By means of this annual report we present the overall work of the Secretariat, the Executive Committee, and the various networks and delegations of the Association during 2016; a work that would not be possible without the support and complicity of the ensemble of member cities. With this internal and external instrument of communication, we aim to explain the progress made, while at the same time we encourage new cities to join forces in such an important task as is the improvement of the quality of life in the cities through education.
