AEIP has many different working groups which set the agenda and the different strategies for the association in its lobbying campaign to the European and Intergovernmental Institutions. The three categories of working groups are: the Technical Committee, Task Forces and Scientific Council.

The Technical Committee breaks down into three Statutory Commissions which are the most important working groups for AEIP. These three Statutory Commissions are made up of the representatives of the Associated Members and it allows for the Observer Members to attend the meetings without decisional power. The Commission I works with the EU Coordinated Retirement Schemes in the first pillar. Commission II focuses on all issues surrounding occupational Pension Funds. And Commission III deals with Healthcare and Provident Benefits.

In addition to the Statutory Commissions, AEIP has six Task Forces. Task Force Construction; Task Force Health and Safety at Work; Task Force Paid Holiday Schemes; Task Force Health and Care; Task Force Territorial Social Protection Schemes and Task Force Metal Industry

Typically, these task forces meet four times a year. All Associate Members and Observer Members can participate in any task force meeting. Additionally, any other organization, even a non paritarian one, may join and participate in AEIP task forces. Furthermore, during these meetings the current issues are discussed in great detail and the results sometimes set the agenda for the Statutory Commissions providing a framework for drafting of working documents.

The last working group of AEIP is the Scientific Council. It is made up of highly-qualified university professors and representatives from law firms and other organizations such as research institutions. The Scientific Council helps map out the current trends in social protection as well as providing new information on recent academic works in the area, as well as the possible steps for the next activities of the organization.
