Over 13,000 schoolchildren have taken part in Show Racism the Red Card's schools programme since it was launched in Perth and Kinross 15 years ago.
It is the longest running partnership between the anti-racism charity and a local authority in Scotland.
The programme has been delivered for 15 consecutive years, including four virtual workshops during the Coronavirus lockdown in 2020/21.
In Perth and Kinross it is delivered by Saints Community Trust staff who have been trained by the Show Racism the Red Card Education team.
On Monday, representatives from Show Racism the Red Card and Saints Community Trust were presented with certificates to mark the long-running partnership at the Council Chambers at 2 High Street, Perth.
Learning and Families convenor Councillor John Rebbeck said: "It is disappointing that organisations like Show Racism the Red Card are still required but, having attended sessions myself, it is a fantastic programme and explains the harm discrimination of any kind can cause.
"These attitudes have no place in our society but sadly are still prevalent and that is why programmes like Show Racism the Red Card continue to be necessary.
"To have reached more than 13,000 young people is a tremendous achievement and I would like to thank Saints in the Community and Show Racism the Red Card for all their work."
Perth and Kinross Council's equalities lead Councillor Peter Barrett added: "Discrimination is abhorrent in all its forms and the preventative work Show Racism the Red Card does in our schools is invaluable.
"It challenges children and young people to consider discrimination and what to do when they encounter it."
