Practice as a clinical laboratory technologist and the use of the title "clinical laboratory technologist" in New York State require licensure, unless otherwise exempt under the law.

To be licensed as a clinical laboratory technologist in New York State you must meet all requirements, including:

  • submit the application and fee for initial licensure;
  • be of good moral character;
  • be at least 18 years of age;
  • meet education or alternative to education requirements; and
  • meet examination requirements.

You must file an application for licensure and the other forms indicated, along with the appropriate fee, to the Office of the Professions at the address specified on each form. It is your responsibility to follow up with anyone you have asked to send us material.

The specific requirements for licensure and definition of practice are contained in Title 8, Article 165 of New York's Education Law and Subpart 79-13 of the Regulations of the Commissioner of Education. The laws and regulations are available on this website.

You should also read the general licensing information applicable for all professions.

The licensure and first registration fee is $345.

The limited permit fee is $50 (the limited permit fee is not refundable).

The fee for a provisional permit is $50 (the provisional permit fee is not refundable).

Fees are subject to change. The fee due is the one in law when your application is received (unless fees are increased retroactively). You will be billed for the difference if fees have been increased.

  • Do not send cash.
  • If you apply for licensure electronically using the online Application for Licensure, you will be required to pay by credit card.
  • Other payments must be made by personal check or money order payable to the New York State Education Department. Your cancelled check is your receipt.
  • Mail any required forms and fees to the indicated address on the form.

NOTE: Payment submitted from outside the United States should be made by credit card, check or draft on a United States bank and in United States currency; payments submitted in any other form will not be accepted and will be returned.

Individuals who withdraw their licensure application may be entitled to a partial refund.

  • For the procedure to withdraw your application, contact the Clinical Laboratory Technology Unit by e-mailing opunit2@nysed.gov or by calling 518-474-3817 ext. 260 or by faxing 518-402-2323.
  • The State Education Department is not responsible for any fees paid to an outside testing or credentials verification agency.

A limited permit authorizes an individual who has met all requirements for licensure as a clinical laboratory technologist, except for the examination requirement, to practice clinical laboratory technology in a specific setting.

The permit is valid for not more than 24 months and is not renewable. The permit holder shall be under the general supervision of the director of a clinical laboratory. Limited permit holders may not work at more than one clinical laboratory at a time. A limited permit holder who seeks to work in a different clinical laboratory must submit a new limited permit application to practice in such clinical laboratory and may not start practice until the limited permit is issued for the new setting and supervisor.

The supervising clinical director must serve the laboratory full-time, or on a regular part-time basis; ensure the supervision and technical performance of the limited permit holder, and be readily available for consultation with the limited permit holder, as needed; shall be responsible for the performance and findings of all tests carried out by the limited permit holder, either by directly overseeing such testing or by assigning qualified supervisors to provide onsite supervision of the permit holder.

If the clinical laboratory director named on the limited permit ceases to supervise the limited permit holder or is replaced by another clinical laboratory director, the limited permit holder must submit a new limited permit application form identifying the new director to the Department. The limited permit holder may only practice under the supervision of the clinical laboratory director when the new permit is issued; the limited permit will be issued for the unused portion of the 24-month limited permit period.

A provisional permit authorizes an applicant for licensure to practice clinical laboratory technology under supervision  in a specific setting. The provisional permit is valid for not more than 24 months and is not renewable.   The provisional permit holder shall be under the general supervision of the director of a clinical laboratory. Provisional permit holders may not work at more than on clinical laboratory at a time. A provisional permit holder who seeks to work in a different clinical laboratory must submit a new provisional permit application to practice in such clinical laboratory and may not start practice until the provisional permit is issued for the new setting and supervisor.

If the clinical laboratory director named on the provisional permit ceases to supervise the provisional permit holder or is replaced by another clinical laboratory director, the provisional permit holder must submit a new provisional permit application form identifying the new director to the Department. The provisional permit holder may only practice under the supervision of the clinical laboratory director when the new permit is issued; the provisional permit will be issued for the unused portion of the 24-month provisional permit period.

The provisional permit holder must work under the general supervision of a clinical laboratory director at the clinical laboratory named on the provisional permit.
