The present article reveals the procedure carried out by the authors in the design and elaboration of the survey questionnaire applied to the students as measuring instrument for the diagnosis of the undergraduate training process, all of which arises from the research project "Pedagogical model according to the demands of the 21st century for the training of professionals at the University of Artemisa”. The procedures granting validity and reliability to the measurement instrument were also considered and presented as well as the statistical analysis evaluating the internal consistency of the questionnaire as result of the application of the Multidimensional Correlation Coefficient rpj, a novel and recognized logical procedure accepted by the Classical Theory of Tests. The piloting was done to an intentional sample of 13 students of the Foreign Languages majoring at the School of Sciences of the Education for constituting a homogenous group with an appropriate motivation by their studies. When applying the coefficient to the results that were registered in each one of the questions of the instrument, oscillating values between 0.58 and 0.64 were obtained, which implies that the instrument has consistency and, therefore, it is reliable.
