This study aimed to analyse the factual models of national character values, establish a hypothetical model, test the feasibility and describe the determinants of character development and multicultural education based on local wisdom. This research was conducted with a research and development approach. The subjects of this research consisted of students, principals and teachers, while additional information came from various documents and events. The data were collected in numerous ways, namely by observation, interview, documentation, focus group discussion and intake from practitioners and experts, as well as questionnaires. The data analysis was held interactively as the compiled data were assorted. The results of the study showed that the factual models of the national character values development was carried out by integrating the characters in the subjects based on the learning implementation plan, the implementation of which is reflected in the functions of planning, implementation and evaluation. The feasibility of the national character development model and multicultural education based on local wisdom needs to be handled in a neat manner by planning, organising, implementing and supervising them properly. The determinant of character development needs to be assessed by focusing on the content, direction, goals, functions and principles of multicultural education, as well as on the functions and benefits of local wisdom through the input--process--output system approach.
