School bells will ring this morning for the first time in 2021, welcoming 275,000 South Australian students in to class.
This includes about 13,000 reception students attending public school for the very first time, and about 13,000 year 12 students entering their final stage of their schooling in government schools.
Some non-government schools return Monday next week.
It will also be the final year of primary school for a double cohort of public school students, with 29,000 year 6 and 7 students saying goodbye to primary schooling at the end of the year as they move into high school from 2022.
Education Minister John Gardner believes 2021 is set to be a great year.
"This is a time of great excitement and optimism for students and educators alike and I would like to wish them all the very best for the year ahead," Minister Gardner said.
"The 2021 school year is sure to have its challenges, but I am confident that our students will show the same resilience and determination that impressed us all last year.
"Whatever is thrown at us in 2021 I know our students can handle it with the support of our great educators across the state.
He reassured parents and guardians of children starting school for the first time that the early primary teachers are "extremely skilled", meaning a smooth transition into school life.
"Significantly, this year will be the last year of primary school for a double cohort of students, with our year 6 and 7 students both transitioning into high school in 2022.
Furthermore, the $1.3 billion build to accommodate the change is in full swing, with more than 70 projects now under construction and more set to begin in the coming months.
The projects are expected to create thousands of jobs across the state and provide a critical boost to the state's economy.
"We are working hard to continue our improvement trajectory in education as we continue to deliver our commitment to supporting our schools to achieve growth for every child, in every class, in every school," he said.
Adding that he thanked every educator and support staff in school for the valued work they do. "...I am looking forward to a great year ahead".
