The Redbirds also moved up four spots from No. 9 to No. 5 in the FCS Coaches Poll.
ISU's win against NU was the Redbirds' first victory against a Big Ten opponent in nine games and improved coach Brock Spack's record to 58-29.
Six Missouri Valley Football Conference teams, led by top-10 ranked teams North Dakota State (1), ISU (5), Northern Iowa (9) and South Dakota State (9) are ranked in the three polls this week.
