usually occurs in studies where obtaining consent is impractical or poses risks to participants that outweigh the benefits of obtaining it.

The IRB must consider several criteria before granting a waiver. These include situations where the research involves minimal risk to participants, the rights and welfare of participants are not adversely affected, and it is impracticable to obtain consent. Examples might include studies utilizing existing data where individual consent cannot be feasibly obtained, or in certain types of public benefit research.

In contrast, other options do not accurately capture the essence of a waiver of consent. For instance, giving participants the option to opt out relates to informed consent rather than a waiver. Verbal consent contrasts with the requirement of a waiver because it still implies that consent is sought. Also, informing participants after the study contradicts ethical guidelines that emphasize participant autonomy and the necessity of obtaining informed consent prior to participation.
