There is a challenge review at the end of each module. If you successfully complete the challenge review, you will be able to print a module proof of completion.

Students must be affiliated with an NWCG member agency (thru direct membership or agreement) or a member of a fire department to be issued a final NWCG certificate. After completing the CD version training required by your agency or department, a training officer or fire chief will evaluate required further training. The affiliated department can then certify students’ completion of the S-190 training by issuing the final NWCG certificate.
