In 1807, Willard left Berlin and briefly worked in
Westfield, Massachusetts, before accepting a job offer at a female academy in
Middlebury, Vermont. She held the position of principal at the academy from 1807 to 1809. She was unimpressed by the material taught there and opened a boarding school for girls, the
Middlebury Female Seminary in 1814, in her own home. She was inspired by the subjects her nephew, John Willard, was learning at
Middlebury College and strove to improve the curriculum that was taught at girls' schools. In her speech to the legislature, Willard said that existing women's education was inadequate both in the amount girls received compared to boys and in its foundational principles. One issue she took was that women's education "has been too exclusively directed, to fit them for displaying to advantage the charms of youth and beauty". Another was "it has been made the first object in educating our sex, to prepare them to please the other" while "reason and religion teach, that we too are primary existencies... not the satellites of men." Her plan included a proposal for a women's seminary to be publicly funded just as men's schools were. The
Troy Female Seminary opened in September 1821 for boarding and day students. This was the first school in the United States to offer higher education for women. The curriculum consisted of the subjects she had longed to include in women's education: mathematics, philosophy, geography, history, and science. Willard led the school to success, and in 1831, the school had enrolled over 300 students. The school attracted students from wealthy families or families of high position. Although most of the students would still end up as housewives, Willard never hindered her students' pursuit towards women's education and continued to fight for their rights. Despite her reputation today in women's history, Willard was not a supporter of the
women's suffrage movement during the mid-19th century. Willard believed that women's education was a much more important matter. ==Marriage and family==
