What's the actual passing score for STSC? Getting conflicting info

Same boat a few months ago. Here's what I'd tell myself:

The STSC exam is more application-focused than the study guides suggest. They test whether you understand safety trained supervisor construction, not just whether you can define it.

My tip: when you see a scenario question, mentally walk through it step by step before looking at the answers. The wrong answers are designed to catch people who jump to conclusions.

Good luck — the fact that you're doing this level of prep means you're going to be fine.

The reason you're seeing 70 vs 75 is that BCSP doesn't actually publish a flat percentage for the STSC — it's a scaled cut score, so the "raw" number you need can shift a bit depending on which form of the exam you draw. Stop chasing the exact figure. It's not state-by-state either, that's people confusing it with state-specific safety cards. Aim to be comfortably above 75% on practice material and you stop having to care what the real cutoff lands at.

Here's the tip that actually moved my score: don't study the domains evenly. Pull up the BCSP blueprint and find the two heaviest-weighted areas (worksite safety/hazard recognition and the OSHA 1926 standards stuff carry way more questions than something like documentation), then drill those until they're automatic. I made a one-page sheet of just the 1926 subparts that keep showing up — fall protection triggers at 6 feet, scaffold requirements, excavation/trenching depth rules, the PPE selection logic — and reviewed it cold every morning. The exam loves scenario questions where you have to pick the violation, and those subpart numbers are what trip people up.

For drilling that, do timed sets of questions instead of just reading, because the STSC is as much about reading a long situational stem and not second-guessing yourself as it is about knowing the rule. I ran through this stsc practice test until the hazard-recognition ones stopped feeling like trick questions. Track which domain you keep missing, not just your overall percent. That's the part most people skip.

The 70 vs 75 confusion usually comes down to people mixing up STSC with the regular STS exam, or quoting old versions. For STSC specifically it's 70% to pass — and it's not state-by-state like you'd think, since it's an SSPC/BCSP credential, so the cutoff is the same wherever you sit it. The website being vague doesn't help, but 70 is the number.

Here's the study tip that actually moved my score though: don't just read the domains, weight your time by how the exam is split. The construction safety management and hazard recognition sections carry way more questions than the regulatory/admin stuff, so I spent maybe 60% of my prep on fall protection, excavation/trenching, scaffolding, and electrical hazard scenarios. The questions are situational — they'll describe a jobsite setup and ask what the supervisor does first — so memorizing OSHA citation numbers is mostly wasted effort. Knowing the hierarchy of controls cold and being able to spot the competent-person requirement in a scenario is what carries you.

What sealed it for me was drilling timed question sets until that 70% felt comfortable with margin, not just barely scraping it. I ran through this stsc practice test over and over and tracked which scenario types I kept missing — turned out trenching and confined space were my weak spots every time. Fix the pattern, not the one question. Once you're consistently hitting low 80s on practice, the real thing feels routine.
