This master's thesis describes the characteristics of IPA instruments and all five components covered by the IPA instruments. The desire of countries to engage in a large family of European Union member states requires certain adjustments for each country individually. All countries do not have the same conditions, opportunities, or resources, so they can't all be placed in the same point of observation. For this reason, yearly allocated fundswere analyzed within all components,trends and differences that took place over observed time. Observing only allocation of funds, year 2010. was a turning point. From 2011., funds grew rapidly, and the best example of that growth was Turkey, which gained of 2 billion EUR for all five components combined.In analyzing resource utilization it's visible that there were some problems present regarding funds redrawal. Also, usability of allocated funds was at a pretty low level. Positive indicatorwas that the countries, potential cadidates, were active for a large part of the period in which the IPA instrument was used. They used funds better even than theEuropean Union candidate countries. It is also a fact that Croatia, Turkey and Macedonia did their job badly, especially by 2010, so it was not difficult for other countries to be a step ahead of them. At the end of the thesis, selected positive examples from the IPA instrument were described. They brought a certain benefits to their beneficiaries, like growth, higher employment rate, environmental protection, human rights protection and international cooperation between countries.
