Parents, Here's The First Day Back At School Info You Need

It will be a year of firsts -- and lasts - for thousands of students in New South Wales and Queensland who are heading back to school this week. 

Some of the 810,000 students in NSW will be greeted with new classrooms and air conditioning as they start school in 2019.

Eight new and nine renovated public schools will open for the first time, providing an extra 400 classrooms capable of housing thousands of students.

It's part of the NSW government's $6 billion education infrastructure blitz, with 170 schools to be built or revamped over four years.

NSW Education Minister Rob Stokes said the coalition is responding to a "once-in-a-generation opportunity" to provide the facilities students need to succeed.

The government is spending $847 million on school maintenance and $500 million on air conditioning.

Two new schools have been built for students with disabilities in Dubbo and Narellan while a 60-room high school has been built in Ballina on the NSW north coast.

Sydney's Manly Vale Public School received a 40-room upgrade while a 30-room senior campus has been built at Cammeraygal High School in Crows Nest.

It's the largest education infrastructure spend in the state's history, Stokes said.

About 88,000 staff, including 900 new teachers, have been hard at work preparing for new classes in core subjects under a revamped syllabus first rolled out in 2018.

Year 12 students will be NSW's first class to take their final exams in the new English, maths, science and history subjects.

Students will also be allowed to graduate with an Australia Tertiary Admission Rank, or ATAR, by taking the easier English Studies course which was formerly a non-ATAR unit.

It's the final step in a curriculum overhaul begun in 2017.

The education department will be hoping for a smooth start to the year after the government was forced to apologise for putting the wrong date on the official certificates of students who completed their HSC in 2018.

Tuesday is the first official day of the school year, with most students returning to class during the week.

In Queensland, some 66,000 preppies about to take their initial steps into the education system.

Schoolgirls can now wear shorts or pants thanks to an overhaul of state uniform policy.

There will also be firsts for thousands of Year 11 students who will be the first to study new subjects, sit external exams in Year 12 and graduate with an Australian Tertiary Admission Rank (ATAR).

The Year 12s also make history as Queensland's first ever prep class in 2007 to graduate as the last group to sit the Queensland Core Skills Test and the last to receive an OP.

Education Minister Grace Grace said more than 560,000 students would attend 1241 state schools and 270,000 students in 515 non-state schools.

State schools will welcome 47,000 youngsters into prep, with numbers on-par with previous years.

Independent Schools Queensland (ISQ) Executive Director David Robertson said among the students enrolling at the state's 240 independent schools in 2019 were about 7400 new Prep students, and more than 12,000 Year 7s entering high schools.

"2019 is a milestone year for Queensland schooling with historic changes to the state's senior assessment and tertiary entrance systems commencing," Robertson said.

Principals, teachers and other school staff have been hard at work preparing their education programs and classrooms ahead of the first school bell, while parents have been busy finalising stationery, uniforms and family schedules.

Queensland Independent Schools Parents Network Executive Officer Sue Kloeden said establishing positive routines early was important for students and parents.

"I encourage parents to talk with their schools about how best to help their children settle in, particularly prep students and those who are new to a school," Kloeden said.

The majority of Queensland schools will start the new school year on Tuesday.
