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:
- The verbal reasoning section, which assesses a candidate’s ability to work effectively with written communication such as
reports and emails;
- The numerical reasoning section, which assesses a candidate’s ability to deal effectively with numerical data presented in the
form charts and tables; and
- 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.
