In order to revive the college, Diehl implemented a number of reforms: the admission of women in 1917, an honor code for students in 1918, and the recruitment of Oxford-trained scholars to lead the implementation of an Oxford-Cambridge style of education. Diehl's application of an Oxbridge-style tutorial system, in which students study subjects in individual sessions with their professors, allowed the college to join Harvard as the only two colleges in the United States then employing such a system. During Diehl's tenure as president, he would add more than a dozen Oxford-educated scholars to the faculty, and their style of teaching would form the foundation of the modern Rhodes curriculum.
