School Manager Filtering Categories Guide

This article is intended for School Manager and Classwize users.

School Manager utilizes "Categories” to label each website or connection and block or allow access to it based on your school's filtering policies. Categories can have Subcategories and Signatures, allowing users with the Filtering Administrator or Owner/Global Administrator role to customize the filtering policies to suit your school's specific requirements. You can learn more about creating effective filtering policies using Categories, Subcategories, and Signatures in our guide.

We regularly review and update each Category, Subcategory, and Signature to ensure websites are accurately classified. If you think a website has been misclassified, please contact the Linewize Support Team.
