Quick Reference: NAICS

Picking the right NAICS code determines small business size standards and which set-asides apply. The SBA publishes the official table of size standards by code.

  • Pick the code that matches the work you actually perform
  • List multiple codes if you have distinct service lines
  • Check size standards before claiming small business status

Quick Reference: Acronyms

Federal contracting is acronym-heavy. A few of the ones you will see most often:

  • SAM — System for Award Management (registration)
  • NAICS — North American Industry Classification System
  • CO / KO — Contracting Officer
  • COR / KTR — Contracting Officer Representative
  • CPARS — Contractor Performance Assessment Reporting System
  • IDIQ — Indefinite Delivery / Indefinite Quantity
  • FAR / DFARS — Federal Acquisition Regulation / Defense supplement
  • CMMC — Cybersecurity Maturity Model Certification
  • CUI / FCI — Controlled Unclassified Information / Federal Contract Information

How contractors use these tools

  • Build a defensible cost basis before submitting a price proposal
  • Track win rate by count and value to spot capture process problems
  • Confirm small business status before bidding a set-aside
  • Estimate the full multi-year value of an IDIQ or option-laden contract
