The Eastern Partnership Index 2023 (hereinafter the EaP Index or the Index) is a unique data driven civil society produced monitoring tool that charts developments in the six Eastern Partnership countries towards democracy, good governance and rule of law, policy convergence with the EU and sustainable development. The Index’ rationale is to identify change in the six Eastern Partnership countries (Armenia, Azerbaijan, Belarus, Georgia, the Republic of Moldova, and Ukraine). As in the previous Eastern Partnership Index editions, the concept of ‘Approximation’ is used to monitor how far Eastern Partnership states are moving closer to or shifting away from the European Union.
