Combatant Clergy Association (Persian: جامعۀ روحانیت مبارز), Association of Combatant Clerics (Persian: مجمع روحانیون مبارز), and the "Coalition of the Oppressed and Deprived" were the three most important and active organizations in the elections.

Due to the election propaganda atmosphere and the tendency of the people to the left wing (Association of Combatant Clerics, Persian: مجمع روحانیون مبارز) and due to the slogans of justice and equality and the defense of the deprived and oppressed by the Association of Combatant Clerics, it led to a significant victory of the left-wing electoral groups in the elections.

The characteristics of the third term of the Islamic Consultative Assembly elections include the following:[4] The constitution approved in a December 1979 referendum provided for a 270-seat Majlis, with five seats reserved for minority groups including Jews, Zorastrians, Armenians from the north and south of the country and one jointly elected by Assyrians.

One of the differences between this period and the previous one was the disagreement between the Guardian Council and the Ministry of Interior as to which of the institutions was legally entitled to review the eligibility of the candidates.

Pursuant to Article 50 of the Electoral Law and Note 1, the Executive Directorate of Elections was obliged to take the necessary steps to qualify the candidates through the competent legal authorities after registration and to announce the names of those candidates who met the legal requirements.

Finally, the Interior Ministry's election campaign, which saw the continuation of disagreements and conflicts with the Guardian Council's central oversight board as delays in holding elections, exerting more military pressure on the Ba'athist regime in Iraq, escalating urban warfare and destabilizing the "Islamic" Republic of Iran, sought to ensure 'Opinions of the Central Board of Supervisors of the Guardian Council' to end the disagreements.

He continued to insist, however, that oversight boards had departed from their legal and impartial position and tended to openly side with one faction.
