Moodle’s Gradebook aligns with the best practice in online pedagogy to provide learners with a well designed and up-to-date gradebook. However, if your gradebook needs some work, you can temporarily hide it until it’s ready:
Enter your Moodle course.
Expand the Actions Menu (gear Icon) in the top-right corner of the page.
Select the Edit Settings option.
Expand the Appearance section.
Change Show gradebook to students to Hide with the supplied drop-down menu.
Scroll to the bottom of the page.
Click the Save Changes button.
