When a learning specialist records an external learning event for a learner, they must select a completion source. This list of values (LOV) is populated from the WLFCOMPLETIONSOURCE lookup type. While this lookup includes more than four predefined values (such as Tutorials, Assignments, etc.), the options for Self-Paced Learning, Videos, Assessments, and Instructor-Led Training represent the most fundamental and distinct categories for classifying external learning activities. These cover the primary modes of content delivery (self-paced, video, instructor-led) and the primary method of formal evaluation (assessment).

A. Online events only: This is a valid lookup but is often considered a subset of self-paced or instructor-led training, making it less of a primary category than the chosen answers.

F. Tutorials: This is a valid lookup, but tutorials are a specific format of Self-Paced Learning, making option B a broader and more fundamental category.

G. Assignments: This is a valid lookup, but it is a type of learning activity often used for evaluation, similar to Assessments, making option D a more encompassing term.

H. Evaluations: This is a valid lookup, but it typically refers to feedback surveys (L1) rather than knowledge validation (L2), which is covered by Assessments.
