Urrbrae Agricultural High School assistant principal Dean Cresswell believes the change can be attributed to pressure and lobbying by the Primary Industries Education Foundation and a number of other agricultural providers.

"It's great news for us," he said.

"I'm tickled pink – it's thanks to these people and support from the media, such as Stock Journal, that this has happened."

Only two months ago, Mr Cresswell, who is a member of the South Australian chapter of the PIEF, said he received a letter that indicated agriculture would not be included in the national curriculum.

At the time, he said the exclusion would lead to "the death" of agriculture as a subject because schools would choose to offer nationally-recognised subjects instead.

Mr Cresswell said he found out about the change two weeks ago, after PIEF chief executive Ben Stockwin visited teachers in SA.

The change means that agriculture will be taught to children from kindergarten to Year 8.

Mr Cresswell said agriculture would be included as a theme, not a subject, in the curriculum for these students.

He was also hopeful that it would be taught as a stand alone subject in Years 7 to 12.

"It gives agricultural education a real boost," he said.

"It'll also help support rural communities."
