Upper School


Autonomy and a Burgeoning Sense of Purpose

Hewitt’s upper school celebrates the autonomy and burgeoning sense of purpose that come with young adulthood. Hewitt’s young women in grades 9 through 12 develop a keen understanding of how they learn, how they construct and manage their time and obligations, and how they both express their individuality and connect to their community, at school and beyond. Trained in the research on girls and young women, upper school faculty members foster inquiry, resilience, and collaboration in their classrooms, and students know and trust their teachers as wise and caring mentors.

Commencement Remarks to the Class of 2025: Changed for Good

This year’s Commencement theme, chosen by our seniors, is “Changed for Good.” And since we both began our careers as high school English and Latin teachers, we begin by explicating that phrase as meaning both changed for the better and changed forever. To honor the theme, and as parting words of wisdom to the Class of 2025, we will each share three stories from our own lives that have changed us for good.

Commencement Remarks to the Class of 2025: Life Is Not Always Lukewarm

If Hewitt has bettered us into any condition, state, or character, it would be that of a tea bag. What differentiates Hewitt students is the way we have been taught to approach struggles. We acknowledge the challenge, admit that it will be difficult, but remember that, as teabags, hot water is where we belong. It is where our flavor  – our power and strength – steeps best.
