@Juliet37 pre-covid we had a face to face meeting with his form tutor about 2-3 weeks in. Mainly to convey whether they are organised, settled into the routine of getting all their required equipment out in form to be checked, that their homework is being completed and handed in etc. His form time was 30 minutes every day where the teacher checked their planners to see if there were comments or negative behaviour marks etc. It was also a hello from them and meeting us the parents.
This is an outstanding state school, there is a box in the planner you tick to say you want a telephone call home too. That means the form teacher will call you within 48 hours. They also have an email for the year group and you will get a response, again usually a telephone call within 48 hours. Depending on the contents of the email it can be a subject teacher or pastoral.
It is very different to primary where you see the one and only teacher they have for all lessons on the door. If you want to speak to someone, look at your child's planner or welcome email from the school which should detail how to contact them. And then contact them.
I don't know if this will help you but when mine started secondary, they went through their timetable and gave us a brief description of what they did that day, ie maths we did algebra, science we did osmosis, history we did Tudor England etc. We felt that was a great way to expand their knowledge, talk about those topics etc. Our friend is a head of subject in a different school and he said those children that read around a subject (not read specifically but YouTube basically) are the ones who are more successful academically.
