It is likely that Maverick's early education took place at home. In early 1822, he traveled to Ripton, Connecticut, to study under a tutor. In September of that year he was admitted to Yale University as a sophomore. At Yale, he was known as "Sam". After graduating in 1825, Maverick returned to Pendleton and apprenticed under his father to learn business affairs. For the next year, his father deeded him land, and on February 4, 1826, he made his first land purchase, acquiring half a lot in Pendleton.
