A $4.5 million special education unit will be built at the Ceduna Area School, on South Australia's west coast, with the state government describing it as vital support to the regional community.
The school caters for 420 students, with more than 10 per cent identified as having special needs.
"Inclusive education and every child's right to a quality education, is an extremely important part of my agenda," Education Minister Blair Boyer said as he visited the school on Monday.
"It's vital we continue to support those in our school community with special needs, so they have the facilities, programs and opportunities needed to flourish."
The new unit will also free up the library facility for wider community use.
The special education unit's two classes currently share a building with the community library.
School principal Andrew Gravestocks said local families, students and the community needed to have equal access to high quality education facilities and programs, including those with additional needs.
"Having an inclusive environment is important to our school community," he said.
"The opportunity to ensure the public library and special education programs flourish is essential for our children, educators and wider community."
