Notre Dame de la Baie Academy was established in 1990 when three former Catholic high schools, St. Joseph Academy (an all-girls school founded in 1896), Abbot Pennings High School (an all-boys school founded in 1898 as St. Norbert High School), and Our Lady of Premontre High School (an all-boys school founded in 1941 as Central Catholic High School that had recently turned co-ed), consolidated. The consolidation was necessary to provide the best high school education to area students. Students and staff from the previous three high schools joined together to create Notre Dame de la Baie Academy; they chose the school's name, colors, crest, and mascot with the mission of building upon the strong foundations established and built by Notre Dame's predecessor schools.


The crest of Notre Dame de la Baie Academy represents the rich heritage of the school. At the center of the crest is a shield in which the dominant symbol is the cross of Jesus Christ. Blazing forth from the cross are rays of light which denote Christ's Resurrection. The crescent moon in the lower left of the shield represents Mary to whom the school is dedicated. In the lower right section is the flowering lily, a traditional symbol of St. Joseph. Flanking the shield on both sides is the fleur-de-lis, French lily, suggesting the French founding of both the Sisters of St. Joseph of Carondelet (St. Joseph Academy) and the Order of Premontre (Norbertines). The fleur-de-lis also reminds us of the French heritage of the Green Bay-De Pere area. The four waves in the lower section of the crest represent the waters of Green Bay. These waves draw together the four alumnae/alumni communities represented at Notre Dame de la Baie Academy.
