The peak body brings together 15 Christian groups, as well as Queensland representatives from the Islamic, Jewish, Baha'i and Buddhist faiths, under the name Multi-Faiths RI Peak Body.

The body said its aim was to ensure people in years 1 to 12 in Queensland state schools were given the opportunity to question and explore faith, values and their cultural expression in a safe and supportive environment.

Religious instruction (RI) is available at 746 state schools, with principals required to approve each curriculum before approving it in their school in 2019.

Uniting Church in Australia Queensland synod moderator Reverend David Baker said the body had begun a review of RI curricula to be used in state schools next year.

"The review is designed to ensure that in 2019, Queensland schools have best practice curriculum for every parent who chooses to have their child attend religious instruction," he said.

The review will ensure compliance with education legislation and policy.

It will be conducted by Australian experts and overseen by Professor Zehavit Gross, a UNESCO chair from Israel, and panel members Emeritus Professor Suzanne D Rutland and Kate Bertram from Bertram Research and Development.

Islamic Council of Queensland spokesman Ali Kadria said the body wanted to reduce the workload and operational pressures faced by principals.

"The multi-faiths group has made representations to the minister and the department to advise them about the new peak body and the curricula best practice review," he said.

The review is being conducted independently of Education Queensland with the results to be presented to the department for its consideration.

Last year, Education Queensland's religious instruction report was reviewed following a furore that resulted in Christian groups pitted against the Palaszczuk government over claims students were barred from talking about religion at school.

Former education minister Kate Jones was forced to release a statement insisting there was no change to RI policies after reports students were banned from referencing Jesus in the schoolyard.

Ms Jones said nobody was telling a child what they could and could not say in the playground.

Last year, about 23 per cent of state school students participated in RI programs.

A review of RI materials found the lessons included taking a group to a grassed area to play a game of "slave tag", where the teacher would say: "Joseph was sold as a slave. Slaves were dragged around until sold to a master."

The game of tag included a "slave trader", who tipped a person who became a "slave" and had to link arms with the "slave trader", who then both chased after other "slaves".

The reviewers said playing a game of "slaves" was not appropriate in RI classes.
