The main purpose of the present investigation was to develop a model for personnel administration of Souphanouvong University, Lao PDR. To achieve the objective, a mixed method research was employed and the study was divided into four phases. Phase 1 examined the current status of personnel administration. Regarding this phase, a document analysis was conducted and the survey questionnaires were administered to the sample group. The population for this phase was administrators and teahers who worked at the university in total of 415 people. The sample group was 324 participants who were selected by using a purposive sampling method. Phase 2 developed a personnel administration model by using a Dephi Technique. The questionnaire was used in this phase. The target group consisted of 19 experts who had experience in the area of personnel administratioin. Phase 3 evaluated the model of personnel administration in terms of feasibility, utility, propriety, and accuracy. The target group was 9 experts. The data were collected by using focus group discussion. Phase 4 confirmed the potential practice of the model. The target group for this phase was the administrators, staff, and teachers in total of 60 participants. The tool was the 5-Likert scale questionnaire and the data were computed to find mean and standard deviation. The findings are as follows. The current status of personnel administration was at a high level, meaning that the practice of personnel administration is appropriate. Also, the development of the personnel administration model consisted of seven components such as planning, selecting, managing, developing, rewarding, evaluating, and retiring. The evaluation of the model in terms of its feasibility, utility, propriety, and accuracy was at the high level. Finally, the results reveal that the model was confirmed as the high potential for application/practiced. This research illustrates a signficant knowledge for personnel administration in the context of Laos and beyond. It is suggested that the concerned university administrators consider implementing it and revising its policy.
