Government contractor labor categories
Each labor category below is a role defense contractors bill the government under, defined by years of experience, education, and scope. Every page lists the experience levels (I through IV), GSA CALC+ ceiling rates, estimated salary ranges, the share of roles that require a clearance, the military codes that map to it, sample resume bullets, and a free level calculator. Everything is built for transitioning service members and federal employees moving into GovCon.
