Within this panorama, with this study the authors pursue to determine which dimensions of teacher well-being are capable of predicting the professional success of 88 pre-service primary education teachers who specialize in a foreign language so that they can be addressed in the training process.

Multiple linear regression revealed that of all the variables studied for teacher well-being (intrinsic motivation, expectations about good professional performance, professional distress, professional exhaustion, irrational beliefs, emotional intelligence and burnout) only emotional intelligence and intrinsic motivation have the ability to predict the success of teachers in training in their future professional performance. This result is of paramount importance for reconsidering the training that teachers receive during their university stage, which currently and substantially prioritizes the cognitive component over psychosocial and emotional components.
