International Cytotechnologist’s Requirements for US Employment
As stipulated by law in CLIA’88 (Clinical Laboratory Improvement Act of 1988), to meet the qualifications of a cytotechnologist one must have graduated from a school of cytotechnology accredited by CAHEA whose role is now being fulfilled by CAAHEP ( Commission on Accreditation of Allied Health Educational Programs). There are other pathways for cytotechnologists who are already employed within the United States to meet CLIA qualifications.

A listing of the CAAHEP accredited programs which are all located in the US and Puerto Rico is available on the ASCT website under the Student Forumand on the CAAHEP website.


ASCP Board of Certification: International Cytotechnologist
The ASCP now offers certification in Gyn cytology for international candidates. While obtaining the International Technologist in Gynecologic Cytology, CTgyn(ASCPi) certification demonstrates your commitment to the high standards that ASCP certification reflects; it is not a substitute for the US employment requirements as stated above.
