The Pembroke Hill School (usually referred to as Pembroke Hill) is a progressive, inclusive, secular, coeducational, independent preparatory school for about 1,200 students in early years (age 2 years) through high school, separated into four sections: early years-prekindergarten (early childhood school), kindergarten-5th grade (lower school), 6th-8th grade (middle school), and 9th-12th grade (upper school). It is located on two campuses in the Country Club District of Kansas City, Missouri, near the Country Club Plaza. Vassie James Ward Hill, a prominent Kansas Citian and Vassar College graduate born in 1875, gained a considerable fortune upon the death of her first husband, Hugh Ward, a son of pioneer Seth E. Ward. She then married Albert Ross Hill, formerly president of the University of Missouri. At the time, Kansas Citians of means commonly sent their children to boarding schools on the east coast. Hill did not want to send her daughter and three sons "back east." She believed they should be able to have an equal education in Kansas City. This led her to research the workings of college preparatory schools, especially the progressive education of the Country Day School movement. In 1910, using funds from 12 Kansas City businessmen, Hill founded the Country Day School for boys, which accepted both day students and boarders (boarding ceased in the 1950s). The initial enrollment was 20 students but grew to 52 within three years. It sat on what is today Pembroke Hill's Ward Parkway Campus, to the west of the Country Club Plaza at the intersection of State Line Road. Three years later, Ruth Carr Patton and Frances Matteson Bowersock joined with Hill to found the Sunset Hill School, named after Hill's favorite area on the Vassar campus. Sunset Hill was located on what today is Pembroke Hill's Wornall Campus, south of the Country Club Plaza. At the time of its founding, the campus overlooked the Kansas City Country Club (today Loose Park). It also includes a portion of the battlefield from the Battle of Westport. In 1925, some educators and students left the Country Day School to form the Pembroke School for boys. Their endeavor failed amidst the Great Depression, and the two schools re-merged in 1933 to form the Pembroke-Country Day School, keeping the Country Day School's original campus. It usually was referred to as "Pem Day." Merger From the start, Sunset Hill and Pembroke-Country Day worked cooperatively. Often, teachers taught at
