This paper describes ongoing work on the choice of modal expressions in the generation of recom- mendations about courses of study within the B.A.- program of the Ruhr-Universität Bochum. We fo- cus our work on the German modal verbs müssen (must), können (can), the subjunctive form sollte (should), and dürfen (may). The idea is to combine insights from formal semantics into the meaning of modal verbs with requirements for their choice in NLG-systems in order to achieve a linguistically satisfying model of their choice. The overall model is implemented in the CAN-system that plans courses of study and generates recommendations about them.
