Low job satisfaction and low motivation does not only reduce performance of the health systems but also constitute a serious push factor for migration of health workers, both from rural areas to the cities, and to other countries. It is therefore an important goal of human resources management in the health sector to strengthen the performance of health workers, from heads of health facilities to auxiliary staff. The general objective of this study was to assess the effect of the training on the performance of staff in the public health institutions in Kenya. The target population is the doctors, clinical officers, nurses and subordinate staff serving in public health facilities within Siaya County. The data was collected through administration of questionnaires. The questionnaires included both open ended and closed questions. The researcher took a sample size of 20% giving a sample size of 56 respondents, employing a stratified sampling technique. The researcher distributed the questionnaires and collected them after two weeks which was sufficient for the respondents to have filled them adequately and duly. Then the data was then entered by coding into a computer program, SPSS to facilitate analysis. From our study it shows there is a strong positive relationship between training of employees and performance.
