All Capstone participants require a TS/SCI with SI, TK, G and H accesses.

Clearances have to be fully adjudicated, not interim.

  • All Clearance/Accesses must be up to date and posted in the Defense Information Security System (DISS) 30 days prior to the start of your Capstone session. NDU uses DISS ONLY to verify both Top Secret clearance and SCI access.

If your Top Secret clearance and SCI accesses are posted in DISS there is no further action necessary – we will confirm your clearance via JPAS. 

If your clearance is not posted in DISS your agency Security Officer and agency Special Security Officer (SSO) will need to pass clearances separately. The preferred method is submission of a visit request by fax on agency letterhead to 202-685-3765. The fax must include: date and place of birth, clearance date, investigation type, and investigation date. Purpose must include CAPSTONE. POC: Bonnie Swanson.  

**NDU Security does not have access to Scattered Castles for clearance / SCI verification.**

  • Fellows must have a current Top Secret clearance with SCI eligibility. All Fellows must have a current Top Secret clearance with SCI eligibility based on a current Single Scope Background Investigation (SSBI), Special Background Investigation (SBI), SBPR (Periodic Reinvestigation), or agency equivalent.
  • Fellows must be eligible for SCI access on DAY ONE of the course. Those Fellows not currently read in (indoctrinated) to SCI accesses should be briefed (indoctrinated) at least 30 days before attending the course.  NDU can not indoctrinate you. 
  • Required Compartments. The compartments required for Capstone participation are SI, TK, Gamma, and HCS. Contact your agency SSO to ensure you meet Capstone compliance.
