ALEKS
support at every step

ALEKS PPL empowers students to be prepared and successful in their proper math course, expediting their path to completion.


Efficacy and Case Studies

Utah Valley University

ALEKS PPL has saved students approximately $1,000,000 in tuition by helping them to skip math courses that would otherwise have impeded their academic track.

UVU uses ALEKS PPL for all students and also offers a guided placement preparation 1 credit hour course taught by full-time faculty.

Iowa Central Community College

Iowa Central increases STEM enrollments by 21% and also sees a correlation to overall course success rates with ALEKS PPL.

Prior to ALEKS PPL, College Algebra courses had a success rate of 34% and now with the accuracy of PPL, success rates are at 74%. Non-traditional students are also succeeding at higher rates.

Oklahoma State University

Overall DFW rates decrease by 15% after implementing PPL and by 10% for Calculus. 

Oklahoma State has also used the diagnostics to inform which topics are critical to review in Calculus as well.

University of Illinois

ALEKS PPL scores are a statistically significant measure of course success at University of Illinois.

A re-designed approach to placing students in Calculus reduces failure and withdrawal rates dramatically for two consistent years, and benefits courses campus-wide that rely heavily on PreCalculus and Calculus.
