The Iowa Valley Community School District is a rural public school district headquartered in Marengo, Iowa. The district spans areas of north-central Iowa County, including the town of Marengo, and the unincorporated area of Koszta, Iowa.
The school district is accredited by the North Central Association of Colleges and Schools and the Iowa Department of Education.
The district is a member of the South Iowa Cedar League conference. The mascot for both schools is the Tigers, and the school colors are orange and black.
, the district shares a superintendent with the English Valleys Community School District. The previous superintendent was scheduled to retire that year so the two districts sought a new one. The district is governed by a five-member board of directors, which meets monthly.
In 2021, Carl Rheingans was hired as superintendent, succeeding Mark Olmstead.
The first high school program in Marengo began in 1869, expanded to a four-year high school curriculum in 1871, and the first graduate was in 1872. In 1902, lightning struck the school building, destroying the third floor and belfry. The core of the current building, The Carson High School, named for the former superintendent, was built in 1925 and dedicated in 1927, though the school was still called Marengo High School.
In 1958, the school district consolidated and expanded to incorporate adjacent rural areas and changed the name from Marengo to Iowa Valley (based on the adjacent Iowa River). The name of the high school was also changed from Marengo High School to Iowa Valley High School. In 1972, a gymnasium, band/vocal music room and two science classrooms were added to the west end of the building.
The district operates two schools, both in Marengo:
The administrative offices are located at the high school.
Students at IVHS can participate in numerous activities, including band, choir, speech, drama, FCS, FFA, Student Council, and Yearbook.
