The first postwar class graduated in 1871. During the 1873-74 school year, there were 115 students enrolled-95 students of high school age at the academy level and 20 at the college level. A Theological Department was added for aspiring ministers unable to attend a regular seminary. A Commercial Department was added in the 1890s. At its zenith, the college offered the B.A., B.S., and Ph.D. degrees. During the next 29 years, 66 men graduated from North Carolina College, and most entered the learned professions. At least 28 of them became Lutheran ministers. By 1900 enrollment at North Carolina College had dropped to 56 students, and financial problems worsened. The class of 1901 was the last to graduate from the college.
In 1859 a Lutheran school for young women was established in Mount Pleasant, with Mrs. D. H. Bittle, the wife of a Lutheran minister, as principal. Her husband was then serving as president of North Carolina College. The school was first known as Mount Pleasant Female Seminary. In 1892 school officials changed its name to Mont Amoena Seminary, using the Latin version of the town's name. In 1868 G. D. Bernheim, who was then in charge of the school, offered to transfer it to the synod on favorable terms. The transfer was completed in 1869, and the first board of trustees of the school was elected. Mont Amoena had 112 students by 1897.
In 1903 a school named Mount Pleasant Collegiate Institute began operating on the campus of the then-defunct North Carolina College. The Lutheran Synod resumed sponsorship of the institute, which retained the original purpose of preparing young men for the seminary and other professional careers. During the 1903-4 school year, 3 teachers taught 52 students at the institute; by 1923 there were 8 teachers, 173 students, and some 200 alumni.
At the Mount Pleasant Female Seminary, the financial situation was more stable. The seminary burned on 30 Nov. 1911, but a large, new brick structure soon replaced the burned frame building. The school was quite successful for about half a century, but after a time it became increasingly difficult for it to compete with newer facilities such as Elizabeth College in Charlotte. Public high schools also began duplicating the work of the seminary, and Mont Amoena finally closed its doors in 1927. Thereafter, the first female students were allowed on the campus of Mount Pleasant Collegiate Institute as day students.
Prior to the merger of the North Carolina and Tennessee Lutheran Synods in 1921, the Mount Pleasant Collegiate Institute could depend on some funding from the synod and from individual Lutheran congregations. After the merger, however, it became even more difficult to obtain adequate funding, as the institute had to compete with more successful institutions such as Lenoir-Rhyne College. Fees and tuition alone were simply not adequate to fund the school's continued operation. Economic necessity finally forced the school's permanent closing in 1935.
