There is a growing international interest in ethical issues in research and the process by which it can be enhanced. Unlike in the past when research studies were conducted abruptly, almost all organisations and research institutes now have various mechanisms to ensure compliance with ethical standards and procedures. Adult and community education research in Nigeria continues to gain the attention of governments and Non-governmental organisations (NGOs) due to the need to improve the literacy rate among adult learners and out-of-school youths in the country. However, in many workshops and training involving academics and development workers, much of the discussions on ethical issues in data collection and research reportage are not given the necessary attention that it requires. This review paper explores the ethical issues in adult and community education research with a view to re-awakening the consciousness of adult education scholars and practitioners, both in Nigeria and on the continent of Africa, to rethink how research data and processes are managed, such that it conforms with best practices globally.
