Keeping an e-learning system alive consists not only in developing and installing it, but also in maintaining the system updated, improving its features and adding new ones. Hezinet is a commercial e-learning system for Basque language learning that is being used since 2000 in more than 60 Basque-adult schools. In this period, although the good results achieved, authors have realized the necessity of some improvements and new features. This paper introduces three new components of Hezinet as a way to present some key issues in the development of a successful e-learning tool: a computer adaptive admission test generator, an on-line calibration supporting component, and an item/test authoring tool.
