Aqel , Yaser A. Alshorafa,Youssef M. Abu Amuna, Alkurd A. Mohamed Abstract: The study aimed to identify the effect of return on investment evaluation for training on job performance conducted by a case study on Islamic University of Gaza, Palestine. To achieve the objectives of the study, the researchers used the questionnaire as a main tool to collect data, and the descriptive and analytical approach to conducting the study. The study population consisted of (892) employees working at IUG, Palestine. The researchers used the stratified random sample method and the multiple regression method to measure the effect. The study tool was distributed on the sample (263). Further interviews were conducted with high level management. The results of the study showed that there is an exploitation of the university's resources in training and qualifying employees through holding specialized programs and courses implemented by the specialized authorities at the university, with an average direct relationship between the evaluation of the return on investment in training and job performance. Training also contributes to the acquisition of new skills by the employees and the increase in knowledge outcomes of the employees that qualify them in the job they work for. The study recommended the necessity of working on holding more training programs that are suitable for the employee's time frame to facilitate their enrollment, and selecting work-related programs to develop their skills and solve problems facing them during work while developing these programs to enhance the culture of knowledge exchange between workers at the same job level. Also the study recommended adopting accountability policies for employees with low job performance and setting standards that motivate them.
