The parliament has always been recognized as an important decision-making body in the political structure of societies. Therefore, the need to evaluate the performance of this institution is of great importance. If we evaluate the actions and performance of this institution, we can hope to improve its performance. Because behind evaluation is accountability. Accountability is a social relationship in which the person or institution being evaluated promises to provide appropriate justification for their actions. Therefore, the evaluation process will lead to transparency in the functioning of the parliament. Since the parliament is an institution that influences the life of the general public with its decisions, the need to improve its performance is considered important because it can lead to the realization of collective goals in societies. In this regard, the development of necessary mechanisms in order to achieve this goal deserves attention and the parliament can take an important practical step in this direction by resorting to the mentioned mechanisms. Therefore, the purpose and innovation of this study will be to provide the necessary mechanisms to evaluate and improve the performance of parliament. Obviously, if the actions of the parliament are transparent and improved, the collective interests of the general public can be guaranteed.
