This research addresses the change in how the Spanish University Entrance Examination can be delivered in the future. There is a wide acknowledgement that computer tests are very demanding for the delivering institutions which makes computer language testing difficult to implement. However, the use of tablet PCs can facilitate the delivery at even lower cost than the regular computer based language testing. 183 students in their last year of high school took a computer based language test which included reading, writing, listening and speaking. The research aspects were 1) whether they feel at ease with the tablet PC exam; 2) if they felt that visual aspects were accessible and 3) whether the interface organization was clear. The paper first has a brief description of the OPENPAU® platform, after it addresses the field study based on questionnaires and observations with students during the test delivery, finally the results indicate that this means of language test delivery could be adequate not only for the Spanish University Entrance Examination but for most standardized tests.
