This book presents the results of the research “Limits and possibilities of the diagnostic-formative teacher evaluation experience (ECDF) in its articulation with training”, developed by Olga Cecilia Díaz Flórez and Luis Fernando Marín Ardila. This was aimed at understanding how the articulation between the formulation and execution of the policy was generated, based on the identification and analysis of achievements; but also, at recognizing the limits of this experience in terms of the role it plays in the qualification of the training process, particularly of educational and pedagogical practices. Here we ask, in particular, about the limits in terms of whether these are given by the conception, the implementation or the pragmatics linked to the use of evaluation, or by the distancing between conception and implementation, among others. In this sense, the limits and possibilities of this public policy are understood.
