Spacing effect
The empirical finding, documented since Ebbinghaus's 19th-century research and replicated across domains, that active recall at increasing time intervals produces substantially more durable retention than massed re-reading of the same material (Roediger and Karpicke, Psychological Science, 2006). Operational implementation: recall at two days, five days, and two weeks after initial study.
Defined in 3 GAGE programs, which carry 3 distinct definitions of it. The wording above is taught in Foundations of Robotics and Physical AI.
How each discipline defines it
The same term does different work depending on who is using it. These are the definitions as each program teaches them, unedited.
The empirical finding, documented since Ebbinghaus's 19th-century research and replicated across domains, that active recall at increasing time intervals produces substantially more durable retention than massed re-reading of the same material (Roediger and Karpicke, Psychological Science, 2006). Operational implementation: recall at two days, five days, and two weeks after initial study.
The finding, with roots in Ebbinghaus's nineteenth-century forgetting-curve research and confirmed at scale by Cepeda, Pashler, Vul, Wixted, and Rohrer's 2006 meta-analysis, that distributing study of the same material across multiple separated sessions produces stronger long-term retention than massing the same total study time into one session.
The robust finding that the same total practice produces more durable learning when distributed across multiple sessions over time than when crammed into one (massed) session.

Where it shows up at work
A definition is where Spacing effect starts. The lessons above teach it inside the competencies below, which are what job descriptions ask for and what the GAGE credential records. Every link here is drawn from the same careers map that builds a role's readiness check.
Designs role-based AI training that measures skill, not attendance, with approved-use guidance, office hours and communities of practice.
One lesson on this page teach it as a primary outcome.
Roles that hire for it
Each role page shows the full competency set, what the seat decides, and a readiness check against your own evidence.

How job descriptions say it
Postings rarely use the textbook word. These are the phrases the careers map reads as asking for the competencies above.
Where the frameworks place it: EU AI Act Article 4; DOL AI Literacy Framework.
One interview question about it
Design AI literacy training for a workforce of mixed skill. Who learns what, and how do you know it worked?
Asked of candidates for ai literacy training and enablement design. Answering it in your own words is exactly how a GAGE topic is passed, and the credential records the pass where an employer can check it.
If you come from another field
Some backgrounds already carry this competency, and the readiness check gives credit for it.
- Human resources and people operations carries it as a claim to back up: Training design and delivery are part of the function.
- Operations, claims, customer service and administration carries it as a claim to back up: Onboarding and job aids are training design.
- Teachers, trainers and instructional designers carries it as work you can show: Lesson plans, assessments and curricula are your artifacts.
