Highland councillors have been asked to approve plans for a new £44m school campus in Tain in Easter Ross.
Children aged from three to 18 would receive nursery and school education in new buildings proposed for the site of the current Tain Royal Academy.
Once completed Knockbreck Primary, Craighill Primary and St Duthus special school would be closed.
Some responses to public consultation on the plans raised concerns about having pupils of all ages on one site.
Council officers said the project would deliver considerable educational benefits for pupils, including access to a Gaelic medium education unit.
Councillors will discuss the project at a meeting on 11 February.
