Abstract
The process of public assurance is a sequence of stages, following which you can obtain the right to use it, the service or the work, as a result of the award of a public procurement contract. The contracting authority carries out in the framework of the public insurance process various ways of awarding public service contracts in order to award contracts for products, services or works. On choosing the course of the process to make public, the contracting authority uses those qualification and/or selection criteria as well as award criteria, at different moments of the process. Most of the time in the development of the ways of assigning the specifics of the domain and the public ones, even specialists “impede” the understanding of three categories of previously mentioned criteria, and that is why it is necessary, on the one hand, to clarify the concepts of qualification criteria and/or of selection. and award criteria, and on the other hand it is necessary to identify the moment in which they are applied but also the way in which they are applied in this way depending on the method of award assumed by the contracting authority.
