Abstract: This study sought to investigate the influence of intellectual stimulation training on graduate’s performance focused on the Pan Africa Christian University (PAC) Transformational Church Leadership (TCL) diploma program graduates of 2016 and 2017, in selected churches in Kenya. The study sought to establish the extent to which TCL trained graduates/church leaders in intellectual stimulation influence the church leader’s performance. Survey and interviews were used to collect quantitative, and qualitative data. The study found leader’s intellectual stimulation to have a strong positive and significant correlation with church leader’s performance among graduates, with a Pearson correlation of 0.570, while in church members/congregation had a Pearson correlation of 0.69. The study revealed that church leader’s intellectual stimulation made them more creative and innovative in decision-making and conflict resolution which significantly influenced church growth. The study concluded that intellectual stimulation positively and significantly increased performance in church leaders in Kenya.
