This study validated and developed a researcher-made instrument to evaluate the Positive and Resilient Leadership (PRL) practices of public-school leaders. The instrument was designed from an earlier qualitative study that elicited 50 public school teachers’ concepts of PRL from a metaphorical perspective. Using qualitative content and thematic analysis, five domains of PRL practices were identified, characterizing positive and resilient public-school leaders as providers of positivity, opportunity, wisdom, empathy, and reinforcement. These domains and their corresponding indicators formed the questionnaire for a quantitative study. The questionnaires were distributed to 500 participants in the five most populated public schools in Metro Manila. Confirmatory Factor Analysis (CFA) was used to ensure the reliability and validity of the measure of PRL constructs. Findings showed that providing wisdom obtained the highest mean at 5.33, while providing positivity got the lowest mean at 5.28. The reliability measures, factor loadings, and average variances extracted indicated that convergent validity was established in the five dimensions of PRL. Model fit indices indicated that the CFA model has a good fit with the data. Further, the CFA model revealed that all 10 indicators of each dimension of PRL have acceptable factor loadings that are all significant at p < 0.01.
