The Australian Christian Lobby is gauging whether its supporters think the national curriculum ignores Christianity's role in shaping Australia.
Australian Christians are giving their opinion on religion in schools in a survey to inform submissions to the national curriculum review.
The Australian Christian Lobby wants the national curriculum to adequately cover religion and Christianity in particular.
"ACL is currently surveying its supporters to understand their perspectives on the national curriculum to help form its submission to the review," managing director Lyle Shelton told AAP in a statement.
The ACL believed an understanding of Christianity was vital for students to understand modern Australia and western civilisation, he said.
Its survey asks people how strongly they agree or disagree with nine statements, including that the current curriculum doesn't pay close enough attention to Christianity and its contribution to Australia's history.
It floats the idea that religious schools be allowed to teach students creation theories along with evolution and suggests the curriculum's focus on sustainability, indigenous and Asian themes come at the expense of other important areas.
People are also asked whether they agree that "our dating system hinges on the life of Jesus Christ" and want the terms Before Christ (BC) and Anno Domini (AD) retained.
The Australian Curriculum and Reporting Authority clarified more than two years ago that there was no intention to drop the terms BC and AD from history classrooms.
The ACL's website encourages its supporters to make their own submissions to the curriculum review.
It also highlights an opinion piece reviewer Kevin Donnelly wrote in which he said students are "forced to learn every subject through a politically correct prism" that ignored Australia's Judeo-Christian heritage.
