Global General Service Test (GGST)

The GGST is a computer-based, proctored global test, which has replaced the Administrative Services Assessment Test (ASAT) in 15 July 2014. It is an entry level assessment requirement for recruiting into the positions in the General Service (GS) category. The GGST assesses job-relevant abilities and core competencies of the long-listed applicants for GS positions, through work-relevant scenarios and tasks, in an efficient, effective, and fair manner.

Built by the Examinations and Tests Section, Office of Human Resources Management, the GGST serves to address a Staff Management Coordination Committee (SMCC) request to create a global General Services test that is consistent across the organization. It was developed based on in-depth job analysis of the core functions in the GS and related categories, Hiring Manager (HM) interviews, and a review of the latest research in selection testing and was pilot-tested with the participation of the staff members across duty stations before it was officially rolled out at United Nations Headquarters and Offices Away from Headquarters.

The test is required for candidates applying for GS positions at all levels (1-7) without a valid ASAT/GGST score, with the exception of certain functions (e.g., Security Officers, Nurses, Gardeners, and Trades and Crafts), for which the existing appropriate tests will be given.

Applicants interested in working for the United Nations in the General Services category, must first apply for a vacant position advertised on this website. Once your application has been reviewed, if you meet the requirements, you will be invited to participate in the GGST at the duty station in which you have applied for a GS position.

Smiley face Candidates applying for General Service category positions are expected to have fulfilled the minimum requirements below:
  • Having a high school diploma or equivalent
  • Being at least 18 years old
  • Having the minimum required work experience relevant to the job and its level
  • Meeting the language requirements for the job. Most jobs require fluency in one of the two working languages, English or French.
  • Successfully passing the Global General Service Test (GGST) or the Administrative Support Assessment Test (ASAT) and any specialised test required for specific functions. These tests are administered at the local duty station where you wish to apply.
  • There might be additional requirements which are listed in the specific job opening. Always check to make sure you meet the minimum requirements for the job for which you are applying.
