Previously Renwick was served by the Boone Valley Community School District, which operated the Boone Valley School, built in 1915, in Renwick. On January 1, 1988, the Boone Valley district dissolved, with a portion absorbed by other school districts. That year the Boone Valley School closed, and in 1989 alumnus Frank Siemens and his family bought it for $5,000. The business Boone Valley Implement is in the former school. By 2015 Siemens spent $500,000 to refurbish the building. In 2015 Jason Clayworth and Charles Litchfield of the "Des Moines Register" stated "A large portion of the older section of the school remains relatively unused."
