La Salle Catholic College, Bankstown and Holy Spirit College, Lakemba in Sydney are among an elite group of secondary schools that have been recognised by a national assessment body for their outstanding work in improving student results.
The findings were made public in a report released by the Australian Curriculum, Assessment and Reporting Authority (ACARA).
The report focused specifically on student performance in literacy and numeracy, based on the 2015 National Program in Literacy and Numeracy (NAPLAN) examinations.
La Salle College Bankstown and Holy Spirit College Lakemba were among only 79 out of 10 thousand schools around the country that were recognised by ACARA for having achieved learning improvements, deemed to be "substantially above average".
La Salle Catholic College Bankstown was recognised for outstanding improvements in the area of numeracy, while Holy Spirit College Lakemba was recognised for outstanding improvements in literacy.
The Principal of Holy Spirit College, Lakemba, Phillip Scollard says the results are a credit to students and staff at the school.
"Giving students the opportunity to know more, to do more and to be more is what we are about here at Holy Spirit", he explained.
"This is also something for our parent community to celebrate as they are also a critical part of their child's learning journey".
The Leader of Learning at La Salle College Bankstown, David Cloran says the results are extremely encouraging.
"I extend our deepest congratulations to all students and teachers who have contributed to not only this fantastic recognition, but also for their ongoing contribution to such a wonderful culture of academic success here at the school", he said.
