The GTCI is a composite index, relying on a simple but robust Input-Output model, composed of six pillars, four on the Input side and two on the Output side. The GTCI generates three main indices that are the most visible focus for analysis, namely:
1. The talent competitiveness Input sub-index, which is composed of four pillars describing the policies, resources, and efforts that a particular country can harness to foster its talent competitiveness. Enable (Pillar 1) reflects the extent to which the regulatory, market, and business environments create a favourable climate for talent to develop and thrive. The other three pillars describe the three levers of talent competitiveness, which focus respectively on what countries are doing to Attract (Pillar 2), Grow (Pillar 3), and Retain (Pillar 4) talent. The Input sub-index is the simple arithmetic average of the scores registered on these four pillars.
2. The talent competitiveness Output sub-index, which aims to describe and measure the quality of talent in a country that results from the above policies, resources, and efforts. It is composed of two pillars, describing the current situation of a particular country in terms of Vocational and Technical Skills (Pillar 5) and Global Knowledge Skills (Pillar 6). The Output sub-index is the simple arithmetic average of the scores obtained on these two pillars.
3. The Global Talent Competitiveness Index (GTCI), which is computed as the simple arithmetic average of the scores registered on each of the six pillars described above.
