IAT External Equivalency Frequently Asked Questions
One-Way NWCG S Course to A Course Equivalency Timeline
NWCG one-way S course to A course equivalencies have been granted within IAT for many years. Over time the IAT A courses that were granted as equivalencies have changed. This page lists a timeline of equivalencies from each Interagency Aviation Training Guide that has been published since 1999. The Interagency Aviation Sub-Committee has determined that any NWCG S course taken prior to 1999 will not be granted an A course equivalency. For quick reference you can view or print the IAT External Equivalency Quick Reference Document. Additionally we have created the IAT External Equivalency Guide to assist students with uploading certificates.
Please feel free to contact the IAT Admin with any other questions you may have.
