Frequently Asked Questions

  • Annual Symposium
  • Do you have to be a member of the WSO to attend the WSO Symposium or to be a speaker?

    No, the WSO Symposiums are open to everyone wishing to attend or to participate as a speaker/presenter.

  • Certification
  • How long does it take to complete my certification?

    Once we have your application for certification, the two candidate evaluation forms, and a current resume/CV, we will process this package and send it to the WSO Certification Board for their evaluation. It takes two to three weeks to get the Board responses back in our office. If you are approved for a certification that does not require an exam, as soon as you pay the required fees your certificate will be forwarded to you. If you are approved for a certification that does require an exam, we will need to set up a date, time, and place for you to take the exam. How soon you take the exam is generally up to you. Once the exam is complete, the exam is graded and evaluated within two to three business days (Monday through Friday).

  • Do you have a study guide?

    Yes, we do! WSO offers three study guides: WSO Professional Level (WSO-CSE, -CSM, -CSSD, and -CSS); WSO Hazardous Materials (WSO-CHMT, -CHMS, and -CHME); and the WSO Entry Level. Please contact the WSO Membership and Certification Coordinator for more information or to order: 1-660-747-3132 or certification@worldsafety.org.

  • How long is the exam?
