The Shire of Toodyay has topped the region as the 'most advantaged' location for educational possibilities, despite ranking poorly compared to the rest of the state.
A new interactive tool launched by Teach For Australia revealed schools within the Shire's postcodes placed 74th overall for study opportunities, out of 139 areas in Western Australia.
The Shire of Beverley came in second place in the region at 103rd in the state, closely followed by the Shire of York which ranked 105th.
Both were labelled 'disadvantaged' when it comes to students' educational possibilities, compared to the rest WA.
The Shire of Northam was labelled 'most disadvantaged' in the region, sitting at 108th overall.
The research was compiled using a number of indicators of educational disadvantage, including qualifications post-schooling and NAPLAN performance, to produce a map of postcode rankings.
The data also revealed, by age 15, Australian children from the lowest socio-economic households were, on average, almost three years behind in school than children from the highest socio-economic households.
Teach For Australia founder and chief executive Melodie Potts Rosevear said a postcode "shouldn't define a child's future".
"Children from both metropolitan and rural areas deserve to be able to achieve their potential," she said.
"At Teach For Australia, we are working hard with a number of different stakeholders to ensure that all children achieve their potential, regardless of their postcode."
Ms Potts Rosevear said it was time for something to be done to tackle educational disadvantage.
"For decades, student outcomes on average have not improved. This is a systemic problem, with no one group responsible, but the consequences are dire for our children and our country's future," she said.
A Teach For Australia spokesman said the non-profit organisation was working hard to achieve accessible quality education for all Australian children.
"There's so much we can and must do and we think that for Australia to achieve an excellent and equitable system, we need to attract top talent into teaching, provide instructional coaches to early-career teachers, tailor professional learning to teacher contexts and foster collaboration and community in the teaching profession, among other things," he said.
"No one person or institution will be able to amass the changes required, but a group of committed actors across our system can and that is what we hope to generate."
A WA Department of Education spokeswoman said the state government would continue to work alongside the non-profit organisation to obtain the best results for students.
"We work with Teach for Australia and have for some years," she said.
"WA public school students have access to the same learning opportunities, regardless of where they live, and follow the same WA curriculum.
"We have options for students who may not have access to some courses because they are travelling or live remotely or if the school they are enrolled in may not offer a particular course."
