Separate content from the attempt.
A lesson is the material presented. An attempt records a learner's activity under particular rules. Define what action establishes completion rather than assuming that opening a page is enough.
Resources / Progress records
A completed lesson needs a clear definition.
The course structure and the progress record need to describe the same learning requirement.
Account for course changes.
In a fictional onboarding course, a revised policy lesson may need a new acknowledgment. Decide whether earlier completion remains valid and retain enough version information to explain the report.
Define assessments and corrections.
Specify passing conditions, allowed attempts and authorized manual corrections. Staff should be able to distinguish a learner result from an administrative adjustment.
Explain the report's limits.
A completion record reflects the defined platform rule. It does not by itself prove comprehension, professional competence or regulatory compliance.
