U.S. Foreign Service Officer Test (FSOT) 2026–2027: Eligibility Requirements, Registration Deadlines, Exam Dates, and How to Apply

Overview

The Foreign Service Officer Test serves as a component of the selection process for individuals seeking to become Foreign Service Officers with the United States Department of State. The examination forms part of a recruitment process designed to assess candidates interested in representing the United States abroad, supporting American foreign policy objectives, and contributing to diplomatic relations. The test is administered through Pearson Professional Assessments, which provides information about registration, scheduling, test centres, online proctored testing, accommodations, and score reports. Candidates can take the examination at participating domestic and overseas testing locations, or through at-home online proctored testing via Pearson's OnVUE platform.

Taking the examination does not guarantee employment or appointment as a Foreign Service Officer. Candidates must satisfy the eligibility requirements and follow the Department of State's wider selection procedures. Applicants are encouraged to use a personal email address accessible consistently throughout the hiring process.
