The purpose of the study is to assess the impact of Training and Development (T & D) on the performance of employees in the Judicial Service. The study concentrates primarily on the employees of the Kumasi High Courts. The study was guided by three (3) objectives which were to find out if there are any T & D programmes for employees in the Judicial Service, Kumasi, to find out the relationship between T and D in the Judicial Service, Kumasi and finally to assess the impact of T and D on the performance of employees in the Judicial Service in Kumasi. The study was a descriptive survey with a sample of seventy (70) respondents from different sections in the High Court, Kumasi. The researcher collected data using a questionnaire that was self-generated from literature in the area of T & D. The researcher analysed the data by using descriptive statistics such as percentages and frequencies and also used regression and correlation analysis from the SPSS. The results of the study showed that there was an existence of T & D programmes in the Judicial service, also there was a positive significant correlation between training and development and finally, the results showed that training and development were significantly related to performance. It was, therefore, recommended that: identification of training needs should be done more professionally and more often in conjunction with the line manager, as well as with the individuals involved; and also a wellstructured training calendar be created for use at the Judicial Service at stated periods of time.
