A researcher asks an IRB to waive the requirement for parental permission for a study conducted in schools because the nature of the research requires participation of all the children present in classrooms on the day the research will take place. Assuming that the basic research design could be approved by the IRB and the school, which of the following requirements must be met before an IRB could waive parental permission?The research must pose no more than minimal risk. An independent consultant must approve the waiver. Parents must be notified that the study is taking place. The students must be offered an optional classroom activity.

The research must pose no more than minimal risk.

Explanation:

In research, minimal risk refers to the type of risk that only expose the subjects with very little level of discomfort. Typically, this type of risk is required for test subjects who haven't entered adulthood.

Children specifically, still haven't experience perfect development in both of their physiques and brain capacity. This make them became extremely vulnerable for scientific experiments. One single mistake could destroy the rest of their life.

This is why before the researchers even think about asking permission to their parents, they need to ensure that every procedures in the research only  pose no more than minimal risk.
