Assumption School History

Assumption High School, built in 1929, became the source of advanced education for some Granger Homestead family members, and the school helped build self-reliance through classes such as building wood frame structures, furniture repair, and mechanical drawings.

During 1957, Assumption High School expanded. The gym, kitchen, dressing rooms and two classrooms were added to the complex. Class sizes and enrollment also grew.

Assumption’s High School was closed in 1966. The main grade school, however, remained open and covered all earlier grades. Assumption high school students either transferred into the local public school system or went to St. Josephs (girls) or Dowling High School (boys).

Recent external and internal updates to the campus have helped the school maintain its classic look and feel while meeting the current needs of the students and teachers – technology and current teaching practices are found abundantly inside this historic building.

Assumption School is a mainstay to the Granger community and continues to provide a high-quality Christian education in our Early Childhood program and a Catholic education to Kindergarten through Eighth grade children in the Granger, IA area. Please join us “Where Faith and Knowledge Meet!
