COOL (Credentialing Opportunities On-Line) helps Marine Corps Service members find information on certifications and licenses related to their jobs. Use COOL to get background information on credentialing and find detailed information on:

  • Credentials related to a Marine Corps Military Occupational Specialty (MOS)
  • Credential requirements and potential gaps between Marine Corps training and civilian workforce credentialing requirements
  • Resources available to fill gaps between military training and civilian credentialing requirements
  • How to get a COOL funded voucher to pay for credential exam and maintenance fees

Spend a little time getting acquainted with COOL and credentialing using the Main Menu at the top of the page, and then dive into your occupation-specific information using the Go to: or Navigator options at the top-right of every page.
