FAQ
Common Questions
Which industry certifications are most in demand by employers?
NCCER Instrumentation Technician
Do I need an associate degree, or is a certificate enough?
NCCER programs qualify you for contractor helper/entry roles immediately. A two year Associate of Applied Science (AAS) in Industrial Instrumentation may accelerate advancement into direct plant maintenance and controls roles.
What other prerequisites are required?
- Safety Council Orientation Badge
- Valid Driver’s License
- TWIC Card
Do I have to pass a drug screen and background check?
Yes. Industrial plants, chemical facilities, and refineries maintain strict zero-tolerance policies. You will be required to pass pre-employment and random screenings and clear a background check.
What is a TWIC card, and do I need one?
A Transportation Worker Identification Credential (TWIC) issued by TSA is mandatory for unescorted access to maritime and petrochemical facilities along the Mississippi River, Gulf Coast, and Louisiana ports.
Can I enter this trade with a prior record?
Certain felony convictions disqualify candidates from obtaining a TWIC or plant security badge (especially related to violence, weapons, or industrial sabotage). Non-violent or older infractions may be reviewed case-by-case through an appeal or waiver process.
Is a valid driver’s license required?
Yes. Almost all contractors and plant facilities require a valid driver’s license to drive inside operating plant boundaries and access remote sites.
