Modern trends in educational technology have evidenced the increasing importance of mobile devices in language learning. The need of sophisticated devices that can facilitate lifelong learning wherever the students might be. Facilitating learning, however, implies that students have to be assessed through the same delivery models that are used in their learning mode. Mobile devices are commonly used to learn languages through mobile phones, iPads and Tablet PC's. However, testing methods remain the same as in the last 40 years. In most cases, computer based test tasks resemble too much to those used in pen and paper. This paper shows a pilot study done at the Universidad de Alcala (Madrid-Spain) with tablet PC's indicating its strong aspects as well as its weaknesses. The study concludes that more research is necessary to implement such convenient method of test delivery.
