Siette emerged back in 1998 as a final degree project carried out by Antonia Rios and directed by Jose Luis Pérez de la Cruz and Ricardo Conejo, with the idea to automate the performance of assessment tests at the University of Malaga. The first version was implemented in C using cgi technology.

Shortly afterwards, it was applied to the generation of questions from a database of European trees within the framework of the project TREE, and the evaluation of knowledge on agrarian economics in the framework of the European projects RITA and TEA.

Subsequently, a second version is implemented, this time in Java with JSP technology, which is used as an independent evaluation system within the framework of the LeActiveMath project. A first editor is built, called TEDI.

Parallel to technological development, new, more efficient and complete ways of dealing with the evaluation problem are being studied within the framework of intelligent tutor systems and open user models. These investigations culminate in the development of the tesis doctoral of Eduardo Guzman and later the tesis of Jaime Gálvez.

Within the framework of various projects subsidized by the National Research Plan and the Andalusian Research Plan, a third version in Java continues to be developed, which includes a new authoring tool, called ATHOS.

At this time (2009) the first plug-in was implemented to link with version 1.7 of Moodle and a protocol based on that allows communication with Siette through web services was developed. Since this date Siette has joined the Virtual Campus of the Malaga University. Later the plug-in was modified to support versions 2.x and 3.x

Various improvements in the interface and a multitude of new functionalities have been incorporated into Siette throughout all these years with the idea of ​​bringing all of them together in the same system in a way that she used frequently.
