Accelerate Math Achievement with ALEKS® K–12

ALEKS (Assessment and Learning in Knowledge Spaces) is a personalized math learning accelerator that helps K–12 students reach mastery more than 90% of the time. Backed by more than 25 years of research, this transformative program pinpoints the math concepts each student does and doesn’t understand before generating the individual support required to achieve mastery.

The ALEKS Difference

ALEKS focuses each student on the exact skills they need to fill knowledge gaps, accelerate to grade-level learning, and prepare for future math success. With adaptive learning paths aligned to standards for all 50 states, you can be confident your students are developing critical skills at a level that’s just right for them. As students advance from kindergarten through high school, ALEKS grows alongside them with increasingly challenging math concepts, leveled-up user experiences, and age-appropriate graphics.

Filling Gaps and Accelerating Beyond 


ALEKS provides targeted supplemental practice for every student, whether they are working to fill knowledge gaps, learning on-level, or accelerating beyond:

  • The Initial Knowledge Check accurately determines what each student knows, doesn’t know, and is ready to learn next.
  • The ALEKS Pie visually depicts how much a student knows and how much they have left to learn within each topic area.
  • Prerequisite topics are built into every grade-level course, making it easier for students to efficiently fill prior-year gaps and access grade-level content.

Increasing Retention and Mastery

ALEKS propels students to mastery with features that promote deep conceptual understanding:

  • Periodic Knowledge Checks provide retrieval practice and measure retention.
  • Distributed practice builds long-term mastery as students are guided to revisit topics they have yet to retain.
  • An emphasis on free-response question types ensures that students demonstrate their understanding rather than guess their way to completion.

Fostering Independence and Flexibility

ALEKS is built for every classroom and every learner:

  • Immediate feedback and targeted learning aids empower students to push through moments of productive struggle.
  • For multilingual learners, one-click Spanish translation provides access to math content.
  • Minimal teacher setup makes it easy to facilitate seamless, ready-to-use, independent learning.

Actionable Data

Real-time, customizable reports empower teachers and administrators to make data-driven decisions with ease:

  • Teachers can monitor student activity, identify who needs support, and access daily recommended topics with ready-made instructional groups.
  • Administrators can track district-wide learning rates, activity time, and standards progress or drill down by school and grade level.

How It Works

The only adaptive program to use Knowledge Space Theory, ALEKS guides each student on an individualized journey through various learning states—because research shows that we do not progress linearly from one state to the next. By efficiently developing and maintaining a detailed map of each student’s evolving knowledge, ALEKS intelligence empowers students to work at the boundaries of their current understanding.
