Technological advances pose challenges for teachers at different educational levels, where the application of ICT strategies requires training and strengthening of digital skills, so it is essential to constantly update teachers to improve teaching in the long term. Thus, the objective of this research is to identify the areas of improvement regarding the digital competencies of educators for the optimization of their teaching practices through a training program mediated by ICT. Regarding the applied methodology, it was carried out under a sample of 27 secondary education teachers by means of a descriptive non-experimental design through a complementary mixed method that was developed in four phases: a) characterization of the digital competencies of the trainers. B) design of the strategy and training in digital competencies. C) implementation of the training strategy. And d) evaluation of the strategy. Among the findings, 74% of the sample reached satisfactory levels with respect to the training program, affirming that training in digital competencies, based on instructional design and evaluation models, achieves positive results, presenting a significant improvement in the digital competencies of teachers.
