This study examines the psychometric properties of a scale of daily stress in the school context (EECE). The factorial structure and internal consistency were studied in a sample of Chilean children and adolescents from the Maule region (n = 734) between 10 to 17 years old. The factorial structure of three factors was simple and coherent with the main dimensions of the school context that can become stressful for students: academic stress, relationship stress and inadequate school climate. The internal consistency was good for both the overall scale as well as for the three factors. Also, significant differences were found in the perception of stress according to sex (male / female) and geographic location (rural / urban). These findings are consistent with the existing literature.
