Increasingly, however, as the college admitted more students, it became more formalized. Somerville appointed Lilla Haigh as its first in-house tutor in 1882, and by the end of the 1890s female students were permitted to attend lectures in almost all colleges. In 1891 it became the first women's hall to introduce entrance exams and in 1894 the first of the five women's halls of residence to adopt the title of college (changing its name to Somerville College), the first of them to appoint its own teaching staff, and the first to build a library. In Oxford legend it soon became known as the "bluestocking college", its excellent examination results refuting the widespread belief that women were incapable of high academic achievement.
