The CTBTO offers  a limited number of unpaid internships every year.  Interns usually work on specific assignments. Opportunities for internships are available subject to the current needs of the individual Divisions within the CTBTO.

Internships should not be shorter than three months and not longer than six months on a full-time basis.  As the CTBTO cannot provide financial support for interns, all successful applicants are expected to make their own arrangements for travel, lodging, living expenses and insurance during the internship period.

Interested candidates who are under 30 years of age and are studying towards a university degree, or have already received a degree, should complete a Personal History Form accompanied by a letter of interest.  Applications are accepted on an on going basis.
