Why does ALEKS periodically give me new Knowledge Checks?

 ALEKS will periodically reassess a student's knowledge to confirm their retention of recently learned topics and update their individualized learning path as they progress through a course. These Knowledge Checks may occur at regular intervals, or after the completion due date of a Module.

The results of these Knowledge Checks may indicate the need to further review topics previously deemed as "learned".  These topics, and perhaps others that are linked to them, are then returned to the Topic Carousel for additional practice. The ALEKS assessment mechanism ensures that students not only learn new concepts but also retain that knowledge.

Knowledge Check intervals:
1. After 20 topics are learned AND 5 hours are spent in learning mode
2. After 10 hours are spent in learning mode
3. After 60 days without a Knowledge Check, or after 30 days without a Knowledge Check for Higher Education Chemistry
