Why are some websites blocked at school?

Privacy and safety

Schools protect student information. Some websites collect data like names or email addresses. Before a site can be used in class, the district checks it and signs an agreement that limits how the site can use student data.

What is SB29‑guard?

It’s a tool that shows a clear message when a blocked site is opened. Instead of just saying “blocked,” it explains why and what to do next. It helps teachers and students understand the process.

What should I do if I see the page?

• Ask your teacher if you need the site for class.
• Your teacher can request that the district review the site.
• Use an approved alternative if one is available.

Learn a bit of the tech

When you visit a website, your browser asks the site’s server for a page. Schools can route that request through a gateway (a kind of helper) that checks if the site is approved. If it’s not, you’ll be redirected to the explanation page you saw.
