Using a quantitative evaluative approach, a purposive sampling method was employed to select 97 participants. A questionnaire measuring indicators of noble character—such as integrity, responsibility, honesty, and social concern—was developed based on a Likert scale of 1–5. Data were collected both online and in-person, ensuring respondent comprehension. The validity and reliability of the instrument were assessed through Confirmatory Factor Analysis (CFA) and Cronbach's Alpha. Results revealed that most items scored below a mean of 2, indicating a prevalent disagreement among respondents regarding the character values assessed. High outer loadings for social concern and responsibility indicators confirm the instrument's effectiveness. In conclusion, the holistic learning model significantly influences the development of noble character, underscoring the necessity for robust measurement tools in educational settings.Keywords: Validity, realibility, intrument, character, holistic]]>
