Levels of MPT Certification

Certification for MPT technichians is divided into three levels, each presenting preventing exempliing scope of responsibility, knowdge, and authority. The specific requirements for each level vary slightly between standards, but thee general structure is universally requarzed.

The Level I typically follows written procedures provided the higher-level technical and is nott authorized to interprets individently or make acception / reject desidents.
