Not me, but I can tell you a bit about my daughter's experience. In her second year at university she volunteered as a tutor as part of a scheme set up to support year 10 and 11 students in local schools. She really enjoyed it, kept it going remotely during the Covid lockdown, and then decided that she wanted to train to teach.
She graduated last year and thought about staying on at her university to do a PGCE there. However (partly in order to save getting into more debt) she decided to come and live back at home and train here.
The training is organised by a consortium of local schools. They allocated her to a 'home' school, where she spent her first term. She moved to a different school for her second term and she is now back at the first one.
One day a week is off the job (1.5 days a week in the first half term). Some of that time is spent on general issues such as safeguarding or assessment, and some is subject specific. She had to write a dissertation and, assuming all goes well, she will get a PGCE as well as QTS.
It has been hard work - she has been working very long hours preparing for her classes - especially as, since January, she has also been teaching a second subject that she has never studied so she has had to get to grips with the A level and GCSE specs and the necessary subject content. But she has found all the staff very supportive and has loved getting to know and developing positive relationships with her students.
Overall, she is really happy with the experience. She has also been getting great feedback from her mentors and other observers, which has given her confidence that she is doing the right thing and that she has made the right career choice.
I suspect that her experience is not entirely typical. She has mainly been teaching A level students, plus a couple of GCSE classes (neither subject is taught before KS4). That means that the classes are typically smaller than they would be further down the school and the students (especially at A level) are also probably better behaved.
Obviously she doesn't have anything to compare it with, but she is very pleased that she went down the school-based route. She has felt valued and supported, both by the central consortium ITT leads and by the schools she has been in.
The 'home' school in particular did a good job in making her feel welcome and a real (if temporary) part of the school. The head took a personal interest in the trainees based there. He has offered some of them jobs for next year. He didn't offer my daughter one because there was no space for her, but he told her he would have liked to do so and that he would look out for opportunities for her. True to his word, he phoned her a couple of weeks later to say that he had recommended her to a colleague in a school a few miles away.
She will be starting at that school in September. She will be a form tutor and she is really looking forward to getting involved in the pastoral side as well as the subject teaching.
I guess no one knows whether teaching will suit them (or they will suit teaching) until they try, but for my daughter at least, it seems to be a good fit. Good luck with whatever you decide.
