This document presents research on determining the personality types of students in the ARID AGRICULTURE (EVENING-BSIT-4) program and whether personality impacts class participation. The objectives are to see if personality contributes to low participation, if ambiverts exist, and the ratio of ambiverts. A questionnaire was administered to a sample of 14 less participatory students. The results and conclusion indicate that personality likely influences participation, ambiverts are rare, and teachers should employ strategies to engage introverts.
