This study examined student academic optimism in four diverse North Texas school districts. This study used a convergent parallel mixed methods design to analyze results of an online administration of the survey, and Latinx student responses to a focus group protocol derived from the survey. Quantitative results indicate the individual scales making up the construct align with previous research results. The three scales were found to be strongly and significantly correlated, indicating the potential for validation. Qualitative results indicate Latinx students' perceptions of their academic careers align with four themes. Latinx students are keenly aware of their teachers as a person, their school as a community, the intrusion of the outside world, and students as agents. Qualitative results support the importance of the three components of the construct, student trust in teachers, student academic press, and student identification with school. As a new source of data, combined with existing metrics of instructional effectiveness, student academic optimism could increase the ability of decision makers to improve the overall efficacy of school systems especially when addressing the persistent opportunity gaps for Latinx and other students of color.
