The study ventured on producing a mathematical model between teachers’ grit of tertiary education teachers and licensure examination performance of teacher education institutions. Using the descriptive correlational design, the study sought the following variables: grit scales of the faculty; and the September 2017 Licensure Examination for Teachers results. Using the binary logistic regression, it was found out that teachers grit is a high predictor for the licensure performance of institution. A high grit scale will mean a great likelihood and high probability that the institution will perform above the national passing rate in the Licensure Examination for Teachers.
