This study aimed to develop and evaluate the SEP–D–P–O–E–A school management model for Ban Siriphattana School by integrating the Sufficiency Economy Philosophy into five management processes: decision-making, planning, operation, evaluation, and adjustment. A Research and Development (R&D) approach combined with mixed methods was employed in four phases: situational analysis, model development, implementation, and evaluation. The participants consisted of 81 school stakeholders and 82 upper primary and lower secondary students selected through purposive sampling. Three research instruments were employed: (1) a school management questionnaire based
on the D–P–O–E–A framework, (2) a 40-item learning achievement test, and
(3) a satisfaction questionnaire. The instruments were validated through content validity assessment with Item-Objective Congruence (IOC) values ranging from 0.67 to 1.00 and demonstrated high reliability (KR-20 = 0.89). Data were analyzed using mean, standard deviation, and dependent t-test.
The findings indicated that the overall level of school management based on the D–P–O–E–A framework was high (Mean = 3.93), with the operation component receiving the highest rating. Student post-test scores (Mean = 44.692) were significantly higher than pre-test scores (Mean = 32.154) at the .05 level (t = 12.874, p < .001), demonstrating the effectiveness of the SEP–D–P–O–E–A model in improving learning achievement. The results suggest that integrating the Sufficiency Economy Philosophy with a systematic management cycle provides an effective and practical approach for enhancing student quality and can be applied in schools with similar contexts.
