So I've been trying to get my CHST for about 14 months now. Failed at 68% both times, which is honestly embarrassing to admit publicly, but I figure if my experience helps someone else it's worth it. The exam caught me off guard with how heavy it is on OSHA standards and hazard recognition scenarios — I kept focusing on the math-heavy stuff like accident rates and completely underestimated the behavioral/safety management sections.
What changed for my third attempt: I started using a dedicated CHST practice test site that actually mirrors the real question format. Timed simulations made a huge difference. I also built a proper study guide instead of just rereading my BCSP prep materials — I organized it by domain and tracked which areas I kept missing. Domains 1 and 3 were killing me.
Third time I passed at 76%. If anyone's struggling with similar issues, happy to share my full breakdown of what I studied and in what order. Took me about 9 weeks of focused prep, roughly 8-10 hours per week.
