This study examines effective financial education teaching skills among a group of elementary school teachers using a specially designed composite financial literacy score. Data were collected via a 31-hour training program. The aggregate score considers financial self-efficacy, subjective financial knowledge, and financial behavior. We find that this score is correlated with net worth, personal finance training and teaching personal finance. In addition, our findings suggest a direct relationship between financial self-efficacy, subjective financial knowledge, and financial satisfaction with higher levels of positive financial behavior. These results contribute to a growing body of literature on financial knowledge since Puerto Rico is usually not included in this type of research in the U.S.
