This study aimed to evaluate the personality type of high school students (eighth, ninth and tenth) of some private educational institutions in the city of Ambato in Ecuador, through the Eysenck model, which is a recognized Personality test. The population of this research was made up of 287 students of both sexes, aged between 12 and 14 years. The Eysenck questionnaire evaluated the personality dimensions of these adolescents, which are differential organizations that shape the person’s interactions with various learning contexts and, in turn, their adaptation to the social environment. However, it is necessary to distinguish that the analysis of criterion “L“ corresponding to “Truthfulness“ required the exclusion of 80.84% (228) of the students that were initially evaluated, therefore, the results are based on 19, 52%, remaining 56 students. The aforementioned dimensions were: (i) introversion-extroversion; (ii) N=stability-instability; and finally, (iii) L= truthfulness. In the majority of the population analyzed, an ambivert range was distinguished, considered “age-specific”, this implies that students can be considered flexible people, who can be introverted and extroverted, depending on the social situation in which they find themselves.
