By 1871, curricula had been organized in Agriculture, Engineering, and electives. The Maine Agricultural and Forest Experiment Station was founded as a division of the university in 1887. Gradually the university developed the Colleges of Life Sciences and Agriculture (later to include the School of Forest Resources and the School of Human Development), Engineering and Science, and Arts and Sciences. In 1912 the Maine Cooperative Extension, which offers field educational programs for both adults and youths, was initiated. The School of Education was established in 1930 and received college status in 1958. The School of Business Administration was formed in 1958 and was granted college status in 1965. Women have been admitted into all curricula since 1872. The first master's degree was conferred in 1881; the first doctor's degree in 1960. Since 1923 there has been a separate graduate school.
