Singapore, like many other countries in the world, is on a journey towards a culture of lifelong learning to keep its workforce competent, resilient, and future-ready in the rapidly changing world of work. In order to realise this, a significant amount of resources has been invested to the training and adult education (TAE) sector. The TAE sector is expecting considerable and evolving skills demands from the TAE professionals specifically from the adult educators who are directly involved in the training delivery and development activities. With the high skills expectations from the profession, it is important to find out the level and predictors of work satisfaction among adult educators so as to provide necessary support for their performance and development. Work characteristics or quality indicators such as income, work autonomy, complexity, intensity, security, career prospect, professional development support, as well as work expectations were examined in relation to adult educators' work satisfaction. Multivariate analyses show that work autonomy, job security, and professional development support are strong determinants of work satisfaction among adult educators, even after considering adult educators' work expectations and other employment and individual characteristics.
