Over the past few years there has been an increasing use of informatics means in the school, as an essential mechanism to make the much desired change and modernization. However, this not translated into a simplification of administrative procedures.

The set of data produced will support the necessary information to external evaluation of institutions. The application was developed considering as a case study the Arronches Group of Schools, which is currently implementing what Improvement Action Plan, among other things, aims to improve the levels of success to Portuguese and Mathematics disciplines.
