Four secondaries, including Banchory Academy, part of the national pilot trumpeted as a success, are having their funds withdrawn and there is now little hope of extending the scheme.
A teacher spokesman commented: "This is a kick in the teeth to people involved in extracurricular activities."
The spokesman added: "The school sports co-ordinators have rejuvenated inter-school competition and we are concerned that this will now fall by the wayside."
A council spokesman said: "We had hoped to extend the scheme across Aberdeenshire, but that now looks unlikely in the current financial climate."
It is investigating sponsorship as a way of sustaining developments at Ellon, Mintlaw, Portlethen and Banchory.
Meanwhile, a high-profile launch in East Ayrshire was praised by Sportscotland for its leadership from the top.
Stewart Harris, head of youth sport, said: "It is not only co-ordination within a school which is important. It is also required at education department level and East Ayrshire has set a good example by appointing an education officer to manage the team of co-ordinators, with further input from the community services department."
