Cryptologic Technicians Interpretive are the Navy's linguists. CTIs attend language training at the Defense Language Institute (DLI), in Monterey, California. They specialize in the analysis of foreign language materials and the preparation of statistical studies and technical reports. Language training is open to men and women in Arabic, Chinese, Korean, Persian-Farsi, Russian, and Spanish. Additional languages are available to CTIs that qualify for an additional language. A Defense Language Aptitude Battery (DLAB) score of 100 or better is required. Language assignment is determined at DLI based on aptitude, school quotas, and Navy requirements.

At times they are closely supervised but often work independently or in small, coordinated teams. Their work is of high interest to command and decision-making levels. It is mostly mental, involving foreign language materials.
