Participation in adult education and training (AET) programs is increasingly important for people of all ages and is necessary to remain competitive in a world experiencing rapid technological advances. Lifelong learning activities are especially important for middle-aged and older adults who intend to work at older ages to ensure they have the skills desired by employers. This study used data from three international surveys conducted between 1994 and 2015 to examine patterns of AET participation for ages 45 to 65 by employment status, comparing the US with Canada, Italy, and Norway. To contextualize these data, we also compared AET participation with employment and unemployment rates in the survey years for each of the countries. In all countries, the 45 to 54 age group participated in AET at higher rates than did the 55 to 65 age group and the employed participated at higher rates than did the unemployed and those not in the labor force.
