The study is also targeted at getting feedback from respondents on the way forward for the organisation in the area of study. This study looked at performance in eleven areas including the organisation’s mission, ethics and accountability, leadership and management, strategic planning, finance and technology. The research was centered on five divisions of the organisation. The main tools for data collection were questionnaires and interview. The conclusions drawn in the study are that the existing culture does not mirror the preferred culture; culture and performance have a mutually reciprocating relationship. The study showed that the current level of performance could be improved if support systems in the area of finance, staff and technology are put in place. Furthermore the organisation should encourage shared leadership and give credit to others when they do the right things. Staff need to be trained in information technology so they can be current in the use of the technology.Organizational cultureGhana Education Service (GES)OrganisationOrganisation performanceThesis
