The STSC Exam at a Glance

The Safety Trained Supervisor Construction (STSC) is the Board of Certified Safety Professionals' (BCSP) supervisor-tier construction safety credential. It is the construction-specific sibling of the general-industry STS and is purpose-built for foremen, general foremen, superintendents, project managers, and construction supervisors who have hands-on crew responsibility but are not full-time safety professionals.

Unlike the ASP or CSP, STSC is designed for construction supervisors whose primary role is not full-time safety practice. Its official blueprint assesses construction hazard control, program implementation, industrial hygiene, emergency management, leadership, and ethics. Employer and project requirements vary, so confirm whether a specific role recognizes STSC.

What the STSC Is and Why It Matters in 2026

BCSP offers two "Safety Trained Supervisor" credentials: the STS (general industry) and the STSC (construction). They share the same underlying logic — validate a working supervisor's command of safety fundamentals — but differ in regulatory scope. STS candidates reference 29 CFR 1910 (general industry); STSC candidates reference 29 CFR 1926 (construction).

This matters because construction supervision is legally and practically different from general industry. The OSHA Focus Four hazards — Falls, Struck-by, Electrocution, and Caught-in/between — account for the majority of construction fatalities every year per BLS Census of Fatal Occupational Injuries (CFOI) data. Construction supervisors who pass the STSC have demonstrated that they can recognize these hazards on their own jobsite, apply the right 1926 subpart, and lead abatement without waiting for a corporate safety officer to arrive.

Why a supervisor may consider STSC in 2026:

  1. Construction-specific scope. The official blueprint tests implementation, hazard control, industrial hygiene, emergency management, leadership, and ethics in construction settings.
  2. Experience-based eligibility. One pathway uses construction supervision or field experience rather than a degree, alongside the required 30 hours of safety, health, and environmental training.
  3. Portable BCSP credential. STSC can document construction-safety knowledge, but hiring, promotion, reimbursement, and project requirements remain employer-specific.

STSC vs STS vs ASP vs CSP vs CHST — Decision Matrix

Use this comparison as an orientation, then verify every credential on its current BCSP page. Fees below use the published app+exam combinations available at the last review.

CredentialTypical audienceWhat to verify before choosing
STSCConstruction foremen and supervisors30 training hours plus one current STSC eligibility pathway
STSSupervisors outside constructionCurrent STS industry scope, eligibility, blueprint, and fees
CHSTConstruction safety practitionersCurrent CHST safety-duty experience, blueprint, and fees
ASPSafety professionals considering a CSP pathwayCurrent education, experience, credential, blueprint, and fees
CSPExperienced safety professionalsCurrent degree, experience, qualifying credential, blueprint, and fees

Quick rules of thumb:

  • Foreman/superintendent running a construction crew? STSC.
  • Dedicated construction safety officer (full-time safety duty)? CHST.
  • Degree-holder pursuing corporate EHS career? ASP → CSP.
  • General-industry supervisor (not construction)? STS.

Many candidates stack credentials over a career: STSC in Year 1, CHST in Year 3, ASP in Year 5, CSP in Year 8. Others stop at STSC — it is a legitimate terminal credential for a career construction supervisor.


Eligibility Requirements (2026)

BCSP sets one training requirement plus one of four experience pathways for STSC eligibility. All must be satisfied at time of application.

Requirement: Safety and Health Training (30 hours minimum)

Candidates must document at least 30 hours of safety, health, and environmental training. BCSP commonly accepts:

  • OSHA 30-Hour Construction Outreach card (the most common path)
  • Equivalent employer-delivered training of 30+ hours, documented with sign-in sheets and topic agendas
  • Combination of shorter courses (CPR, First Aid, Scaffold Competent Person, Fall Protection Competent Person, Excavation Competent Person) totaling at least 30 hours
  • Degree coursework in SH&E (transcripts required)

The OSHA 30 Construction card is the cleanest documentation. If you are building from shorter classes, keep a training log with dates, durations, instructor names, and certificates.

Experience: Meet ONE of Four Pathways

BCSP accepts any one of the following in lieu of a degree:

  1. Two (2) years of supervisory experience related to construction — foreman, general foreman, superintendent, or project manager roles with authority to direct work, enforce safety rules, and stop work for imminent danger.
  2. Four (4) years of work experience related to construction — minimum part-time (18 hours/week) to qualify. Residential, commercial, industrial, heavy civil, highway, and utility construction all count; maintenance supervision in a manufacturing plant does NOT (that is STS territory).
  3. Associate degree or higher in occupational safety, risk management, or construction management.
  4. Completion of a two (2) year trade or union training program/apprenticeship.

Trade-specific supervision (electrical foreman, plumbing foreman, concrete foreman, crane signalperson foreman) is accepted under the supervisory pathway.

Common Eligibility Rejections

  • OSHA 10 only. OSHA 10 is not sufficient — BCSP requires 30 hours. Upgrade to OSHA 30 Construction before applying.
  • Supervision of office staff. Office supervision does not count toward the construction supervisory pathway. The duty must be on a construction jobsite under 29 CFR 1926.
  • Project engineer without crew authority. Project engineers who advise but do not direct workers typically do not qualify for the supervisory pathway — BCSP looks for authority to direct work and stop work for hazards.
  • Non-construction experience under the supervisory pathway. General-industry supervision belongs to the STS, not the STSC. Use the 4-year construction work-experience pathway if your supervision was not construction-related.

STSC Exam Blueprint (2026) — The STSC7 Blueprint

BCSP publishes a formal, percentage-weighted blueprint for the STSC (the STSC7 Examination Blueprint, V.2020.03.27). The exam is split into five content domains, each containing Knowledge questions, and two domains also containing Skills questions. BCSP publishes a two-hour computer-based exam but does not state a numeric item count or passing score on its current public STSC page. Use the official blueprint weights—not an assumed question count—to allocate study time.

DomainWeightWhat it tests
1. Safety Program Implementation and Management23.9%Established ESH programs, respiratory protection, incident investigation, job/task hazard analysis, HazCom, sanitation, permit-required work, chain-of-command escalation; Skills: evaluate worker qualifications/fitness, identify safe/unsafe behaviors, conduct inspections/audits, mitigate hazards, implement corrective actions and controls
2. Hazard Identification and Control28.5%Hot work, electrical, excavation, confined space, hazardous energy, work zones, material handling, struck-by/caught-between, pinch points, spill response, PPE, working at heights, walking/working surfaces, housekeeping, hand/power tools, heavy equipment, cranes, rigging/signaling, hierarchy of controls; Skills: identify site-layout risks, select PPE for tasks
3. Health Hazards and Basic Industrial Hygiene17.8%Ergonomic hazards, thermal stress, hearing protection, chemical hazards; Skills: recognize ergonomic/thermal-stress signs, identify routes of entry/exposure, implement health-hazard controls
4. Emergency Preparedness and Management16.6%Fire prevention/protection use and inspection, fire hazards/controls, emergency response plans and drills, required emergency equipment, medical emergency response; Skills: identify correct fire-extinguishing methods
5. Leadership and Ethics13.2%Professional and organizational ethics, BCSP Code of Ethics: Principles; Skills: apply the BCSP Code of Ethics (Leadership, Integrity, Diversity and bias)

Domain 2 (Hazard Identification and Control) is the largest and is where the OSHA Focus Four, scaffolds, excavations, confined spaces, cranes, and PPE content lives. Master Domain 2 and you have nearly 29% of the exam locked in.


Focus Four Deep Dive (Heavily-Tested Domain 2 Content)

The OSHA Focus Four are the four hazard categories that cause the most construction fatalities each year. They fall under Domain 2 (Hazard Identification and Control, 28.5%) on the STSC7 blueprint, so expect a heavy concentration of items here. Master the Focus Four and you have the largest single chunk of the exam locked in.

1. Falls (29 CFR 1926 Subpart M)

Falls are the #1 killer in construction — roughly 36% of all construction fatalities per BLS CFOI. Memorize these triggers:

  • 6-foot rule (construction). Fall protection is required at 6 feet or more above a lower level in construction — this is different from general industry (4 feet under 1910). The STSC tests this distinction constantly.

  • Unprotected sides and edges. 29 CFR 1926.501(b)(1) requires guardrails, safety nets, or personal fall arrest systems (PFAS) at 6 ft.

  • Leading edge work. 1926.501(b)(2) — same 6 ft trigger, specific rules for formwork and steel erection.

  • Holes. 1926.501(b)(4) — covers, guardrails, or PFAS for holes 6 ft or deeper; trip protection for holes of any depth.

  • Roofing work on low-slope roofs. 1926.501(b)(10) — options include guardrail, safety net, PFAS, warning line + safety monitor, or (for residential) a written fall protection plan.

PFAS arrest vs restraint vs positioning — know the distinction (this is a classic pitfall):

  • Fall Arrest (ANSI Z359.11, Z359.13) — stops a worker AFTER they begin to fall. Requires a full-body harness, shock-absorbing lanyard, and anchor rated for 5,000 lb per person (or 2× max arresting force engineered system). Max arresting force: 1,800 lb.
  • Fall Restraint — prevents the worker from reaching the fall hazard in the first place. Can use a body belt (restraint only — never arrest). Anchor rated for 1,000 lb minimum.
  • Positioning — holds worker in place to work hands-free on a vertical surface (rebar, formwork, pole climbing). Positioning systems must also be backed up by fall arrest if a fall is possible.

Candidates routinely miss items where the scenario describes restraint but the answer options include arrest equipment. Read the scenario twice.

2. Struck-by (29 CFR 1926 Subparts N, O, CC, and others)

Struck-by hazards are roughly 10% of construction fatalities. Exam content draws from:

  • Crane operations (1926 Subpart CC). Swing radius barricading — no worker in the swing radius unless a signalperson is in direct visual contact. Load path clearance. Certified operator requirement (NCCCO or equivalent).
  • Rigging. Competent person for rigging inspection. Sling angle derate (60° horizontal = 86.6% of rated capacity; 30° = 50%). Tagline use for wind.
  • Overhead power lines (1926.1408). Minimum clearance 20 ft for lines up to 350 kV; 10 ft for < 50 kV (power line proximity table heavily tested).
  • Falling objects (1926.451(h)). Toeboards, debris nets, catch platforms, canopies.
  • Vehicle/traffic zones (1926.202). High-visibility clothing (ANSI 107 Class 2 or 3), flaggers, signs, cones, barriers per MUTCD Part 6.

3. Electrocution (29 CFR 1926 Subpart K and V)

Electrocution accounts for roughly 8% of construction fatalities. Key content:

  • Overhead power line clearance. 10 ft minimum for lines up to 50 kV (non-crane work). Cranes follow 1926.1408 table (20 ft default).
  • LOTO (29 CFR 1910.147 applied via 1926). Energy isolation, verification, tryout, authorized/affected employee training.
  • GFCI or Assured Grounding. 1926.404(b)(1)(ii) — all 120 V single-phase 15/20A receptacles on a jobsite must be GFCI-protected OR covered under an Assured Equipment Grounding Conductor Program.
  • Arc flash (NFPA 70E). Construction electrical supervisors should know NFPA 70E categories (CAT 1-4), incident energy calc basics, boundary distances (arc flash boundary, limited approach, restricted approach).
  • Temporary wiring. Strain relief, no splices in flexible cord, protection from physical damage.

4. Caught-in/between (29 CFR 1926 Subparts P, O, and others)

Caught-in/between accounts for roughly 7% of construction fatalities. Most heavily tested:

  • Trench cave-ins (Subpart P). All trenches 5 ft and deeper must be protected by sloping, benching, shoring, or shielding UNLESS excavated entirely in stable rock. Trenches 20 ft+ require a registered PE-designed system.
  • Soil classification.
    • Type A — most stable (clay, silty clay). Max slope 3/4:1 (53°).
    • Type B — moderate (angular gravel, silt). Max slope 1:1 (45°).
    • Type C — least stable (granular, submerged soils, sand). Max slope 1.5:1 (34°).
  • Competent person required daily. Before entry, after every rainstorm, and after any event that could change soil conditions. Atmospheric testing required if trench > 4 ft deep with reasonable expectation of hazardous atmosphere.
  • Spoil pile setback. Minimum 2 ft from edge.
  • Heavy equipment. Operator sight lines, backup alarms (1926.601), spotter use.
  • Machine guarding (1910.212 via 1926). Point of operation, power transmission apparatus, pinch points.

Other Construction Hazards Tested on the STSC

Scaffolds (29 CFR 1926 Subpart L)

  • Load ratings. Light-duty 25 psf, medium 50 psf, heavy 75 psf. Scaffold + rated load must not exceed 4× maximum intended load.
  • Competent person inspection. Required before each work shift and after any event affecting structural integrity.
  • Fall protection on scaffolds. Guardrails for scaffolds 10 ft or higher. PFAS required on suspended, boatswain's chair, and float scaffolds.
  • Access. Ladder, stair tower, ramp, or integrated prefab stairs — climbing cross-braces prohibited.
  • Platform construction. Planks must extend 6-12 inches past supports (cleated) or 6-18 inches (uncleated).

Ladders (Subpart X)

  • Portable ladders extend 3 ft above landing. Secure top and bottom.
  • Angle 4:1 (rise to run).
  • Competent person inspection before use. Damaged ladders tagged "Do Not Use."
  • Defective ladder. Withdraw from service immediately.

Excavation (Subpart P)

See Caught-in/between section above. Additional STSC content: utility locates (811 one-call), excavation permit programs, water accumulation controls.

Confined Space (29 CFR 1926.1200 Subpart AA)

Construction confined space rule became effective 2015 and is heavily tested:

  • Permit-Required vs Non-Permit-Required. Permit-required = contains or has potential to contain serious atmospheric or engulfment/entrapment hazard.
  • IDLH atmosphere. Immediately Dangerous to Life or Health — requires SCBA, attendant, rescue plan.
  • Atmospheric testing sequence. Oxygen (19.5-23.5%), flammability (< 10% LEL), toxicity (below PEL).
  • Entry team roles. Entrant, Attendant, Entry Supervisor — each has specific 1926.1209 duties.
  • Rescue. Non-entry rescue preferred; entry rescue requires trained, equipped team on-site or within response time.

Hot Work

  • Fire watch required during and 30 minutes after hot work per 1926.352 and NFPA 51B.
  • Permit system. Identify combustibles, shielding, extinguisher availability.
  • IDLH atmospheres. Do not perform hot work in confined spaces without atmospheric verification and permit controls.

Cranes (Subpart CC)

Qualified operator (NCCCO or equivalent), qualified signalperson, qualified rigger, annual inspection, pre-shift inspection, assembly/disassembly per manufacturer, power line proximity controls.

PPE (Subpart E)

Hazard assessment (1926.95), head protection (ANSI Z89.1), eye/face (ANSI Z87.1), hand, foot (ASTM F2413), hearing (above 85 dBA TWA), respiratory (1910.134 via 1926).

SDS / HazCom (29 CFR 1926.59 → 1910.1200)

Safety Data Sheets (16-section GHS format), container labeling (GHS pictograms), written program, employee training.

Heat and Cold Stress

OSHA's heat illness prevention campaign (water, rest, shade). WBGT monitoring. Acclimatization schedule for new and returning workers. Cold stress: hypothermia, frostbite, PPE layering.


OSHA Recordkeeping on the STSC (29 CFR 1904)

Recordkeeping appears in Domain 1 (Safety Program Implementation and Management). Supervisors must know the logs by name and function:

  • OSHA Form 300 — Log of Work-Related Injuries and Illnesses. Maintained live.
  • OSHA Form 300A — Annual Summary. Posted February 1 through April 30 each year.
  • OSHA Form 301 — Injury and Illness Incident Report. Completed within 7 calendar days of event.

Reporting triggers (1904.39):

  • Fatality — report to OSHA within 8 hours.
  • In-patient hospitalization, amputation, or loss of an eye — report within 24 hours.

Electronic submission (1904.41) required for establishments with 100+ employees in designated high-hazard industries (construction included).


Accident Investigation, Return-to-Work, and Safety Culture

Incident investigation and safety culture are tested in Domain 1 (Safety Program Implementation) and Domain 5 (Leadership and Ethics). Expect several items across these supervisor-soft-skill areas:

  • Root cause analysis. 5 Whys, Fishbone/Ishikawa, Fault Tree basics. The goal is systemic cause, not "operator error."
  • Witness interviews. Separate interviews, open-ended questions, no blame language.
  • Return-to-work / modified duty. Transitional duty programs reduce workers' comp cost and speed recovery.
  • Safety culture. Heinrich's triangle (no longer cited as a ratio but the concept appears), Reason's Swiss Cheese Model, just culture vs blame culture.
  • Leading vs lagging indicators. Leading: near-miss reporting, JHA completion, training hours. Lagging: TRIR, DART, fatality count.

Registration via Pearson VUE

After BCSP issues your Authorization to Test (ATT), follow its current Pearson VUE scheduling instructions and choose an available test-center appointment. BCSP's current public STSC page lists Pearson test-center delivery and a two-hour exam. Follow the identification, arrival, rescheduling, and permitted-material instructions in your appointment confirmation.


Recertification (BCSP 5-Year Cycle)

The STSC recertifies on a 5-year cycle. Per the BCSP Complete Guide, STSC holders must earn and submit three (3) points (30 hours) of safety and health courses, OR earn another qualifying BCSP credential (STS, CIT, CHST, OHST, ASP, SMS, or CSP), within each five-year window.

  • Most common path: 30 hours of safety and health continuing education (OSHA 500/510, trade-association CEUs, ASSP conference sessions, employer-delivered training) — documented and submitted through the BCSP portal.
  • Alternative path: earn the STS, CIT, CHST, OHST, ASP, SMS, or CSP during the cycle, which satisfies recertification in full.

The At-A-Glance document lists a $70 annual renewal. Track your cycle in the BCSP portal and follow the current renewal, ethics, recertification, suspension, and reinstatement policies rather than assuming another BCSP credential uses the same rules.


6-8 Week Study Plan

BCSP does not publish a required study duration or a first-attempt pass-rate breakdown. The 40-60 hour, 6-8 week plan below is an editorial starting point; shorten or extend it using your blueprint-domain results.

Week 1 — Foundation

  • Read 29 CFR 1926 Subpart C (General Safety and Health Provisions) and Subpart D (Occupational Health and Environmental Controls).
  • Review OSHA Focus Four Hazards poster and study notes. Commit fatality statistics to memory.
  • Set up your BCSP candidate portal and confirm ATT is valid.

Week 2 — Focus Four Part 1 (Falls + Struck-by)

  • 29 CFR 1926 Subpart M (Fall Protection). Memorize the 6-ft trigger and PFAS vs restraint vs positioning distinction.
  • Subpart L (Scaffolds) — load ratings, competent person, fall protection on scaffolds.
  • Subpart CC (Cranes) — rigging, swing radius, power line proximity.
  • Practice: Falls and Scaffolds

Week 3 — Focus Four Part 2 (Electrocution + Caught-in/between)

  • Subpart K (Electrical) — LOTO, GFCI, overhead line clearance.

  • Machine guarding carryover from 1910.212.

Week 4 — Construction-Specific Hazards

  • Subpart AA (Confined Spaces in Construction) — permit vs non-permit, atmospheric testing sequence.
  • Subpart X (Ladders and Stairways).
  • Subpart H (Materials Handling, Storage, Use, Disposal).
  • Hot work, NFPA 51B fire watch requirements.

Week 5 — Program Management + Recordkeeping

  • 29 CFR 1904 (Recordkeeping) — 300, 300A, 301 logs. Reporting timelines.
  • JHA authoring, pre-task planning, toolbox talks.
  • Accident investigation methods (5 Whys, fishbone, Swiss cheese).
  • SDS / GHS / HazCom (1926.59).

Week 6 — PPE + Soft Skills + Mock Exam

  • Subpart E (PPE) — ANSI standards for head, eye, face, hand, foot, hearing.
  • Heat/cold stress, respiratory protection basics.
  • Full 2-hour mock exam under test conditions.
  • Review wrong answers. Build a "miss log."

Weeks 7-8 (Buffer) — Targeted Reinforcement

  • Focus on your miss log from the Week 6 mock.
  • Second full mock at end of Week 7.
  • Light review Week 8. Do NOT cram the day before.

  • ASSP Construction Practice Specialty — offers member webinars and conference sessions that double as recertification credit.

Test-Day Strategy

  • Follow your appointment confirmation. Arrive at the Pearson test center with the identification it requires.
  • Budget the published two hours. Once the exam displays its item count, reserve time for review and pace the remaining items accordingly.
  • First pass. Answer items you can resolve efficiently and flag longer scenarios for review.
  • Second pass — return to flagged items. Re-read the scenario before looking at options. Eliminate obviously wrong answers first.
  • Review before submission. Return to flagged or unanswered items and use elimination when the interface permits changes.
  • Watch for absolute qualifiers. "Always," "never," and "only" are often wrong on regulatory items. "Generally," "typically," and "often" match OSHA's language better.
  • Unit check. 6 ft, 10 ft, 20 ft, 5 ft, 4 ft, 4:1 — construction triggers are memorizable. If an answer option mismatches the trigger you memorized, eliminate it.

Common Pitfalls and How to Avoid Them

  1. Memorizing Focus Four without scenario practice. The exam does not ask "what is a fall hazard" — it gives you a 60-word scenario about a framer on a parapet wall and asks for the correct abatement. Practice scenario-based items, not term definitions. Start FREE STSC Practice -->
  2. Confusing PFAS arrest with restraint with positioning. Restraint PREVENTS the fall; arrest CATCHES the fall; positioning HOLDS you in place. Body belts are restraint-only — never arrest.
  3. General industry triggers vs construction triggers. General industry fall protection triggers at 4 ft; construction at 6 ft. Many candidates arrive with 1910 training and miss the 1926 distinction.
  4. OSHA 8-hour fatality trigger vs 24-hour hospitalization trigger. Do not confuse them.
  5. Competent vs Qualified Person. Competent person = identifies hazards, authorized to correct. Qualified person = recognized training/experience to solve the problem (typically engineering-level). Roles are non-interchangeable on the exam.
  6. Trench depth triggers. Protective system at 5 ft (unless stable rock). PE-designed system at 20 ft. Atmospheric testing at 4 ft when hazardous atmosphere possible.
  7. GFCI vs Assured Grounding confusion. Both are acceptable under 1926.404(b)(1)(ii) — GFCI is more common, but Assured Grounding Conductor Program is the compliant alternative when GFCI isn't feasible.
  8. Scaffold cross-brace climbing. Prohibited. Ladder, stair tower, ramp, or integrated stairs only.
  9. Crane swing radius barricading. Workers out of radius unless in direct visual contact with signalperson. Radius barrication is non-negotiable.
  10. Relying only on OSHA 30 content. OSHA 30 covers much of the hazard-identification content but not the full STSC7 blueprint — Leadership and Ethics (Domain 5), Emergency Preparedness (Domain 4), and program-management/recordkeeping skills require targeted study beyond OSHA 30.

Career Value of the STSC

Career outcomes vary. BCSP does not publish a guaranteed salary premium, promotion rate, employer-reimbursement rate, or list of projects that require STSC. Treat the credential as evidence of knowledge—not a promise of compensation or employment.

Related credential planning. Construction supervisors who later move into dedicated safety roles can compare the current CHST, ASP, and CSP eligibility rules and blueprints. Choose a next credential only after checking that your education and work duties satisfy its official requirements.

Employer and project requirements. Ask the relevant employer, union, contractor, client, or procurement system whether it recognizes STSC for the role or project in question; requirements are organization-specific and can change.
