One in six teachers working outside their area of expertise documents reveal

More than 100,000 NSW high school students are being taught by someone without expertise in their subject due to increasing teacher shortages in areas such as maths, science and even English and history, confidential documents show.

Internal analysis done by the NSW Department of Education also showed that students whose teachers were qualified in a subject discipline â€" particularly in science and technology â€" achieved higher marks in the Higher School Certificate than those who taught by a non-specialist.

The workforce analysis was part of a confidential NSW Department of Education teacher supply strategy to address a looming teacher shortage, revealed by the Herald on Thursday, which warns of insufficient teacher supply in NSW by 2026.

Overall, 15 per cent of teachers are operating in an area they haven’t been specifically trained for. The shortage is worse at secondary level than primary, with 14 per cent of secondary teachers teaching out of field. That includes 22 per cent of years 7 to 10 maths teachers, 12 per cent of years 11 and 12 maths teachers, and almost 20 per cent of junior high school English and history teachers.

One document showed an attempt to boost maths numbers by luring people in other careers to retrain as teachers with the offer of scholarships floundered, attracting the “relatively low number” of 48 applications, of which only 17 were suitable. The government has pledged to attract 4600 extra teachers over four years.

Craig Petersen, the head of the Secondary Principals Council, said he was not surprised by the data. “[The shortage is] not new,” he said. “It’s more pervasive than it has been. It started in our rural and remote schools and spread eastward, to disadvantaged areas of Sydney.

“Now it’s pretty much everywhere. Particularly in maths, science and technology, but it’s now pretty much across all subjects.”

One confidential paper, dated June 2020, analysed timetable data to find the areas of greatest shortage and identified the areas in which teachers were most likely to take classes outside their areas of speciality.

The most heavily impacted areas were maths and science, with 22 per cent of years 7-10 maths teachers and 16 per cent of years 7-10 science teachers unqualified. Special education is also faced with a severe shortage of qualified teachers.

“The demand for maths 7-10 and 11-12 and science 7-10 exceeds the number of available teachers,” the report said. “We are reliant on out-of-field teachers to meet the current demand.”

The report also analysed the impact of out-of-field teaching on HSC results and found a qualified teacher, on average, led to higher scores.

The difference was not statistically significant in maths standard 2 or English. However, a qualified teacher was associated with higher average HSC scores in science (except biology) and technology courses.

The confidential documents â€" released to State Parliament under rules allowing MPs to compel information from government â€" said the department’s mathematics teachers were generally older than the average teacher, with most aged over 45.

“Expected teacher completions for in-demand subjects â€" mathematics and science â€" are at best low but stable,” it said. “There may be insufficient numbers to replace teachers of high demand subjects with an in-field teacher.”

One of the documents said keeping retiring teachers in the job would be crucial to maintaining supply in subjects with acute shortages.

One of the government’s strategies to boost supply is to attract people from other careers to retrain as a teacher.

However, a report on the Teach.MathsNOW program to target career changers resulted in a “relatively low” number of applications, which an analysis attributed to set salary structures with limited capacity to recognise qualifications outside of teaching.

Many applicants also did not want to work in the geographic areas in which they were most needed, and some were deemed unsuitable when it became clear they did not have an aptitude for teaching, and their motivation was “perceived lifestyle benefits”.

Angelo Gavrielatos, the president of the NSW Teachers Federation â€" which is about to enter wage negotiations with the department â€" said teachers had been warning of a looming shortage for years.

“We have been waiting 10 years for a 10-year workforce plan from this government and they have produced nothing so far that reflects the seriousness of the situation or the size of the solutions required,” he said. “This will be a test of the new Premier’s commitment to our children and our teachers.”

The NSW government has pledged $124.8 million over four years to a teacher supply strategy, which will include new incentives to work in rural and regional areas, and a plan to attract STEM teachers from overseas.
