This question focuses on the scope of work you will be performing. Regardless of what an agreement is called, it is the scope of work and details of the parties’ relationship that will determine appropriate departmental routing; faster triage will reduce delays in institutional review and approval.
For example, many agreements are labeled as a Material Transfer Agreement (MTA) and thus routed internally as an MTA, but must be re-routed to another department or re-negotiated as a research collaboration agreement upon CU AMC determination that the investigator will be collaborating on publication and analysis and would like some of the details of this relationship detailed in the contract.
