The improvement of public service delivery involves capacity building in public servants. Training programmes are one of the most popular capacity building approaches. The purpose of this study was to investigate the influence of these human capacity development programmes on public service delivery. The objectives of the study were to find out how training influence performance improvement in the public service. The research used descriptive research design with stratified random sampling to select the samples. The samples were picked through simple random sampling thus enabling all members of the target population to be represented. The target population comprised of 300 active members of the African Association for Public Administration and Management (AAPAM) and 20% of the target population formed the sample size. Questionnaires were used for data collection. The study found that training has a moderate positive influence on service delivery and this is attributed to effective training content and training methods. The study recommends adoption of proactive human capacity development strategies and incorporation of technology to enhance their positive influence on service delivery and mitigate on the negative influence to ensure efficient services are offered to the citizens.
