The present study explores the impact of a training in neurocognitive insights on teachers’ stress. The authors found that the training had a significant impact on the stress experienced by teachers in their professional and personal functioning. The participants experienced less stress, more confidence and less impulsiveness. Furthermore, the participants showed a greater awareness of functioning, state of mind and stress, as well as clear prefrontal attitudes. The participants also mentioned changes within themselves and their professional environment. They indicated that teacher–student relationships were improved and unwanted or problematic students’ behavior was decreased.
