The Assembly has legislative, representative and oversight functions.

Most of the proposed laws in Parliament originate in the National Assembly. As the main law making body, the Assembly deliberates, amends, repeals and passes laws. Besides bills introduced by the (executive) government, individual members can initiate legislation. 

Assembly members represent the people in Parliament by voicing their concerns when laws and policies are formed and discussed. They also keep the people informed of Parliament decisions and government development programmes through regular constituency visits.

The Assembly exercises its oversight functions by questioning government ministers and reviewing policies to ensure that public funds have been utilised for the intended purpose. It also collaborates with other oversight institutions such as the Royal Audit Authority and the Anti-Corruption Commission that monitor government performance.
