Due to the breadth of his academic goals, Maier studied at Harvard Divinity School from 1916 to 1918, and at Harvard Graduate School of Arts and Sciences from 1918 to 1920. These four years saw the completion of course requirements for both Master of Arts and Doctor of Philosophy degrees, and the creation of a first draft of his doctoral dissertation, Slavery in the Time of the Hammurabi Dynasty. His perspicacity concerning Biblical Hebrew led to the mastery of other Semitic languages such as Arabic, Assyrian, and Babylonian, as well as the Hittite and Sumerian languages; and included the ability to read ancient cuneiform. The study of Semitics also led to his deep understanding of the history, literature, and culture of the ancient societies associated with these languages. In 1917, Harvard Divinity School awarded Maier the Billings Prize for oratory. He received an M.A. in Semitic language, literature and history from Harvard University in 1920; and in 1929 became the twentieth person to ever receive his doctorate from Harvard in Semitics. Since America's oldest college had been founded in 1636, an average of one successful candidate every fifteen years had received this degree.
