The Civil Service Agency was established in 1973 by an Act of the Legislature to increase efficiency in the civil service and also act as the central personnel agency of MACs.

The CSA is independent from all other Ministries and Agencies of Government and serves as the central government agency responsible for managing the Civil Service. It is responsible for improving the human resources, service delivery, effectiveness, and efficiency of the Service, which entails planning human capacity needs, recruitment and selection, training and development, performance management, and career development of civil servants. Additionally, the CSA provides policy advice to the Government of Liberia in key areas of the Civil Service including organization, staffing, pay and benefits, pension, conditions of service, and human resources development. Ultimately, the CSA ensures that the Liberian civil service is competent, professional, and motivated and that it meets the workforce needs of the Government and delivers quality, efficient services to the people of Liberia.
