Interest groups seek to maximize access points or centers of power and authority. They employ various techniques to achieve their shared interest. The specific techniques they employ vary from system to system. Most political science student have established in their final year project certain tactics used by pressure groups in Nigeria, but it has not been exhaustive. Generally, pressure groups may make use of the following techniques in the pursuit of their interests.

Lobbying :Lobbying is the practice of soliciting the support of members of a legislature with the intention of influencing legislation. It simply means attempts to influence legislation by persuading legislators and executives. It may take the form of personal contact and advertisement in the mass media to create a favourable public opinion for certain issues.

Provision of campaign funds: Pressure groups can influence the election of candidates by providing campaign funds. The elected representatives will invariably reciprocate by favouring those groups while in office.

Demonstrations and Strikes: Pressure groups can avail themselves of the powerful weapon of strikes and demonstration. They can resort to strike action, so as to paralyze the machinery of government. The demonstration against the police by Nigeria students over the killing of some ABU students in May 1986 influenced the Federal Military Government to recommend that the Nigerian Police should only make use of rubber bullets to disperse students during demonstration.

Propaganda: Pressure groups can embark on publication in the press bulletins, radio, television as well as hold public meetings to persuade the government for recognition of their interests.

Others include, boycott, refusal to co-operate with the government, revolution among other.
