Google: YouTube for Schools

The steps below show network administrators how to configure access to educational and school-appropriate content on YouTube.

1.  SIGN UP for a school account
Start by signing up for an official account for your school by visiting this page. The administrator of this account will then have the ability to include videos of his/her choosing for viewing within the school network. The administrator will also be able to approve access for teacher accounts


2.  CHOOSE ONE OF THE FOLLOWING Options Depending On Your School's Network

A)  Add new HTTP header rule
Modify your hardware filter or proxy server settings so that all outgoing traffic to youtube.com contains the following custom HTTP header. The ID to use in the HTTP header configuration, written below, is an example of a unique ID for your school’s network only. If your school is blocked at the district level, this HTTP header is then unique to the district network.

Example:
X-YouTube-Edu-Filter:ABCD1234567890abcdef
Field Name: X-YouTube-Edu-Filter
Description: When YouTube sees this header and an accompanying valid school ID in the incoming traffic, YouTube will serve a limited EDU-only site to all computers behind the school hardware filter.
Field Value Format: alphanumeric [a-z][A-Z][0-9]
Field Value Length: up to 44 characters

B)  Create URL parameter rewrite rule
If your hardware filter does not support HTTP header modification, please rewrite all outgoing URLs to youtube.com by appending the parameter “edufilter” at the end. Exclude the &edufilter parameter from these file types: .css, .gif, .png, .js, .xml

Example:
http://youtube.com/?edufilter=ABCD1234567890abcdef
http://youtube.com/watch?v=gM95HHI4gLk&edufilter=ABCD1234567890afbcdef


3.  REMOVE YouTube Domains Blocked
Ensure the following top-level domains are not blocked:
youtube.com
ytimg.com
