Administrative capacities constitute a very important component for the functioning of public administration in all countries, especially for those that are in the process of European integration. In this regard, countries are obliged to undertake various political, legislative, organizational and educational measures in order to increase the administration's capacities. Most of the countries that are undergoing the European integration process are developing administrative reforms, with particular emphasis on administrative capacity building in order to meet European criteria and standards for a functional, responsible, efficient and effective administration. To achieve these objectives, the EU has foreseen principles, rules, standards and criteria which are mandatory for each country aiming for EU membership. These objectives are realized through various measures, actions and strategies for the training of the administration in order to achieve approximate results in the implementation of principles, criteria and standards, as in the EU member states, known under the term acquis communautaire.
