These guides are organized by where you are, not by topic. Most people arrive here at one of four points: deciding whether to enter the field, finishing a program and trying to get hired, sitting in a staff CST role wondering what is next, or trying to understand which of five similar-sounding job titles they actually hold. Start at your stage.
You are researching whether this is the right field. The honest questions are what the day looks like, what the training costs in time, and how it differs from the adjacent roles you have also been reading about.
You are in a program or just out of one. The gap between graduating and getting hired is where most candidates lose months, and almost always for reasons they could have controlled.
You have the volume and the credential. The next move is either sideways into a specialty that pays more, or upward into assisting, leadership, or education. Specialty is the larger lever and the one most techs never pull.
Operating room technician, scrub tech, and surgical technologist usually name the same job. Surgical first assistant does not. Candidates who search under one title miss most of the postings they qualify for, and candidates who blur the last one on a resume get screened out.
