There have been more than 550 serious assaults on New South Wales teachers during the five years 2012-2016.
Some of the violent attacks have been the result of "angry parent syndrome".
Teachers have suffered burns, abrasions, concussions, open wounds, crushing, internal injuries, dislocations, fractures and psychological disorders.
During 2012 there were 101 assaults on NSW teachers, 64 requiring medical treatment.
During 2013 there were 127 assaults on NSW teachers, 88 requiring medical treatment.
During 2014 there were 81 assaults on NSW teachers, 47 requiring medical treatment.
During 2015 there were 168 assaults on NSW teachers, 103 requiring medical treatment.
During 2016 (figures to November 3) there were 75 assaults on NSW teachers, 34 requiring medical treatment.
The New South Wales Education Department recorded 502 violent incidents at schools during the first half of 2016, affecting students and teachers.
One teacher suffered a chipped tooth when a student smashed a computer monitor over her head.
NSW teachers are granted provisional accreditation to teach after they leave university.
Teachers working full-time have three years to gain full accreditation.
If they work part-time or casual they then have five years to meet the requirements.
Teachers who fail to meet the requirements for full accreditation can no longer apply for registration to teach in public or private schools.
They have to re-start their degree.
In 2015 521 NSW trainee teachers failed requirements of the new national accreditation system , mainly because they could not find sufficient work within a three-to-five year period. (Figures from the New South Wales Board of Studies.)
These 521 teachers are now ineligible to teach without restarting a new degree.
This suggests that since 2010 at least $130 million in taxpayers' money could have been spent at universities to train graduates whose degrees had gone to waste.
The problem seems to be that there is a glut of teachers looking for work in NSW, especially in particular teaching fields.
Up to 40 per cent of teaching graduates are not able to find work within four months of graduation.
Many trainee teachers are unable to satisfy the requirement to work 160 to 180 days within a three-to-five year period.
Many trainee teachers also work as casual teachers, so they never get the opportunity to prepare documentation like lesson plans or take part in professional development - and these form a major part of the accreditation requirements.
The New South Wales government's Early Action for Success program is an example of extra funding having little effect on student achievement when the most effective teaching methods are not being used in classrooms.
The Early Action for Success central literacy program was called L3.
L3 was not properly trialled and tested before being implemented in more than 400 schools across NSW.
L3 does not meet the criteria for evidence-based reading instruction identified in scientific research, including an absence of systematic phonics instruction.
44,000 teachers are waiting for a permanent teaching position with the New South Wales Department of Education.
The Department warns that by 2021 there will be a "more than adequate supply of primary teachers in all geographical locations" and an "adequate supply of secondary teachers".
Australian has a worsening oversupply of teachers - but Britain is struggling to meet the demand for teachers.
Shahrzad Amjadi, University of Notre Dame teaching graduate, only had to wait a matter of days between finishing her final teaching placement and being offered a full-time job at Heathrow Primary School, a government school west of London.
"I am really excited because I love the sound of the school and I got along really well with the principal in the interview and he really seemed to have a vision for the school so I think it is going to be a great experience for me", Ms Amjadi said.
Mitch Jones, an international education consultant working for Protocol Education Australia, said the demand for Australian teachers was now much higher as Britain battles with a shortage of teachers.
Badapplebullies editor comments : I have no commercial relationship with Protocol Education Australia or with any other organisation mentioned on this website.
But I have worked in England.
I think this is a really good option for young Australian teachers.
Shahrzad will have amazing travel opportunities.
And her social life will will so much better than that of an Australian teacher stuck out in some remote community.
UK Schools snapping up NSW teaching graduates, Alexandra Smith, Sydney Morning Herald, 27 December 2015
New South Wales Education Minister Adrian Piccoli revealed that NSW state schools had given full-time teaching jobs to only 527 of NSW's 8361 education graduates.

Teacher glut hits university graduates' job hopes, Natasha Bita, The Australian, 12 October 2015
In October 2014 there were 44,000 New South Wales education graduates languishing on waiting lists -
25,374 NSW education graduates were waiting for a full-time job as a primary school teacher.
18,888 NSW education graduates were waiting for a full-time job at a high school.
6,966 New South Wales university students graduated as teachers in 2013.
But only 2,200 permanent jobs were available in NSW government schools.
The NSW Education Department gives priority to new graduates (presumably because they are cheaper).
More than 400 new NSW education graduates got a permanent job in 2013.
But only those education students on a scholarship were guaranteed a job.
New South Wales Education Minister Adrian Piccoli has introduced tougher requirements for students wanting to study teaching at university.
From 2014, NSW wanna-Be teachers will have to achieve band 5 in three Higher School Certificate subjects, including English.

Graduate glut puts trainee teachers on the scrap heap, Anna Patty, The Sydney Morning Herald, 20 October 2014,
More than 4,000 qualified teachers are unable to secure a permanent job in NSW - almost as many as the government's entire teaching workforce.
Universities pump out 7500 new teaching graduates a year.
Secondary schools face major shortages of maths and science teachers at upper secondary level - particularly in Western Sydney and in regional areas of New South Wales.
At least one third of the qualified teachers on the NSW Department of Education and Communities employment list who are unable to secure a permanent position gave up looking after four or five years, according to research conducted by the Board of Studies Teaching and Educational Standards NSW.
No school jobs available for thousands of trained teachers throughout NSW schools , Bruce McDougall, The Daily Telegraph, 8 July 2014
130 violent acts against New South Wales school staff were logged during term one and term two 2011.
There were almost 460 serious incidents in total in NSW schools.
Some of the most serious incidents involve intruders with a grudge, or angry parents.
Some students threaten their teachers, throw furniture, smash windows and assault their teachers by biting, kicking and hitting.
A number of NSW teachers are forced to seek an apprehended violence order for protection.
Mr Ferrari said using a methodology that showed the average indoor pollution levels over a six-hour period downplayed peaks when nitrogen dioxide, carbon monoxide, carbon dioxide and formaldehyde were concentrated in classrooms.
Tests at Blackheath Public School in the Blue Mountains were undertaken 18 months ago.
They showed gas levels in 30 per cent of classrooms exceeded international health guidelines.
