Histotechnician Certification - HT, HTL (ASCP)
Search For Schools
While no one wants the responsibility of delivering a disease diagnosis, early detection can help healthcare providers determine treatment plans to restore patients’ health and wellness. After a biological specimen is biopsied, patients may wonder: who is examining and testing their tissues for possible abnormalities? The answer is histotechnicians and histotechnologists.
The Greek word root “histo” means “organic tissue” and histotechnicians prepare living tissue samples for evaluation by using laboratory instruments to cut thin slices of tissue, place them on a microscope slide, and apply dyes to determine if there are abnormalities present. Histotechnicians and histotechnologists aid pathologists in determining disease diagnoses in medical or research laboratory roles. The information gathered from the biopsied tissue samples informs the appropriate treatment for specific patients and for future medical research.
As the healthcare sector continues to expand, so too are careers in histotechnology predicted to increase. The U.S. Bureau of Labor Statistics (BLS May 2021) shows that careers in clinical laboratory technology—a closely-related career to histotechnicians—are growing at a rate of 11 percent (2020-2030), which is much faster than the national average compared to all other occupations (8 percent).
Most entry-level positions require a bachelor’s degree and while licensure and certification requirements vary by state, most employers prefer to hire certified laboratory technicians (BLS 2021).
The American Society for Clinical Pathology (ASCP) Board of Certification (BOC) offers global certification for medical laboratory professionals. Since 1928, the ASCP has set high professional competency standards and certified more than 600,000 laboratory professionals.
While the National Society for Histotechnology (HST), a participating society with ASCP, strongly recommends certification, it’s worth noting that not all medical laboratory positions require histology certification. A study released by the ASCP in 2017 shows that laboratory positions in specimen processing and phlebotomy are less likely to require histology certification, while positions with blood banks and hematology/coagulation are more likely to require certification (HST 2018).
Despite certification being optional for some positions, the same study, which was published in the American Journal of Clinical Pathology (AJCP), goes on to say that the increasing rates of people retiring from histotechnician careers—combined with an increased number of certification requirements and low rates of occupational vacancy—means laboratory professionals would be well-served to pursue certification to prove their professional competency in a competitive job market.
Careers in histotechnology are about more than doing experiments in a laboratory; most histotechnician teams work collaboratively for a shared mission of providing quality patient care. In a video titled Preparing for a Histotechnology Career in the US by HST, histologist Lisa Paez-Ryan describes the career in detail:
Histologists have an interest in science and enjoy hands-on work. They like to work as part of a committed team of healthcare professionals. They provide information that can help doctors determine the best patient treatment. Just think: that person could be you.
Read on to learn more about the two main histotechnology certifications: histotechnician (HT) and histotechnologist (HTL), which are both available through the American Society for Clinical Pathology (ASCP).
Preparation for Histotechnology Certification
High school students aspiring to pursue histotechnology careers are advised to take as many chemistry, biology, and mathematics courses as possible to prepare them for coursework in post-secondary science degree programs. Coursework in computers and typing is also recommended since histologists are required to keep accurate laboratory notes.
Engaging in extracurricular activities related to science, math, and after-school team-building and activities in the arts or athletics could also be beneficial. Students are advised to keep their grades as high as possible to get into a reputable and accredited associate or bachelor’s degree program to prepare for histotechnology careers.
A list of schools with national and regional accreditation can be found at the U.S. Department of Education and a list of histology programs with programmatic accreditation can be found at the National Accrediting Agency for Clinical Laboratory Sciences (NAACLS) and on the main histotechnology education page.
The ASCP Board of Certification (BOC) offers two certifications in histology: histotechnician (HT) certification and histotechnologist (HTL) certification. Prospective applicants can check their eligibility status using the ASCP examination eligibility assistant.
Histotechnician (HT) ASCP Certification: Associate’s Degree

State Licensure Requirements in Histotechnology
The ASCP keeps a list of specific state licensure requirements for histotechnicians. State licensure requirements vary widely for histotechnicians, with some states requiring a state-specific licensure exam or a combination of a state-specific licensure exam and an ASCP certification exam.
Depending on their last certification date, additional requirements may exist for previously certified or licensed histotechnicians.
For example, the state of New York has three licensing pathways: 1) a New York state license only, 2) ASCP certification and New York state licensure, and 3) a licensure pathway for those who are already ASCP-certified.
Applicants are strongly recommended to research the licensing requirements unique to the states where they will work.
