Rigger and Signal Person Certification

The Rigger and Signal Person Certification is a free intermediate-level, 20-minute skill test from Science of Apps. It tests rigging and crane signaling for construction and industrial workers — rigging fundamentals (sling types, hitches, load weight and centre of gravity), hardware and inspection (shackles, hooks, eyebolts and removal-from-service criteria), signaling (standard hand signals, voice/radio and stop authority), and safety and regulations (sling angle effects, exclusion zones and OSHA/ASME requirements). Written to OSHA Subpart CC (1926.1400), ASME B30 and NCCCO references for 2026. It covers principles; hands-on, accredited certification is still required to rig or signal on the job. Score 70% or more on its 20 questions to earn a verifiable Rigging and Signaling Proficiency certificate (SOA-RSP). Every question is based on published standards and research — including ASME B30.9 Slings and B30.26 Rigging Hardware (ASME), NCCCO Signalperson certification program (National Commission for the Certification of Crane Operators), 29 CFR 1926 Subpart CC Cranes and derricks in construction (rigger qualification) (OSHA) — and each answer is explained with its source.

Science of Apps offers a free Rigger and Signal Person Certification, updated for 2026 and 2027. It measures rigging fundamentals, hardware and inspection, signaling and safety and regulations and gives instant results with a shareable certificate.

Read the four skill areas on this page, then take the 20-minute test online — no fee, course or sign-up. You see every answer explained when you finish. Score 70% or more and you get a Rigging and Signaling Proficiency certificate straight away, on screen, as a PDF and by email, with a credential ID anyone can verify.

Yes. The questions are original scenarios written by Science of Apps, and each one is based on a public source you can read: ASME B30.9 Slings and B30.26 Rigging Hardware (ASME); NCCCO Signalperson certification program (National Commission for the Certification of Crane Operators); 29 CFR 1926 Subpart CC Cranes and derricks in construction (rigger qualification) (OSHA); NCCCO Rigger Level I and II certification (NCCCO). The source is shown under each question and linked in the answer review. Science of Apps doesn't copy questions from other tests.

Four skill areas with five questions each, drawn from a bank of 10 per area so a retake brings new questions: Rigging Fundamentals (Slings, Loads and CoG); Hardware and Inspection (Shackles, Hooks and Inspection); Signaling (HandSignals, Voice and Authority); Safety and Regulations (SlingAngle, Zones and Rules). Every question is an original scenario written to the 2026–2027 standard, with the published source named under it.

Rigger or signal person, Crane or construction crew member, Industrial maintenance worker, Site supervisor or safety officer and Trainee preparing for accredited certification. It suits anyone who wants a quick, verifiable way to show Rigger Signal Person knowledge in 2026 and 2027, from students and career switchers to experienced professionals.

Signals must come from a qualified signal person (or the operator's own view), and everyone must use a standard signaling method agreed in advance — usually hand signals or radio. However, a stop signal from anyone must always be obeyed, because stopping is a safety action available to all workers.

As the angle between a sling leg and the horizontal decreases, the tension in each sling leg increases for the same load. A low, flat angle can multiply the force far beyond the load's weight and overload the sling, so riggers use load-angle factors and keep angles as steep as practical.

Yes. The test is online, in English and free everywhere — people take it from India, the US, the UK, Europe, Africa, Latin America and Asia-Pacific. Your certificate is dated with your own local date and can be verified from anywhere at scienceofapps.com/certification/verify/.

20 questions — 5 from each of 4 skill areas — with a 20-minute limit. You need 70% (14 of 20) to pass and 90% for distinction.

We rate it Intermediate: assumes hands-on experience in the role. It has 20 scenario questions — 5 from each of 4 skill areas — and a 20-minute limit. You need 70% (14 of 20) to pass and 90% for distinction.

Nothing. There is no fee to take a test, to receive the certificate, to have it emailed or to verify it, and no sign-up.

On our server, not in your browser. The answers never reach the page until you submit, so a certificate can only be earned by passing. Each certificate gets a unique credential ID stored by Science of Apps.

You see your score for each area and every question with the correct answer and why, with the published source behind it. You can retake after 30 minutes, and the retake draws questions you haven't seen yet.

No. Every certificate is dated, so it always shows when you passed. Retake a test any time for a newer date or a higher score.

Yes. After you pass, Add to LinkedIn opens the Licenses & certifications form with the certificate name, Science of Apps as the issuer, the issue date, your credential ID and the verification link filled in. You can also download it as a PDF or PNG, and it's emailed to you as a PDF.

Every certificate has a credential ID and a QR code. Scanning it, or entering the ID at scienceofapps.com/certification/verify/, shows the holder's name, the certification, the score and the issue date from our records.

No. They are Science of Apps' own assessments of applied skill. They aren't issued by a university or standards body, and they work best alongside a portfolio that shows the skills in real work.
