OSHA 10 and OSHA 30 are courses, not exams — here is what that means for you
The two credentials in this section are the most misunderstood on the site, so this page starts with the correction. OSHA 10 and OSHA 30 are completion cards from the OSHA Outreach Training Program: a voluntary program of safety courses for workers and supervisors — the hours are in the names — taught by trainers whom OSHA authorises after they complete the OSHA #500 trainer course. OSHA does not require a test to earn the card, publishes no passing score, and does not itself set or fund the card fee — each Authorizing Training Organization sets its own. Any quiz you take is at the trainer's discretion.
That matters for how you use these pages. The practice questions here review the course content — hazard recognition, fall protection, electrical, struck-by and caught-between hazards, personal protective equipment, workers' rights — so that the hours you spend in class stick and so that you can answer the employer or site that asks what you learned. They are not preparation for an official exam, because there is none.
What is regulated is who may teach. Classroom courses must be delivered by an OSHA-authorised trainer; online courses may be delivered only by OSHA-authorised online providers, and OSHA itself runs none. Cards are issued by the trainer's Authorizing Training Organization within a set period after the class ends. OSHA 30 is aimed at supervisors and workers with safety responsibility; trainers who teach it must themselves have years of construction safety experience.
Which course applies
Links go to the course guide, where the topics, hours and card process come from OSHA's program documents.
OSHA 10 is an orientation to workplace hazards and workers' rights. Take it from an OSHA-authorised trainer or an OSHA-authorised online provider; the card follows completion, not a test.
OSHA 30 goes deeper into hazard management. Aimed at supervisors, foremen and safety leads; some states and owners require it for those roles.
Several states and cities mandate the cards for public construction or for all construction workers. The requirement is the state's, and it specifies which card and whether online delivery counts.
Only OSHA-authorised online Outreach providers may deliver the course online. OSHA lists them; a provider not on the list cannot issue a valid card.
How the card is earned
- 01Pick the card that matches your role: OSHA 10 for an entry-level worker, OSHA 30 for anyone supervising or carrying safety responsibility, in the construction or general-industry version your site works under.
- 02Enrol with an OSHA-authorised trainer for a classroom course or an OSHA-authorised online provider; confirm the provider appears on OSHA's list.
- 03Complete the hours. There is no OSHA exam; a trainer may quiz, and the class itself is the requirement.
- 04Receive the card from the trainer's Authorizing Training Organization within the period OSHA sets after the class ends.
