Regent Admission Index
Students who wish to enter Iowa State University directly from high school will be admitted based upon their Regent Admission Index (RAI) score. There are two mathematical formulas for computing student's RAI scores, the primary RAI formula (for students whose high school provides class rank) and the Alternative RAI formula (for students whose high school does not provide class rank). Below is a detailed description of each formula:
|Primary RAI Formula (for students whose high school provides class rank)||Alternative RAI Formula (for students whose high school does NOT provide class rank)|
|Percentile class rank x 1 + ACT composite (or converted SAT) score x 2 + Cumulative GPA x 20 + Number of years of high school core courses x 5 RAI score||ACT composite (or converted SAT) score x 3 + Cumulative GPA x 30 + Number of years of high school core courses x 5
Applicants who achieve at least a 245 RAI score and who meet the minimum high school course requirements will automatically be offered admission. Applicants who achieve less than a 245 RAI score and who meet the minimum high school course requirements may also be offered admission, but their applications will be reviewed on an individual basis.

Students who wish to enter Iowa State University directly from high school must also meet the minimum high school course requirements for admission as indicated below:
|English/Language Arts||4 years||Emphasizing writing, speaking, and reading, as well as an understanding and appreciation of literature|
|Mathematics||3 years||Including one year each of algebra, geometry, and advanced algebra.|
|Science||3 years||Including at least two years of courses which emphasize elements of biology, chemistry, or physics.|
|Social Studies||2 years|
Additional entrance requirements for the Colleges of Engineering and Liberal Arts and Sciences
In addition to the high school course requirements listed above, students applying for admission to the College of Engineering must complete two years of a single foreign language. Students applying for admission to the College of Liberal Arts and Sciences must complete a third year of social studies and two years of a single foreign language.
Nontraditional students are held to the same high school course requirements as all entering freshmen. However, because research has shown that traditional measures of high school performance (e.g., GPA, class rank) are not always good predictors of academic success for nontraditional students, those who achieve less than a 245 RAI score are still encouraged to apply for admission.
General Equivalency Diploma (GED)
General Equivalency Diploma (GED) applicants are welcome to enroll at Iowa State University. The specific GED score requirements for admission depend upon when the GED test was taken.
GED taken prior to 2014
Applicants who have achieved an overall average score at the 50th percentile or higher with no score lower than the 45th percentile will be offered admission. Applicants are also required to achieve GED sub-test scores at the 75th percentile for subject areas in which they did not satisfy the Minimum High School Course Requirements for Admission.
GED taken in 2014 or later
Applicants who have achieved a score of 170 or higher on each of the four content areas (Reasoning Through Language Arts, Mathematical Reasoning, Science, and Social Studies) will be offered admission.
High School Equivalency Test (HiSET)
In January, 2014, the state of Iowa began using the HiSET (in place of the GED) as the assessment for persons who wish to earn their high school equivalency diploma. The HiSET is composed of five sub-tests listed below, each of which are scored from 1-20 with a score of 8 considered "passing" and a score of 15 considered "college ready". The total HiSET score ranges from 1-100.
- Language Arts – Reading
- Language Arts – Writing
- Social Studies
Freshman applicants who achieve a minimum sum score of 75 on the HiSET and a minimum score of 15 on each of the five sub-tests will automatically be offered admission. Applicants who do not meet these minimum requirements will be considered on an individual basis.
Home schooled students
Each year, Iowa State welcomes freshman applicants who have been educated at home.
Because all of the factors which make up the RAI are typically not available for home schooled students, all home schooled applicants must undergo an individual review before an admission decision is made.
In addition to submitting the freshman application for admission, home schooled students must also submit the following items:
- Home school transcript. For each core course the student has studied, the transcript should include the subject title, text book used, and course syllabus.
- High school transcript if any courses have been taken through the local high school.
- College transcript(s) if any college coursework has been attempted.
- Official ACT or SAT scores (must be received directly from the testing agency).
Please contact the Office of Admissions for additional details.
Students with disabilities
Students with documented disabilities are held to Iowa State's regular freshman admission requirements. Those who feel their academic record does not accurately reflect their ability to succeed and, therefore, wish to be considered for admission on an individual basis are asked to submit additional documentation explaining their circumstances. This documentation should include:
- A letter from the applicant requesting special consideration. This letter should identify the disability and include a description of how the disability impacts academic performance.
- Information pertaining to accommodations and services used in high school or the most recent educational setting.
- A recent typed report prepared by a qualified provider that contains a specific current diagnosis, treatment history, and existing functional impact as it relates to one's participation at Iowa State University. Please refer to Student Disability Resources Web site for more details on documentation requirements.
