Cryptologic Technician Maintenance (CTM)

What We Do

Assisting in electronic system installation, configuration and modification;
Repairing and calibrating a wide variety of precision electronic test equipment;
Qualifications and Interests

ASVAB standard is MK+EI+GS+AR=223

CTM’s must learn advanced electronic system trouble- shooting methods based on complicated technical concepts. They must be resourceful, logical and possess an average degree of manual dexterity and be of exceptional character. Applicants must be U.S. citizens and meet eligibility requirements for continuous access to Sensitive Compartmented Information (SCI). Eligibility for a Top Secret clearance is determined by the results of a Single Scope Background Investigation followed by a reinvestigation every five years. Normal color perception and normal hearing are required.

Working Environment

CTM's are assigned to electronic maintenance departments and divisions. They may be assigned to either day work or shift work in a large maintenance facility or one of the individual or two-person independent duty assignments at sea or ashore.

Maintenance departments are usually divided into specialized maintenance shops and are normally air-conditioned, well-lighted and completely equipped.


The CTM rating is divided into two major career-training communities: fleet cryptologic/direct support systems and signals collection systems. Duty assignments are determined by the CTM's qualifications, past duty history and available vacancies.

Opportunities for formal training in advanced computer-based systems are provided for about 90 percent of all CTM assignments. More than 1,500 men and women work in this rating.
