This study investigates the effect of training on employee performance, the case of commercial banks in Klang Valley focusing on variables such as training design, on the job training, off the job training, and employee performance. The study utilized a convenience sampling technique involving 480 respondents, revealing an employee that is predominantly young (65.2% aged 25-29), male (57.7%), and highly educated (90.6% hold a degree). The majority earn between RM 1500 and RM 3000, indicating a lower income bracket, and most have moderate experience, with 69.0% having 3-4 years of employment. Reliability analysis indicates strong internal consistency across all constructs, with Cronbach’s Alpha values ranging from 0.725 to 0.896. Correlation analysis reveals significant relationships between training variables and employee performance, with on-the-job training showing the strongest correlation (0.814). Multiple regression analysis further supports these findings, indicating that training design and on the job training are significant positive predictors of employee performance, while off the job training has a slight negative association. The results underscore the importance of tailored training strategies to enhance employee performance, particularly in a young and educated workforce. The high statistical significance of these findings suggests that effective training is crucial for improving performance in the banking sector, emphasizing the need for ongoing investment in training and development programs and offering valuable recommendations for commercial banks to refine their human resource development strategies.
