To access the data, start by creating an NDA account or login to your existing one. After login, go to your account’s Data Permissions dashboard. Here you can request or renew access electronically to one or many repositories in NDA, including CCF and others.

In the Actions column in the ABCD/CCF Permissions group row, select “Request Access” and complete the access request instructions to create a signed Data Use Certification (DUC). There are three criteria you must meet to be eligible to request NDA access:

  1. You must have a research-related need to access the data

  1. You must be associated with an NIH-recognized research institution, defined as an institution registered in the NIH electronic research administration system (eRA Commons,) and have the approval of an authorized signatory official of that institution.

  1. Your institution must have an active Federalwide Assurance (FWA).

If you have questions, please view NDA's tutorials or email NDAHelp. Once approved, access is valid for one full year, at which point a renewal request should be submitted through the same process as above to maintain access.
