Important Notice

MTAA Testing and Certification has been replaced by ATMT Testing and Certification at American Trainco, Inc.

MTAA no longer offers testing as part of its mission and has entrusted American Trainco with taking over that responsibility. Please contact  our testing administrator or your sales representatives for more information. If you have taken MTAA testing through American Trainco in the past your scores and results are transferrable for the purpose of receiving ATMT^® certification.
