Due to the rapid development of methods and technologies in many fields, especially regarding subjects of sustainable engineering, vocational qualification is not finished with basic education. Measures of advanced training have to be chosen adapted to the individual demand, in order to allow for an efficient achievement of required additional competences. But for most interested persons, it is very difficult to find courses suitable for their specific learning aims as well as for their individual state of existing competences. Based on the analysis of possible methods of training, an assistance system is being developed which enables the definition of a training schedule optimized toward the individual demand. For the topical example of manufacturing metrology, a competence net has been defined. Concept and method of the system can easily be adapted to other topics based on the proposed methodology. To prepare the proper application of Life Long Learning, adequate constraints have been established, regarding already basic education.
