Lecturers are the individuals employed by the higher educational institutions to educate students based on their competency. The roles of lecturers are not limited to the education of students only but also required to do the activities related to the research and the service for the community. These three aspects are considered to be the measure of lecturers’ performance. Consequently, the institutions must focus on the factors behind the performance of their lecturers to increase performance. By denoting the evidence of the previous study, the three determinants of performance are identified, namely, motivation, emotional and spiritual intelligence. Therefore, this study attempts to examine and analyze these determinants by the private university lecturers becoming active members of the Indonesia Management Forum. To take the samples and collect the data, we utilize a simple random sampling and survey method. Also, we use a variance-based structural equation as the model to analyze the attained data. Overall, this study concludes that there is a positive effect of emotional intelligence on the performance of lecturers. On the other hand, the effect of motivation and spiritual intelligence is not confirmed.
