Assessment is a key element in any course, and providing students with a balance between formative and summative assessments is crucial. Defining such a process is a complex task for teachers and often entails a great workload. This makes it necessary to have tools to help in the assessment process definition and its monitoring. This paper first analyses the possibility of using the available tools in Moodle. For that, we carried out a bibliographical study, conducted semi-structured interviews with 26 teachers, and analysed the use of the Moodle gradebook in their courses. We found that teachers find it quite difficult to use the Moodle gradebook, so they rarely take advantage of all its possibilities. Taking this into account, we present Forge, a system that facilitates the definition of assessment processes following the e2Forja methodology in such a way that the produced process can be exported to Moodle. We have analysed whether Forge makes the assessment definition process easier or not. We have selected four courses to carry out a case study using Forge and interviewed the teachers again. We detected that Forge facilitates the assessment process definition and its monitoring, taking advantage of the characteristics of the Moodle gradebook.
