Rev. Walter A. Otto researched much of the material available on the history of the school and summarized it for the book published for the 25th anniversary of the dedication of Trinity Evangelical Lutheran Church in 1938, 25 years after the tornado destroyed it completely. The following is taken from that write-up.

"It has been the policy of the members of this congregation from its beginning to give the children a good secular education in a Christian day-school, when that was possible. According to that aim a Christian day-school was supported until 1931, with an intermission from 1915 to 1919. As early as 1885 student Carl Harwarth was employed to teach school. He received $20.00 a month. With this one exception no mention is made of help given the pastors in teaching up until 1900, when Miss Elizabeth Ketelsen was asked to prepare herself so that she could help out in school during the winter months.

In 1903 a school was built with the lumber from the dismantled 1884 church; four benches were made and others bought in Manning at 75 cents each. In the tornado-year the school year began on October 27, the day after the dedication of the present church. School began in 1914 but closed shortly after opening. The congregation passed a resolution to drop the school and it remained closed until 1919 when it resumed again, taught by Rev. Schliepsiek and his wife.

In 1920 an addition, 16 x 16, was built to the southwest side of the school, basement dug out, and a furnace installed. The Mission Board granted a student, Walter Friedrich, later pastor at Coon Rapids, to help in school.
