Gaelic goes on the signs in Highland
Total immersion in Gaelic will be introduced as fully as possible in dual language schools.
Highland's initiative is designed to step up pressure on Scottish Executive ministers to grant equal status to the language in a number of other areas.
Donald Macdonald, head of education, said: "It is important to provide cultural and language opportunities in communities so that children can have a context for using the language.
"It is important they see Gaelic on road signs, in shops and other places, as well as in the media, and that will give the language a greater chance of becoming part of community life."
