Development of a Teacher Grit Scale (TGS): Predicting the Performance of Educators in the Philippines

The study aims to develop and validate a Teacher Grit Scale and determine its predictive validity for performance. This quantitative research utilized exploratory, confirmatory, and regression analyses based on data from 1425 teachers of the Department of Education, Philippines. Exploratory factor analysis established the factorial validity of a 2-factor structure as compared to 3-factor and 4-factor models. Confirmatory factor analyses from Region IX and Region X of the Department of Education reveal strong cross-validation between the 2-factor models and the data using goodness-of-fit indices. These outcomes show that the factors describing grit are: (1) Perseverance in Teaching and (2) Passion and Purpose in Teaching. Grit relates significantly to teacher performance. However, only the first dimension of grit - perseverance in teaching, established predictive validity with performance.
