Abstract: Despite overwhelming theoretical propositions that organizational learning is strong positive determinant of competitive advantage, little empirical work exists to substantiate these theoretical suggestions.The few empirical studies available have not shown the role that learning performance plays in the attainment of competitive advantage. The relative absence of empirical research does not persuade leaders, managers and employees to adopt learning initiatives or measure learning performance.This study examined the mediating role of learning performance learning in the relationship between learning processes and competitive advantage amongstate corporations in Kenya.The study employed a descriptive, cross-sectional research designand used both quantitative and qualitative methods to gather data from 198 staff from 35 state corporations comprising of senior managers, middle manager and non-management staff.
