* Advanced degrees: This is the most common indicator. It could mean holding a postgraduate degree like a Master's degree, a Doctorate (PhD, MD, JD, etc.), or other professional degrees requiring extensive study beyond a bachelor's degree.
* Prestigious institutions: Attending and graduating from highly selective and renowned universities or colleges can also contribute to being considered highly educated.
* Extensive specialized knowledge: It's not just about the number of degrees, but also the depth and breadth of knowledge acquired. A highly-educated person often possesses specialized expertise in a particular field.
* Exceptional academic achievement: High grades, scholarships, academic honors, and publications throughout their educational career are often indicators.
It's important to note that "highly-educated" is a relative term. What constitutes "highly educated" can vary depending on the context, the field of study, and cultural norms. Someone highly educated in one area might not be considered so in another. Furthermore, it doesn't necessarily equate to intelligence, wisdom, or practical skills outside of their area of expertise.
