A Queensland primary school teacher was so drunk she passed out in front of her grade-two students, in one of a string of incidents that exposed children to "considerable risk", the Queensland Civil and Administrative Tribunal (QCAT) has found.

The woman, who cannot be identified, has been banned from teaching for two years after she was found drunk at school on multiple occasions over a two-year period.

The tribunal recently handed down its findings against the former teacher.

The QCAT heard that on a morning in August 2016, the woman had taken several doses of Valium and drank vodka disguised in a water bottle while teaching science to grade-two students.

An ambulance was called after she fell unconscious at her desk.

On one day in September 2016, she went to her car to drink vodka and take Valium at least twice.

The school principal found her sitting at the front of her class with her eyes closed.

She was taken to the principal's office, but the teacher then left in her car.

The principal notified police, who pulled the teacher over. She returned a blood-alcohol reading of 0.144 and was fined and disqualified from driving for five months.

While working as a relief teacher at a primary school in August 2018, the woman again consumed alcohol and Valium, before collapsing near the school library.

An ambulance was called and she was taken to hospital, where her blood-alcohol level was recorded at 0.34, which the hospital toxicology report indicated was in the level of "stupor" stage.

A reading of 0.35 is considered "coma" stage.

In other incidents, the teacher fell asleep on a computer desk in a grade-two science classroom, was unaware of an incident involving a child being punched, and collapsed after consuming hand sanitiser disguised in a water bottle.

'Inappropriate and frightening behaviour'

The QCAT found the incidents "most concerning" and her "performance as a teacher has been seriously compromised due to the consumption of Valium combined with vodka on more than one occasion".

The tribunal took into account her deep remorse for her actions and that significant personal stressors affected her state of mind, including the breakdown of her marriage, depression and anxiety.

However, it found the teacher demonstrated a pattern of behaviour that "exposed vulnerable children in her care to considerable risk; it exposed children to inappropriate and frightening behaviour".

The tribunal ordered the teacher be prohibited from applying for registration or permission to teach for two years from October 1.

She was also ordered to undertake psychiatric treatment for alcohol dependence and undergo monthly testing to prove a total abstinence from alcohol for at least six months.

If she returns to teaching, she must demonstrate an abstinence from alcohol for 12 months and continue treatment with her psychiatrist.

Queensland Tourism Minister Kate Jones, who previously held the education portfolio, said she was outraged by the teacher's behaviour.

"I absolutely believe that this teacher should've been banned from the classroom," she said.

"I am a mother of young children myself that are in the early years of schooling.

"We have a trust that the teacher that is looking after our child will be there and be professional.

"What I can assure all parents is that this teacher will not automatically go into a classroom. She will have to go through a process with the [Queensland] College of Teachers in order to be deemed to be a fit and proper person to be back in a classroom."
