Classroom Manager Rules FAQ

This topic answers common questions about Rules and provides troubleshooting advice for common problems.

About Classroom Manager Rules

How do Classroom Manager Rules work?

• Classroom Manager Rules are a temporary overrides of your school’s day-to-day content filtering policies.
• You can use Allow Rules to let students in your class access websites that would otherwise be blocked by your school’s content filtering policies.
• You can use Block Rules to stop students from accessing resources during your class that may be disruptive or off-topic.
• You can use Block Rules to stop students from opening certain applications on their Windows devices during class.

Do Classroom Manager Rules work across all of my classes?

No. If you set a rule for one of your classes, it will be saved for that class only and applied each time the class runs. The rule will not apply to any other classes you have.

For example, your school’s filter may normally block students from accessing YouTube. If you wanted students in your first class of the day to access YouTube to support their learning, you could create an "Allow YouTube" rule in that class. The students in this class will be able to access YouTube until the class ends or you delete the rule, whichever happens first. None of your other classes would be able to access YouTube unless you also created an Allow rule for them.

Do Block Rules block both desktop and browser versions of apps?

Yes, a Block rule will block access to both web and Windows desktop versions of an app. Here’s how it works:

Rules for Signatures

Rules for Signatures will apply to both the web and, on Windows devices, desktop versions. For example, adding a Blocked Rule for the Spotify signature will block both the Spotify desktop app for Windows and the Spotify Web Player. 

See How Classroom Manager Rules Work for more information about Themes and Signatures. 

Rules for desktop applications (Windows only)

You can add Block Rules for some Windows applications that don’t have a web component, such as Paint, Solitaire, Notepad, Adobe Reader, VLC Media Player or Firefox. See the list of compatible Windows applications on this page.

Can I add rules for URLs?

You cannot block or allow individual pages on a website or signature. When adding a rule for a URL, it automatically applies to the entire domain. The same principle applies to YouTube videos. If a Classroom Manager rule blocks YouTube, you cannot add a rule to allow an individual YouTube video. See: Adding, Editing and Removing Classroom Manager Rules.

How quickly do Classroom Manager Rules take effect?

New Rules will start working immediately. However, what happens on your students’ side will differ depending on which version of Linewize Connect is installed on their device.

For Chrome

• If a student is currently on a page you want to block, turning on a Block rule will immediately kick the student off that page. The tab will close, and the student will get a message on their screen telling them you closed a tab.
• If they attempt to open a site with a Block rule, they will be blocked from opening the page, and the “Content Blocked” notification will appear on their browser immediately. To access the blocked site, the student can select See why it’s blocked and ask you for a Bypass Code (Chrome only).

For Windows, macOS, or devices without Connect installed

• The student can still access the blocked website until they go to another page or reload the one they are currently viewing. This is due to caching, which allows browsers to save temporary files for quicker loading the next time the user opens a web page.
  Streaming videos will not close immediately, but buffering or loading will stop eventually as the new rule takes effect.

For desktop apps (Connect for Windows only)

Rules for desktop apps will take effect depending on when you created them.

Before the rules take effect at the start of the class, while the app is open on the student’s device or when they wake up their device from hibernation, they will receive a prompt that tells them the app will close in 60 seconds.

Can I create rules even if the class isn’t in session?

Yes! Setting up base rules for a class before it starts is good practice. However, remember that the rules you make for a class only apply to that class and only take effect while the class is active.

Rule Validation

Rules Validation helps you create effective Class Rules by checking for duplicate or conflicting rules.

Does Classroom Manager test if my rule is valid?

Yes, Classroom Manager always checks to ensure your rules will work as expected and prevents you from creating rules that won’t work.

I want to add a rule for a site, but it conflicts with a Locked policy in Linewize Filter. What should I do?

Contact your school’s IT support staff to discuss unlocking the filtering policy. Find out more about Locked policies here.

Can I exempt categories and signatures from the rules for their parent themes or categories?

Yes, you can exempt child categories and signatures by adding them first. Delete the existing rule for the theme if you’re exempting a child category, or the rule for the category if you’re exempting a signature. Next, add the rule that exempts the signature or category, then add again the rule you’ve just deleted.

Do rules created in Linewize Filter affect both web and desktop versions of applications?

Rules created in Linewize Filter only affect the web versions of applications and not their desktop versions. For example, a Locked-Blocked rule in Linewize Filter for Outlook will only block access to Outlook.com, not the Microsoft Outlook application installed in the student’s Windows device.

To block both web and desktop versions of Outlook, add a Blocked rule in Classroom Manager.

Can I check if a rule I created works before my class starts?

Yes! You can create rules and check if they work before your class starts. Any rules that you create will still be validated.

Rules Troubleshooting

I made an Allow Rule, but the site is not working properly or looks wrong.

This can happen when you’ve made a rule allowing a specific domain, subdomain, or page, and it needs to get data from blocked sites. Try to create the rule at the signature level instead. Creating a Rule on the Signature will ensure the site and all other sites it needs to work on will be unblocked.

For example, if you allow the domain powerschool.com while videos from Vimeo.com are blocked, the site will not show the embedded videos. However, if you allow the “Power Schools Learning” signature instead, the videos from Vimeo would appear because the signature includes everything Power Schools Learning needs to work, including embedded videos. Allowed sites or pages can still load on students’ browsers, but embedded content, such as videos from blocked sites, will appear as Blocked frames within allowed sites.

I’ve made an Allow Rule for a YouTube video, but students are restricted from viewing the video.

If you've encountered restrictions on students viewing a YouTube video despite adding a rule, it's likely due to your school’s YouTube SafeSearch settings. Contact your school’s IT support staff to discuss adjusting these settings and ensure that students can access the content as intended.

I’ve made a Block Rule, but my students can still access the site.

You may have an Allow rule that applies to only some students. If you create a rule to Block YouTube for the whole class and then create a second rule that allows it for some students from the same class, these students will still be able to access YouTube.

Fig 3. A Blocked rule for the Arts and Entertainment Theme applies to the whole class except Adrian Fischer and Danielle Bernard.
