On Tuesday the EWC panel heard from a girl who was taught by Ms Ashton twice a week for around three months, referring to her as pupil H.
She described a Personal and Social Education lesson – a subject which includes drug and alcohol awareness - taught by Ms Ashton on 17 January 2024.
As she was sitting near the teacher's desk, pupil H said she noticed there was a alcohol smell coming from an Evian bottle, and said she shared "a knowing look" with another pupil sitting nearby.
Pupil H added Ms Ashton was smiling and happy at the start of the lesson and kept getting up from her desk, but that she became more irritated as the lesson went on.
The pupil also alleged Ms Ashton swore at the whole class as they became rowdy, and at one point put her middle finger close to one boy's face and swore at him, but did not remember exactly what was said.
Presenting the case, Lewis Harrison asked pupil H if there were differences between Ms Ashton's usual teaching and the incident.
Pupil H said Ms Ashton would normally just get on with the work and that the class had never had any lessons like the one on 17 January.
The panel also considered the evidence of another member of school staff who spoke with Ms Ashton on January 17.
The member of staff said she could not understand what Ms Ashton was saying, describing it as "like a jumble of words", and that Ms Ashton stumbled and staggered as she went to lean up against a wall.
