All resources used and work performed must fall strictly under the scope of employment with your organization or institution. If you indicate that you will accomplish your research outside the scope of your employment or affiliation with an organization or institution (e.g., “None” or “N/A”), you will be asked to describe the non-organizational/institutional resources and specify the appropriate data safeguards to be employed in pursuit of your research plan.
