Is there a Mohs technician certification?

There is no board certification specific to Mohs. The recognized credential is HT(ASCP), the histotechnician certification from the ASCP Board of Certification. Mohs-specific courses, such as those from the American Society for Mohs Histotechnology, give completion certificates rather than board certification.

Do I need HT(ASCP) to work as a Mohs tech?

Not in most states, and not to start with Mohs Pros. It is valued by employers and widens what you can do in the lab.

Does Mohs experience alone qualify me for HT(ASCP)?

Probably not on its own. ASCP experience must cover paraffin processing and special stains as well as frozen sections, so plan time in a full histology lab or a structured program.

Mohs technician certification

By the Mohs Pros teamLast updated October 10, 2026

The credential that matters for Mohs techs is HT(ASCP), the histotechnician certification from the ASCP Board of Certification. You don't need it to start, but it's recognized nationwide and is one of the things that moves pay up.

HT(ASCP): the main routes

Route	Education	Plus
1	A NAACLS-accredited histotechnician program, completed within the last 5 years	Nothing else
2	60 semester hours or an associate degree, including 12 semester hours of biology and chemistry (both)	1 year of full-time histology experience within 5 years, or a structured program of at least 9 months with at least 480 clinical hours
3	Military histology course of at least 50 weeks	As specified by ASCP

Summary of the ASCP HT requirementsas of October 2026. Always check ASCP for the current rules and fees before applying.

The catch for Mohs techs

ASCP experience must cover the whole histology bench: fixation, processing, embedding and cutting in paraffin and frozen, routine and special stains, and lab operations. Mohs work is frozen sections with routine stains, so most Mohs techs add time in a full histology or dermatopathology lab, or complete a structured program.

HTL(ASCP)

The histotechnologist credential needs a bachelor's degree, plus either a NAACLS-accredited histotechnology program or biology and chemistry coursework with a year of experience or a structured program. It suits techs heading toward supervisory roles.

How long it takes

Starting with a high school diploma, plan on about 2 to 3 years while working: roughly 2 years of part-time college to reach 60 semester hours with biology and chemistry, alongside the year of qualifying experience. Online NAACLS programs exist, such as Indiana University's histotechnology certificate, with clinical practice at your own lab.

State licenses

Most states don't license histotechs. New York, Nevada andPuerto Rico do; Louisiana and Montana are unclear. Many states exempt labs run by physicians for their own patients. California doesn't license histotechs: unlicensed lab staff need a high school diploma and documented training.
