This study examined the influence of employee training and development on organizational competitiveness in selected Commercial banks in Lokoja, Kogi State. The primary objective was to assess how mentorship and coaching programmes, and career development opportunities affect the competitive performance of Commercial banks. The research adopted a descriptive survey design to collect data from employees of four major Commercial banks: First Bank Nigeria Plc, UBA, Access Bank Plc, and Zenith Bank Nigeria Plc. The total population comprised 172 employees, from which a sample size of 120 was determined using Taro Yamane’s formula. Out of the 120 distributed questionnaires, 103 were returned, representing a 85.83% response rate. Data were collected through a self-administered structured questionnaire and analyzed using descriptive statistics, including means and standard deviations, and inferential statistics of multiple regression analysis to test the hypotheses. The findings revealed that mentorship and coaching programmes (β = 0.29, p < 0.05) and career development opportunities (β = 0.31, p < 0.01) all had a significant positive impact on organizational competitiveness. The study concluded that robust employee training and development initiatives substantially enhance the competitive edge of Commercial banks. It therefore recommends that banking institutions should institutionalize frequent and diverse training programmes, develop structured mentorship and coaching schemes, and provide clear career advancement opportunities to foster employee growth and organizational success.
