We spoke several weeks ago about the need to get IRB Approval for certain primary research practices. I want you to look up "IRB Approval" both on our NMT site and by doing a Google search. From what you read, tell me first what an "IRB Approval" is. Second, why is IRB approval important to secure and for what kinds of projects it is critical? Based on what you've read, why does your project need to have it or why does your project not need to have it?
