This research presents three possible models of introducing and disseminating electronic school administration systems, which are 1. the purely market model, 2. the centralized model and 3. the quasi-market model. In Hungary the quasi-market model was used between 2005 and 2010. This paper shows the advantages and contra productive effects of this dissemination model that had been used. These latter include that certain operators could get competitive advantage during the tendering. Accreditation processes did not take place annually, thus real competition had ceased, and one service provider got into a dominant position. Contracts had been signed by the maintaining bodies of the schools – local governments – which meant that besides professional priorities, other interests could have been taken into consideration as well. No public forum was developed for the administration services, although it could have strengthened the competition. While introducing the accredited electronic school administration systems, no specific target values were laid down and capacity utilization could not be monitored. Thus pricings used by companies and actual costs were not transparent enough for the state that paid for it all. The financing state did not control the processes according to the standards of the services and the volume of usage. Schools did not develop an owner’s attitude towards the product that was bought positively from the information technological financial framework by the maintaining bodies. So in many schools, they simply did not use the service, although it had been paid. The framework that could be spent on the accreditation systems was changed from year to year, which caused an insecure financial environment for the service providers. This made it difficult for them to carry out their tasks and to plan long-term developments. Data shows that in order to successfully introduce electronic school administration systems, there is a need to use a more effective dissemination model than the quasi-market one that was tested between 2005 and 2010.
