When you register for the class they send you a packet that has most things you need, as well as a supplemental list of books for it. You need to understand what the purpose of a CTSP is if you're getting it for your employer.
The purpose is to build the applicant into a trainer and motivated safety integrator. Depending on the company, you could end up the investigator, a scapegoat for problems (if it's a shitty company), or as the operations lead. It gives a high level overview into how humans think, the psychology of education in adults, how to critically think and problem solve, and more. It's meant to help the person solve problems in their careers more efficient so that new technologies, innovations, and safety improvements (including the new ANSI standards) are implemented thoroughly.
I say this because often people get it, get shouldered with a mountain of new job tasks, and may or may not be compensated properly for their new roles. I would discuss what changes will come for you with your employer when you get the certification and what roles they hope to have you fill with your new education/certification.
It's a really solid program, much more than a money grab if you are serious about the trade and your career progression. Safety is huge, and much of it comes from efficiency and understanding how to read what your constituents need. I loved being a part of the safety team at a big 4 company. At my own company, the ctsp helps me to educate, train, organize, and adapt to changes with clearly attainable measures of success i.e. close call reporting, dvir and inspections, and training compilation with check ins.
