Headteacher considering withdrawing my ECT job offer – did I mess up badly?

Hi everyone, I’m a trainee teacher in England (PGCE/QTS) and I’m really stressed about something that happened today and wanted some honest advice.

Earlier in the year I was offered an ECT job at my placement school starting in September. Today the headteacher called me into a meeting and said she is considering withdrawing the offer due to concerns about professionalism.

The things she mentioned were:

- I missed around 5 United Learning training sessions.

- I left school at around 3:39 one day when staff are expected to stay until 4:30.

- I applied to what I thought was a tutoring agency, but it turned out to be a teaching agency and they contacted the school for a reference.

- My professional mentor saw me using ChatGPT while working on a lesson plan.

When she told me this I got really upset and honestly started crying and asked for another chance because I really want the job. She said she’ll think about it overnight and let me know tomorrow.

I feel embarrassed and anxious now and I’m not sure how serious this actually is. None of these things felt huge to me individually, but I understand that together they might have raised concerns.

My questions are:

- Do schools actually withdraw ECT offers over things like this?

- Is there anything I can realistically do at this point to fix the situation?

- If the offer is withdrawn, will it affect my chances of getting another teaching job?

I’d really appreciate advice from teachers or trainees who’ve experienced something similar.
