Adult Continuing Education (ACE) provision is increasing all over the world. Nonetheless, the gap between high- and low-skilled adults has also become wider. The growth in ACE opportunities has  not been accompanied by the necessary commitment to research on ACE theories, strategies, policies, methods and tools. To fill this lacuna, it is necessary to strengthen cooperation in the field of research among scholars and practitioners who can renew, expand and deepen the knowledge base of ACE in their own areas of expertise.

     For this purpose, the Lifelong Lifewide Learning journal will dedicate Issue nr 1/2024 to contributions from scholars and practitioners from different continents who wish to share their studies and propose emerging ACE themes. These themes will subsequently be developed in forms of worldwide cooperation, collaboration and comparison.
