In the old days, DCMA stayed away from classified contracts - they checked the out-of-SCIF files for compliance documentation but didn't beat you up too much if the evaluative documentation was cloudy and seemingly incomplete. But those are the old day. These days, your CPSR Data Call will ask you for the dollar value and percentage of classified prime and subcontracts as well as your purchasing system percentage output under those contracts. If it's substantial, you may get a follow-up requesting the clearance level of each prime contract.
