Web Content Filtering in LPS

Federal Regulations

In order for the district to receive ERate funding that reduces the cost of our Internet access by by a large percentage, Federal regulations require compliance with guidelines provided in the ‘Children’s Internet Protection Act’ [47 U.S.C. § 254], also known as CIPA. CIPA guidelines require the restriction of access to specific types of web content.

Based upon CIPA guidelines, LPS employs a web content filter that blocks access to the following categories of web pages for all users:

  • Gambling
  • Pornography
  • Anonymous Proxies (Sites that allow for circumventing of web filters)

Role Based Authentication


Example of the “block page.”

While you are on the LPS network if you attempt to load a web page that is restricted for students, you may notice a login & password field appear on the block page. LPS employees may enter their LPS credentials to access any web page not contained in the CIPA block list. This is known as “Role Based Authentication” and respects an educator’s right to make professional decisions about the content accessed.

By logging in with your LPS username and password to access content that is blocked from student view, you are offering a digital “signature” that you accept responsibility for the content you are accessing and acknowledge the content is consistent with the educational mission of Lincoln Public Schools. This is neither a “bypass” nor “override” of the filter but, rather, it is access granted to adult educators and this access should not be used to provision access to students.

When you login to the filter a small pop-up window will appear and as long as this window is present, you are able to access restricted content. All of the URLs (web addresses) accessed while this pop-up window is open are logged in the filter software.

Example of the authorization window.

It is not appropriate, and would be a direct violation of LPS Regulations, for teachers or other employees to either log in to the filter and allow students to gain access to content that would otherwise be restricted, or give students your user name and password for this purpose. LPS Instructional Policy 6441 specifically states that disciplinary action (including expulsion or dismissal) may result from inappropriate use of computer technology or networks.
