Final answer:
Millennials, born between 1981 and 1996, are the most highly educated generation, having graduated from higher education institutions in large numbers despite economic challenges.
Step-by-step explanation:
The generation that is most highly educated is Millennials (those born between 1981 and 1996). This generation saw a significant number of individuals attending and graduating from higher education institutions, even amidst economic challenges like the recession and underemployment following their graduation. Millennials have been characterized by their technological sophistication and have marked attitudinal differences to previous generations, which in turn has affected their integration into workplaces structured by older generations, namely the Baby Boomers. Millennials' education level and their substantial presence in the workplace have led to innovative approaches in training and mentoring, including reverse mentoring to blend the technological prowess of younger employees with the experience of older employees.
