Schulzentrum Marienhöhe or Marienhoehe Academy is a private K-13, co-educational Christian boarding school in Darmstadt, Germany. It is owned and operated by the Seventh-day Adventist Church. In 1924, a group of Seventh-day Adventists bought a former gym and dance studio from Elizabeth Duncan. The authorities in the state of Hesse then approved the establishment of a mission school. In 1925, a new building for the school workshops was built. Over the years, the number of workshops grew to nine: locksmith, carpentry, printing, upholstery, mattress manufacturing, knitting and others. Many students earned money from these workshops, with which they used to pay their tuition fees. Also, the number of teaching departments expanded. There was a seminary, a business school, a housekeeping school, preschool and nursing courses for educators and kindergarten teachers. In the 1927/28 school year, the school expanded to include a six-year course of preparation for higher education - today's high school equivalent. The students were prepared for graduation, at Marienhöhe, and entered into tertiary education in the Darmstadt region.
