Competent adult learning facilitators play a vital role in improving the quality of adult learning programmes. This article thus explores common and core competences of adult learning facilitators from the perspective of key stakeholders, such as facilitators, adult learners and administrators. By synthesising previous international studies, we developed a survey and collected data in Mongolia (n = 227). We identified adult learning facilitators’ common and core competences focusing on their teaching role. As found, areas of adult learners’ needs assessment, communication and motivation should be integrated in professional development programmes in order to aim for a better completion rate and higher participation of target audiences in adult learning programmes.

合格的成人学习促进者在提高成人学习计划的质量方面起着至关重要的作用。因此，本文从主要的利益相关者（例如，促进者，成人学习者和管理者）的角度探讨了成人学习促进者的共同和核心能力。通过综合以前的国际研究，我们开展了一项调查，并收集了蒙古的数据（n  = 227）。我们确定了成人学习促进者的共同能力和核心能力，重点是他们的教学角色。可以发现，成人学习者的需求评估，沟通和动机领域应纳入专业发展计划中，以期达到更高的完成率，并使目标受众更多地参与成人学习计划。
