This is research aimed to construct and validate an instrument to assess educational performance of students in initial training from the graduates standards defined by the Ministerio de Educacion de Chile (2011). The validation was developed from expert opinion based on the procedure proposed by the authors Rovinelli and Hambleton (1977). Later, the instrument was applied to a sample of 58 students of Basic Pedagogy at the Universidad Catolica del Maule (Chile), in order to determine its internal consistency. The results showed acceptable values in the index of consistency and correspondence factor, since all are located on the index 0.40. The internal consistency index averaged a total of 0.98. The results show that the instrument presents adequate psychometric characteristics, regarding the validity of content through expert people and the internal consistency through the Alfa of Cronbach.
