How can we help you?

You can lock subsections of your course until learners complete other prerequisite subsections.  

If a subsection has a prerequisite, it is displayed in the course outline with a lock icon. Learners cannot view the subsection content until they have achieved a minimum score in the prerequisite subsection.  

Note: 
You must first enable course prerequisites before prerequisite course subsections can be used. See the end of this article for support on enabling this option.

Create a Prerequisite Subsection

To prevent learners from seeing a subsection until they have achieved a minimum score or completed a minimum portion in a prerequisite subsection, follow these steps.  

Note:  

• Configure subsection prerequisites in the order that you intend learners to encounter them in the course. The system does not prevent you from creating a circular chain of prerequisites that would permanently hide them.  

• You cannot use Open Response Assessments with a point value of 0 as prerequisites for other subsections.  

Steps

1. Ensure that subsection prerequisites are enabled for your course (see above).  

2. Select the Configure icon for the subsection that must be completed first (the prerequisite subsection).  

3. Open the Advanced tab.  

4. Under Use as a Prerequisite, select Make this subsection available as a prerequisite to other content.  

5. Select Save.  

6. Next, select the Configure icon for the subsection that will remain hidden until the prerequisite is met.  

7. Open the Advanced tab and locate the Limit Access section.  

8. In the Prerequisite list, choose the subsection you want to require as a prerequisite.  

9. Configure access conditions:  

   • Minimum Score: Enter the percentage of the total score learners must achieve in the prerequisite subsection.  

     • Example: If the prerequisite subsection includes four problems of equal value, set Minimum Score to 75 to require at least three correct answers.  

   • Minimum Completion Percentage: Enter the percentage of the prerequisite subsection that learners must complete.  

If both Minimum Score and Minimum Completion Percentage are set above zero, learners must satisfy both conditions before the subsection unlocks. The default value for both fields is 100.  

10. Select Save.  

Indicators in the Outline

In the course outline, if a subsection has a prerequisite, the prerequisite name appears under the subsection title, along with a lock icon.  

Note: 
Prerequisite subsection settings are not retained when you Export and Import a course, or when you re-run a course.  

How to enable Subsection Prerequisites

If your course does not show the option to use prerequisites at the subsection-level, you will need to enable prerequisite subsections in a course, follow these steps:  

1. From the Course Toolbar, select Advanced Settings from the "Settings" dropdown menu.  

2. In the Enable Subsection Prerequisites field, enter true.  

3. Select Save Changes.
