Primes have different requirements, also depending on geographical areas. Please visit the Primes matrix. Although they tend not to be NADCAP accreditated themselves, they are now asking their suppliers to seek NADCAP approvals. Securing the Prime's support is key to successful application and future business collaboration.
Some NWAA members are NADCAP approved. You may find it useful to speak to them and share their experience. See current list.
The NADCAP accreditation body is US Performance Review Institute. Application is done online. The UK is their European platform. Assessors/Auditors are actively sought worldwide, particularly those with linguistic skills.
The NADCAP process is described here.
