ALEKS Math Assessment

What is ALEKS?

To place students into appropriate math courses, Clark College uses an assessment called ALEKS (Assessment and LEarning in Knowledge Spaces), a Web-based, artificially intelligent assessment and learning system. ALEKS avoids multiple-choice questions and uses adaptive questioning to quickly and accurately determine exactly what a student knows and doesn't know.  Please note: ALEKS may not be taken after getting a letter grade (A - F) in a math course at Clark.

Can I retake ALEKS?

Students are allowed a maximum of five attempts at the ALEKS assessment - however, the first assessment may be taken at home as a practice test. Students are required to spend at least three hours in the Prep and Learning Modules between retakes, and the highest score is always used for placement. 

When and where can I take a proctored exam?

Proctored assessments are offered at the following locations:

Gaiser Hall 128

Located in the Enrollment Services office during check-in hours on a walk-in basis only (no need to schedule an appointment).

Testing services are offered on a limited basis at the Student Services office at the Columbia Tech Center campus.
Please call (360) 992-6100 for available times prior to testing.

Check-in Hours:

Monday - Thursday
8 a.m. - 3 p.m.

8 a.m. - 10 a.m.


Test registration can be completed upon arrival; unlike our English Readiness Assessment (ERA), there is no need to register 24 hours in advance.  Students take 60 to 90 minutes on average for the ALEKS assessment.

What do I need to bring?

Students are required to present a photo ID upon check-in, and knowing your student ID number will speed up registration. Scratch paper and pencils are provided, but calculators are not allowed. For specific questions only, ALEKS provides a calculator in-browser.

How can I prepare?


The first (and only the first) attempt at the assessment can be taken as a practice test at home. Students are encouraged to take the practice test, as it is good preparation for the proctored attempts. Upon completion, students can view their results by topic. These topics can then be studied in the Prep and Learning Modules before taking a proctored assessment at the Assessment Center. 

To access the practice test, students must provide their student ID number in a request for access from the Assessment Center at (360) 992-2588,, or in-person (Gaiser Hall 128). If students do not want to take the practice test, however, their first attempt may count as a proctored attempt if taken in the Assessment Center. 

When do I complete the ALEKS Prep and Learning Modules?

Students are required to spend at least three hours in the modules between retakes (students have module access after completing the first exam, either as a practice test or a proctored assessment). According to McGraw-Hill, 85% of students who spend five or more hours in the Prep and Learning Modules score high enough to place into a higher math course. Students can spend an indefinite number of hours in the modules. 

How do I receive my score and math course placement?

Students can view their score and corresponding placement immediately after completing an assessment. The screen will show all of the ALEKS score ranges and corresponding math courses, and the student’s score and corresponding courses will be highlighted. Students may request a printout of this screen.
