OSHA 10 or 30-hour safety certification - Construction and industrial safety. Cost: $50-$200. Time: 10 or 30 hours online. Value: Required by many employers, demonstrates safety knowledge.

Medium priority (if it fits your path):

Welding certifications - Helpful for all mechanical trades. Take courses at community college using GI Bill. Cost: $0 with GI Bill. Value: Increases versatility and employability.

Low priority (nice to have):

CDL (Commercial Driver's License) - Helpful for mobile mechanics or fleet work. Cost: $3,000-$7,000. Value: Increases job options, sometimes required.

Manufacturer-specific certifications - Often provided by employers after hiring (Caterpillar, Cummins, Carrier, Trane, etc.). Value: Specialized knowledge for specific equipment.
