100+ Free STSC Practice Questions

The Safety Trained Supervisor Construction (STSC) is a BCSP certification for construction supervisors. Unlike the broader STS, the STSC focuses specifically on 29 CFR 1926 construction standards, the Fatal Four hazards, and leadership responsibilities on a construction site. It is administered by Pearson VUE at worldwide test centers.

STS (Safety Trained Supervisor) is a general supervisor credential covering any industry - general industry, manufacturing, oil and gas, etc. - and references 29 CFR 1910. STSC (Safety Trained Supervisor Construction) is construction-specific and built entirely around 29 CFR 1926 construction standards, with heavy emphasis on fall protection, scaffolds, excavations, cranes, steel erection, and silica. If you supervise construction workers, choose STSC; if you supervise in general industry, choose STS.

Candidates need 30 hours of safety, health, and environmental training PLUS one of: (1) 2 years of supervisory experience in construction, (2) 4 years of construction work at minimum 18 hours per week, (3) an associate degree or higher in occupational safety, risk management, or construction management, or (4) completion of a 2-year trade/union apprenticeship program.

The application fee is approximately $160 and the exam fee is approximately $160, for a combined initial cost of around $320. Recertification is required every 5 years with 25 recertification points earned through training, work, professional activity, or re-examination. An annual renewal fee (~$85) keeps the credential active.

The STSC is 100 multiple-choice questions in a 2-hour computer-based exam at Pearson VUE. You need a scaled score equivalent to 70% (approximately 70/100) to pass. Scores are delivered immediately after you submit the exam.

The Fatal Four are the leading causes of construction fatalities tracked by the BLS Census of Fatal Occupational Injuries (CFOI): falls, struck-by object, caught-in/between, and electrocutions. They cause roughly 60% of the 1,000+ construction worker deaths each year. OSHA's National Emphasis Programs and much of 29 CFR 1926 target these hazards, and they receive heavy weighting on the STSC.

Under 29 CFR 1926.501, workers on a walking/working surface with an unprotected edge that is 6 feet or more above a lower level must be protected by guardrails, safety nets, or a personal fall arrest system (PFAS). Note that scaffolds have a 10-foot trigger under Subpart L, and steel erection has its own threshold under Subpart R.
