There are 65 directly elected members in the National Assembly. The other seats includes two non-elected ministers, two non-elected parliamentary secretaries and the Speaker. A maximum of four non-elected ministers and two non-elected Parliamentary Secretaries may sit in the National Assembly. If the Speaker is not an elected member, he or she becomes a member of the National Assembly by virtue of holding the office of Speaker. The National Assembly may thus have up to 72 members. The percentage of women is calculated from the current number of seats occupied in the parliament. The National Assembly has 72 statutory seats. (IPU Parline Guyana). 

25 of the 65 seats in the National Assembly are allocated by proportional representation in 10 geographical constituencies, ranging from 1 to 7 seats per constituency. The remaining 40 seats are elected from a national additional list in order to guarantee a very high degree of proportionality.
