Special education students continue to underperform as compared to their general education peers. The purpose and the research question of this study explored to what extent there is a statistically significant correlation among the personality traits of Psychoticism, Extraversion, and Neuroticism exclusively, and to what extent is there a gender correlation within each personality trait among the teachers working in special education classrooms. This research study was built upon the underpinnings of Eysenck's PEN Model. This biological theory focuses on three factors of personality, Psychoticism, Extraversion, and Neuroticism. Data were collected from 115 special education teachers working in a public-school district in southwest Florida. The personality trait variables were measured by the Eysenck's Personality Profiler-S and analyzed using a point-biserial correlation test. The data for the research question resulted in two correlations within the personality traits. The correlation value for Psychoticism and Extraversion was 0.210 with a significance of 0.024. Extraversion was positively correlated with Psychoticism and negatively correlated with Neuroticism. The results of the correlation test showed a value of -0.516 for Extraversion and Neuroticism, with a significance of 0.00. There was also a significant positive correlation specifically between males and the trait of Psychoticism. The results of the correlation test showed a value of -0.293 for Psychoticism, with a significance of 0.001. These findings contributed knowledge in the field of special education to serve as a foundation of teacher personality for future studies to be able to research comparisons and causation in this content area.
