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.

BCSP lists a $120 application, $185 exam, $293 app+exam combo, and $70 annual renewal. STSC recertification uses a five-year cycle with 3 points (30 hours) plus applicable ethics requirements. Confirm current fees with BCSP.

BCSP publishes a two-hour computer-based STSC exam at Pearson test centers, with results available after submission. Its current public STSC page does not publish a numeric question count or passing score.

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.

Use OpenExamPrep's 100-question practice bank as a study resource, not as the official exam length. Follow BCSP's STSC7 blueprint: Hazard Identification and Control 28.5%, Safety Program Implementation 23.9%, Health Hazards and Basic Industrial Hygiene 17.8%, Emergency Preparedness and Management 16.6%, and Leadership and Ethics 13.2%. Review the cited OSHA standards, then drill weak domains with practice questions.
