mLISD Filtering FAQ

 Internet Filtering

Why does Leander ISD filter internet traffic?

Under the Children’s Internet Protection Act (CIPA), Leander ISD is responsible for implementing technology measures or internet filters to restrict access to sites that are “harmful to minors.”

For any questions or comments on the District's policy, please visit Let's Talk.

What kind of content is blocked by the District filter?

The District blocks various categories of content for students including, but not limited to, the following examples:

  • Adult Content
  • Alcohol / Drugs
  • Movie/Music Sites (Netflix, Pandora)
  • Gambling
  • Games
  • Social Networking (Twitter allowed)
  • Hacking or Unlawful Activities

New internet sites come online every day and no filter is perfect, but all categories are updated continuously as identified by the filter vendor.

Filtering is not a perfect science and occasionally sites can be miscategorized and inadvertently blocked or open for various reasons.    Parents should continue to monitor students device usage and contact the Technology department should any sites need further evaluation. 


Why are some sites that don't seem harmful blocked?  

Leander ISD has limited technology resources and internet bandwidth. These resources are prioritized for services like Google Classroom and other instructional services. For this reason, some categories of content like Streaming Audio/Video which consume these resources but are not necessarily instructional may be blocked.


Why are some of my search results blocked?

Sometimes, especially with image searches, you may notice that various search results are filtered out even though there was nothing inappropriate in the search terms.

In these cases, the filtered results are hosted on sites which contain both appropriate and inappropriate content. Consequently, all content on those sites is blocked.

In these cases, please remember that Google is not the only place for conducting research. Campus librarians can provide numerous additional resources for research needs.

A great place to start is the TexQuest Resource Guide. For even more resources, see your campus librarian.   Click here for links to LISD Campus Libraries. 

What can I do if an instructional website is blocked?

  1. Submit a Website Review Request from the blocked page.
    This will be the quickest and easiest way to request a website review in almost all cases. Staff and students have different blocked pages and therefore slightly different links to submit a website review request.

    Staff - Simply click the "Submit URL" button and enter any additional information desired at the prompt.

    Students - Simply click the "Website Review Request" link, and enter the required information in the form.

    An incident will be created, and the user will be notified upon completion.

  2. Submit a Website Review Request from (staff only).
    1. This option is available if there is no blocked page. For example, an instructor submitting a request for a website blocked only for students.

    2. On the Service Manager website, navigate to Network and Internet/Website Review Request, and provide request details.

    3. All other details are the same as using the "Submit URL" button.

  3. Contact a Technology facilitator or the ITS Help Desk (staff only).
    Campus Facilitators and the Help Desk can unblock websites. ITS Help Desk is available at 512-570-0517.

Why is a website blocked and showing "Policy=default"?

Internet content is filtered based on your identity. This explains why instructors have more access than high school students who have more access than elementary school students and so forth. If the content filter does not know who you are, you will be filtered under the most restrictive or “default” policy as shown on the block page.

This can happen if you have not logged in to your computer for a while or for a variety of other less common reasons. To re-establish your identity for the most accurate filtering, try any of the following:

  • Click the link to and then close the resulting window. You may then be able to immediately begin browsing as expected.
  • Logoff/logon to your computer
  • Reboot your computer

What can I do if I'm having trouble accessing the internet at home?

  1. All student devices have CKMobile software installed, which enforces District content filtering, whether inside or outside the District.

  2. When inside the District, the network icon shown in the Task Bar is the normal "wireless" icon.

  3. When outside the District, the network icon shown in the Taskbar is the "wired" icon and reports "" when the mouse hovers it.

    A screenshot of the icon.
  4. It may take up to one minute for the connection to come up outside the District. If you have any difficulty with internet connectivity after this time, try any of the following:
    1. Close and reopen your browser.
    2. Turn WiFi off and back on.
    3. Restart the computer.

If unresolvable issues prevent internet connectivity outside the District, go to (on another computer) and submit an Off Site Filtering service request for District support.

How does Leander ISD filter YouTube?

The District uses Strict Restricted YouTube access for all students. This is the most restrictive setting YouTube offers. Many videos are screened out automatically and instructors must approve other videos to be used for instruction.

Why can't I print to a network printer at home?

The district filter creates a secure tunnel over the internet back to the Leander ISD network. So in effect, a district device never leaves the district network, which is why resources on other networks are not accessible. To print your work, we recommend one of the following:

  1. Connect your device to your home printer using a USB cable.  In many cases, the computer will already have a driver for your printer.

  2. If you can't make a direct connection to your printer, save your work and print it out at school on the following day.


How can instructors be sure that class material won’t be filtered for students? 

Confirming student access to web content before planned instruction is always advisable. Student access can be verified as follows:

  1. Open a Chrome browser incognito window.
    (This is necessary to prevent false positives/negatives related to website caching.)

  2.  Perform all remaining steps in the incognito window that opens.

  3. Go to a site that will produce a blocked page such as, and click the "Login" button.

  4. Login with the username "studenths", "studentms", or "studentes" depending on your grade level and the password will be the same as your username.

  5. Click the "Continue" button after logging in as a student.

  6. A "Login Successful" window will pop out, indicating you are now filtered as a student. Be sure to leave this pop up open.

  7. To return to staff filtering, click the "Logout" button in the pop out window.
    1. Do not close the pop up window by clicking the X in the upper right corner.
    2. If you do accidentally click the X, you will have to type "" into your browser address bar and hit Enter to return to staff filtering.
