Chromebooks will be filtered at home in the same way they are at school. Sites that are blocked at school will also be blocked on Chromebooks at home. All filters inherently have holes; the best filter is teaching students to be safe and smart online coupled with appropriate supervision by adults.

It is possible for parents to set up an additional filter to limit more websites at home.  Setting an additional filter will not enable parents to unblock sites blocked by the school filter through the Chromebook.  If you are interested in this option, check with your Internet provider for options or use a third party tool such as OpenDNS.  Both free and paid options are available.
