But parents will have to wait until next month to see what may be in store for them.

Maps will be provided to all public school principals highlighting their school and the revised boundary, detailed to specific streets.

Principals in the North- West met Education Department officials yesterday.

Those in the South will meet the department tomorrow.

Principals will leave today's meeting with a copy of the proposed revised out-of- home area guidelines and a map that has been determined using data taken from the Australian Bureau of Statistics.

The out-of-home area changes would come into effect from 2015.

"There's a really clear set of criteria that are used to help make a decision about whether that (child is) a good fit or not," one principal said.

"We need to be really clear and transparent as to how we look at each (child).

"However, no one is going to be making any parent go to a school that they don't want to."

Education Minister Nick McKim said under the School Viability Reference Group it was found that policies relating to catchment areas and school boundaries were outdated and interpreted in different ways by schools, parents and the public.

"The new draft procedures have been developed to ensure that there is a consistent statewide approach to dealing with enrolments of out-of-home area students," Mr McKim said.

The government valued the input of schools to develop and refine the policy, he said.

Following feedback from principals, necessary adjustments would be made.

After that, the information would be available to the broader school community through school associations by June 12.

Principals will then have until the end of August to consult their school community.

It is understood that since third term last year, principals have been asked to tighten the out-of-home area guidelines at their schools.

The guidelines have not been revised in nine years.
