Assumption High School is a Catholic all-girls high school located in Louisville, Kentucky, sponsored by the Sisters of Mercy. History The history of Assumption High School began in 1951 when the Most Reverend John A. Floersh, Archbishop of Louisville, asked the Sisters of Mercy to establish a new high school at the corner of Bardstown Road and Tyler Lane. The school first opened on September 6, 1955. In that first year, tuition was $100 and the student body consisted of 103 freshmen and 50 sophomores. The first principal was Sr. Mary Prisca Pfeffer, and the faculty consisted of five Sisters of Mercy. Another sister served as the cook and was the only staff member. For three years, the sisters lived on the third floor of the school until there were finally enough funds to build a separate convent. Their current Principal, Martha Tedesco, graduated from Assumption in 1990. Current enrolment is almost 900 young women, grades 9-12.
