Lower school average class sizes are 16-18 and middle and upper school average class sizes are 13-14.

Forbes magazine ranked Spence ninth on its "America's Best Prep Schools" list in 2010.^[5]

The Spence School was founded in 1892 by Clara B. Spence, who was its head for 31 years. The school's motto is "non scholae sed vitae discimus" (Latin for "Not for school, but for life we learn"). The first building was located on New York City's West 48th Street.^[6] The school once had a boarding option, but all current girls are day students.

Clara B. Spence described her school as: "A place not of mechanical instruction, but a school of character where the common requisites for all have been human feeling, a sense of humor and the spirit of intellectual and moral adventure."

Spence read from Shakespeare in dramatic declamation every week. She was known for her conservative comportment and strictness, but also her devotion to women's rights. She arranged for Edith Wharton, Helen Keller, and George Washington Carver to speak at the school. Isadora Duncan taught dance classes.^[7]

In a commencement address from an unknown year, Spence said that cultivating imagination was an important skill, since “sympathy, that great bond between human beings, is largely dependent on imagination—that is, upon the power of realizing the feelings and the circumstances of others so as to enable us to feel with and for them.”^[7]

The school has been located on East 91st Street since 1929.^[8]

Spence offers a liberal arts and science curriculum, including programs in the arts and foreign languages. In a Worth magazine study, out of the 31,700 private and public high schools in the United States, Spence ranked the sixth most successful school in the country in placing its graduates in Harvard, Yale and Princeton.^[9]
