This study primarily sought empirical results to be used for a more complicated future research undertaking. This study categorized the students of the College of Teacher Education according to their left, right, or confluent brain hemispheric orientation through a preference scale. Also, these college students were classified with respect to their low, average, or high level of Mathematics performance basing from the grades in Mathematics subjects. Diversity in college students‘ gender, age, and ethnicity were analysed for their effect on the brain hemispheric orientation as well as their effect on their level of Mathematics performance. Likewise, this study investigated the influence of brain hemispheric orientation on the level of Mathematics performance of the college students. Findings revealed that there were significantly more left-brained than the combined number of right-brained and confluent-brained college students. There was numerically more college students who had average level than their counterparts with low level and high level of Mathematics performance. Results indicated that female college students outnumbered their male counterparts. The college students belonged to age range 16 to 34 years while 86% belonged to age bracket 16-21 years. The Visayan-college students dominated the student population. There were: significantly more female college students who were left-brained than their male counterparts; significantly more college students at age bracket (16-21) young who were leftbrained than their counterparts in other age brackets; significantly more Visayans were left-brained than their counterparts in other ethnic groups. More female college students had high and average level of Mathematics performance than their male counterparts but the numerical difference did not show significant results. There were significantly more college students at age bracket 16-21 years with average level and low level of mathematics performance than their counterparts in other age brackets. More Visayan college students had average level and low level of mathematics performance and which outnumbered their counterparts in other ethnic groups. Gender was found to have not significantly affected the level of Mathematics performance but age, and ethnicity did significantly affect the level of Mathematics performance. Results revealed that brain hemispheric orientation of college students significantly explained their level of Mathematics performance.
