Single-Activity
A knowledge path can contain just one activity. Single-activity knowledge paths allow you to quickly create a path consisting of one title or content object only, along with any desired assessments.

Curriculum
A curriculum knowledge path includes multiple activities that have dependencies on each other. For example, a knowledge path called Working with Word 2003 consists of three activities: 1) Basic Word Skills; 2) Everyday Tasks Made Easier; and 3) Applying Formatting. By creating a curriculum knowledge path, you can show users that Basic Word Skills should be taken before Everyday Tasks Made Easier, and Applying Formatting should be taken last. You can set knowledge path options to require users to progress through each level of the knowledge path as structured, or allow users to navigate the path based on their knowledge base.

Organizational
An organizational knowledge path contains multiple activities that have no dependencies on each other. For example, a knowledge path called Microsoft Office Basics consists of four activities: 1) Access Fundamentals; 2) Basic Excel Skills; 3) Introduction to PowerPoint; 4) Introduction to Word. By creating an organizational knowledge path, you can display each activity at the same level, enabling users to navigate the activities in any order desired. Therefore, if the user wanted to take Introduction to PowerPoint before Access Fundamentals, he/she could in this scenario.

Note: It is possible to create curriculum knowledge paths within an organizational knowledge path.
