Global General Service Test (GGST)

Test Format

The GGST is a computer-based online assessment, administered in a proctored environment at United Nations Headquarters and Offices Away from Headquarters. The GGST assesses job-relevant abilities and core competencies through work-relevant scenarios and tasks.

There are three sections, each of which assesses a candidate’s ability to deal with a particular aspect of typical GS-related tasks:

  1. The verbal reasoning section, which assesses a candidate’s ability to work effectively with written communication such as reports and emails;
  2. The numerical reasoning section, which assesses a candidate’s ability to deal effectively with numerical data presented in the form charts and tables; and
  3. The situational judgment section, which assesses a candidate’s ability to deal with work-related scenarios in accordance with the UN Core values and Competencies.

Exam preparation

The GGST is a general ability test; therefore, no preparation is needed. However, you may find it helpful to do the following for each test part prior to your test:

Verbal Reasoning Numerical Reasoning Situational Judgment
Practice reading in the language in which you are going to take the test for the Verbal Reasoning section. Practice basic arithmetic skills such as calculating percentages and changes in percentages. Familiarise yourself with the United Nations Core Values and Competencies Framework.
