What is ALEKS?
Assessment
and LEarning in Knowledge Spaces is a Webbased, artificially intelligent assessment and learning system.
ALEKS uses adaptive questioning to quickly and accurately determine exactly what a student knows and doesn't know in a subject.
Instructions on how to take the assessment will appear after you enter ALEKS through your AccessPlus account.
All incoming students (both new freshmen and transferring students) must complete the ALEKS placement assessment before attending June orientation. Your placement into a Mathematics or Statistics course will be determined by your score on this placement assessment. It is strongly recommended that you take this assessment as soon as possible. This will leave you time to work on weak areas should you decide to retake the assessment (once) to qualify for the course(s) you want to take. At the latest, the assessment should be completed at least two weeks before you attend orientation.
The ALEKS assessment consists of 20 to 35 questions. Allow 12 hours to complete the assessment. No calculators are permitted during the exam. This is to prevent the biasing of placement into courses for which students are not adequately prepared.
Students with a documented disability requiring accommodations for an online assessment should contact the Iowa State University Disability Resources Office at 5152947220, TTY 5152946635 or disabilityresources@iastate.edu to discuss alternative arrangements.

If your ALEKS score does not qualify you for the course you expected or hoped to take, the assessment can be taken a second time, perhaps at the recommendation of an academic advisor. However, before retaking the assessment it is strongly advised that you complete a thorough review or remediation. There are several options for this review.

Take a Summer course at Iowa State University. This course should be a prerequisite for the course you hope to take in the Fall. If you earn a C or better in this course you will be admitted to the next course without retaking the ALEKS assessment. A list of Summer offerings in Mathematics will be posted as they become available.

Take one of the ALEKS “Prep” modules. These reviews are designed by ALEKS to address the areas of deficiency as revealed by the ALEKS assessment. The cost for a review module is $32.00. Click here for a table that will help you choose the right module based on your placement goal. You will be given the opportunity to purchase one of these modules by credit card after you take the assessment for the first time in accessplus.

Take a remedial course at another institution. If you choose this option you will still be required to retake the ALEKS placement assessment so we can be sure that you have mastered the topics that are prerequisite to the course you desire to take.
