High school students were taught the wrong maths curriculum.

NSW’s education minister is “furious” a rural NSW high school has taught senior students the wrong maths lessons for the past eight months.

Year 11 students at Coonamble High School in the state’s central western plains have reportedly been taught the incorrect Mathematics General syllabus since the beginning of the year.

The school’s principal and a representative from the Department of Education met on Tuesday night to discuss a solution and reportedly advised students to do their best in the upcoming final exams.

NSW Education Minister Rob Stokes said he was absolutely appalled by the oversight and said the solution was not acceptable.

“I’m angry on their behalf, if this was my child I would be furious,” he told 2GB Radio on Wednesday.

“What the school has come up with, in my view, is not acceptable.

“One of the solutions offered (at Tuesday’s meeting) was if they don’t do well they can do it again next year. That’s clearly a laughable solution.”

The results from Year 11 do not directly affect a student’s HSC or ATAR mark but the lessons provide a necessary foundation for the final year of schooling, AAP understands.

Mr Stokes said he has instructed a representative of the Education Standards Authority to visit Coonamble High School and find a solution to ensure the students are not disadvantaged.

“I’ve made it clear that I want disciplinary matters looked into,” he added.

The minister said he was “appalled”.

“This is not good enough, my heart goes out to the students and their parents. I’m angry on their behalf,” he said.

It was suggested students cram before and after school for the next eight weeks to learn the correct maths curriculum before the next exam.

2GB’s Ray Hadley said the six students affected and their parents were distressed.

“They had a meeting yesterday with the NSW schools director and the school principal,” he said.

“The only solution for them was to study before and after school for the next eight weeks to cram for the exam.

“Now we’re talking about 16 and 17-year-old children being put under pressure an adult couldn’t deal with.

“It’s not fair, I don’t know what the answer is, you can’t just say do you best the next couple of months and if you fail well chewy on your boot.”

Mr Stokes said he agreed and the solution the school arrived at was not acceptable.

He said somebody from the Education Standards Authority would be sent out to the school to determine the best way to support students and ensure they’re not disadvantaged.

“The system has failed these students and we need to make it up to them,” he said.

The Department of Education has been contacted for comment.
