To become a histotechnologist you usually need a bachelor's degree, typically in a life science or clinical laboratory science, plus training in preparing tissue samples for pathologists. Some states require clinical laboratory staff to be licensed, and employers may prefer certified candidates. Histotechnicians, a related role, sometimes start with an associate degree.
Histotechnologists prepare the slides pathologists use to diagnose disease. When a surgeon removes a biopsy, it's the histology lab that fixes, embeds, cuts and stains it so a doctor can see what's happening at the level of the cell. It's precise, hands-on lab work with a direct line to patient care.
I've built this guide from two official sources read as of October 2026: the O*NET OnLine profile for histotechnologists, run for the US Department of Labor, and the Bureau of Labor Statistics Occupational Outlook Handbook profile for clinical laboratory technologists and technicians. It's a careers guide, not clinical advice.
Histotechnologist or histotechnician?
| Histotechnologist | Histotechnician | |
|---|---|---|
| Typical education | Bachelor's degree | Sometimes an associate degree |
| Main work | Tests on human tissue to identify disease, plus evaluating new techniques | Cutting and staining tissue specimens for pathologists |
| BLS grouping | Clinical laboratory technologist | Clinical laboratory technician |
BLS treats both as specialties within clinical laboratory work. The technologist role usually carries more responsibility, including solving technical problems and helping with research studies, according to O*NET.
What education do you need?
O*NET asked people working as histotechnologists what a new hire needs. 43% said a bachelor's degree, 19% said an associate degree or other 2-year degree, and 14% said a post-secondary certificate. O*NET places the job in Job Zone Four, which means considerable preparation, and most jobs in that zone need a four-year degree.
BLS suggests high school students interested in lab careers take chemistry and biology. At university, a degree in a life science or a clinical laboratory science program gives you the lab hours employers look for.
How to become a histotechnologist, step by step
- Take science early. Chemistry and biology at school set you up for a lab degree.
- Earn a bachelor's degree. It's what most new hires have. Clinical laboratory science programs may include clinical experience.
- Learn histology techniques. Embedding, cutting with a microtome and staining are the core skills, and they take practice.
- Check your state's rules. BLS says some states require laboratory personnel to be licensed or registered, with requirements that vary by state and specialty. In some states, licensure requires certification.
- Get certified. Even where it isn't required, BLS says employers may prefer to hire certified candidates.
What you'll do in the lab
O*NET lists the tasks histotechnologists do most often. You'll:
- embed tissue specimens in paraffin wax blocks
- cut thin sections of tissue for microscopic examination using microtomes
- stain specimens with dyes or chemicals so cell details show up under the microscope
- prepare reagents, dilutions and stains according to protocols
- run computerised equipment that dehydrates or decalcifies tissue samples
- compile slides and paperwork for pathologists and keep instrument maintenance records
Sample job titles O*NET lists include histology technologist, histology specialist and histology lab manager, so there's a clear route up into supervision.
Pay and outlook
O*NET doesn't publish a separate wage for histotechnologists. It uses the wider clinical laboratory technologists and technicians figure, which BLS puts at a median of $62,930 a year in May 2025, as of October 2026. That group held 343,000 jobs in 2025, with health care the top industry.
BLS projects employment of clinical laboratory technologists and technicians to grow 3% from 2025 to 2035, about as fast as average, and O*NET projects 20,800 openings over the decade. Histology is a specialty within that, so experienced, certified histotechs tend to be in demand.
Skills that help in a histology lab
O*NET's task list points to the skills that matter most. Steady hands come first, because cutting sections on a microtome takes practice and patience. After that, you'll need:
- attention to detail when following staining and reagent protocols
- careful record keeping for instrument checks and maintenance
- comfort with computerised lab equipment
- the ability to solve technical or instrument problems when a run goes wrong
There's also a clear ladder. O*NET's sample job titles run from histotechnologist and histology specialist up to histology lab manager and clinical lab manager, so the job can lead into supervision once you've got experience. Some histotechnologists also help with research studies, which suits people who like the science behind the slides.
Want AI doing the heavy lifting in your marketing?
I build the systems that handle the boring 80 percent, so you get your week back. Done properly, with the human kept in.
One honest warning: histology labs often run to the surgical schedule, because specimens arrive as operations finish. Ask about shift patterns and weekend cover at interview, so you know what a normal week looks like before you accept a job. It's a small question that saves a lot of surprises later.

My verdict
Histotechnology suits people who are patient, precise and happy at a bench all day. Get a science degree, learn the cutting and staining skills, and check your state's licensing rules before you apply. Certification is worth getting early, because it's what many employers ask for even where the law doesn't.
Frequently asked questions
What degree do you need to be a histotechnologist?
Most have a bachelor's degree. In O*NET's survey, 43% of histotechnologists said a new hire needs a bachelor's degree, and 19% said an associate degree.
How much do histotechnologists make?
O*NET uses the clinical laboratory technologists and technicians figure, a median of $62,930 a year in May 2025, as of October 2026.
Do histotechnologists need a licence?
In some states. BLS says some states require laboratory personnel to be licensed or registered, and in some states licensure requires certification.
What's the difference between a histotechnologist and a histotechnician?
BLS describes histotechnicians as clinical laboratory technicians who cut and stain tissue specimens, while histotechnologists are technologists who perform tests on tissue to identify diseases.
What does a histotechnologist do?
O*NET says they process and prepare histological slides from tissue sections for diagnosis by pathologists, including embedding, cutting and staining specimens.
Can histotechnologists move into management?
Yes. O*NET's sample job titles include histology lab manager and clinical lab manager, so experienced histotechnologists can move into supervision.
