Why Study at SJI?

When we stand in the presence of a powerful sculpture or gaze through the eyepiece of a telescope and see a distant nebula, there is an extended moment of awe when we are transfixed with wonder. The desire to understand what we see, to know its story, prompts us to ask questions and seek answers. At SJI, we strive to recreate this moment, to ask these questions, and to know these stories in every subject we teach. From the epic tales of Odysseus and Beowulf to the quiet heroism of Walter Ciszek in Soviet Russia, from the deceptive simplicity of counting to the surprising complexity of the natural logarithm, SJI presents the inspiring beauty of our world in ways that lead students to deeper understanding and lifelong mastery.
