Technician A says ASE certification is mandatory in all 50 states before performing an automotive repair for pay. Technician B says automotive training programs must be reviewed every 3 years to be recertified. Who is correct?

Technicians A is  correct

Explanation:

According to ASE ( Automotive service excellence) "Certification credentials are valid for five years. If it has been five years or more since you took a test, it’s time to register for the corresponding Recertification Test. The five-year requirement ensures certified professionals are current in this rapidly changing industry."

This counters the claim of technician B who say the programs must be reviewed every three years  , and ASE sends you reminders before your credentials expire.
