Choose a forklift training program. There are many online training programs that provide OSHA certification upon completion, but these courses are designed specifically for experienced forklift operators who need new certification, not forklift beginners. Beginners need in-person training. Try the National Association of Heavy Equipment Training Schools (see Resources) for a list of programs.
Take the written exam. During the first part of your forklift training, you'll learn about parts of a forklift, OSHA standards, inspection rules and other basic guidelines. You'll be given a written exam on this material.
Take the operating exam. Once you learn the practicalities of operating a forklift, you'll actually get in and learn how to maneuver it. After the hands-on part of the training is complete, you'll be evaluated on your handling abilities.
Receive your certification. After you pass the written and operating exams, you'll receive a forklift operator's certificate. You'll need to show this to employers when applying for a forklift job.
