Teacher on gate duty responsibility for non collected children?

[TooHasty]

DD1 school is in a rural area and most of the children (I'd say 70%) either arrive by school bus or car.DD has been having some trouble with a tooth and I managed to book her a dental appointment after school.I arranged to pick her up straight after school and drive her to the dentist.Unfortunately during the day my car had a major breakdown and the AA towed it to a garage who have ordered the parts.I arranged with my DF to pick DD up instead.He is very lame not in good health anyway and has a bad cold but he was insistent that DDs tooth needed sorting out.
Anyway he was delayed by 10 minutes and texted DD to this effect.Dd was quite happily sitting on a little low wall waiting.The last bus left and the teacher on duty approached DD and told her to go and sit in reception.DD told the teacher that her granddad was on the way but he was insistent that she could not wait alone outside school.This is a bit of a problem because my dad can't walk too well and it is quite a trek from the car/bus park to reception.
I suppose it is good that they are looking out for students, but do they really need to round up non-collected Yr9s 15 minutes after the end of school, who know someone is on teh way.A bit OTT?

They don't at DS school. It's rural too. There are always kids waiting outside after school and after school clubs.
They are not allowed phones on the school site till 3.30 so have to wait outside if they may need to use them, crap rule!

Not rural. But pupils aren't allowed to hang around at the gates (crowd control? Might not be an issue rurally, but is on a street pavement).

There are various places they can wait inside the school if they want to, and they can have their phones on after the last bell. Could that be the solution for you? The person picking up texts their new ETA and the pupil goes out at the new agreed time?

Was going to say when granddad gets there can he not just text to say I am here now.

It sounds a bit OTT for secondary school. It's all very well monitoring the departure of coaches and pupils who leave exactly at the end of school but do they have someone stand there for an hour or more to keep an eye on students (and let's not forget these are all aged 11-16) who are in end of day detention, have to collect their sports kit, see a teacher, get something signed from the office, go to football practice, attend a revision class, etc. At Ds's school, there seems to be a permanent trickle of people in and out all afternoon. If they just want to make sure that the main flow of people leave the premises without causing a jam or disturbing neighbours, why can your DD not just sit on the wall? If there is some kind of security issue why does that apply only to those who leave on time and not all those who leave later in the day?

As mentioned before, once a child leaves my DD's school it is their/or their guardian's responsibility to get them home. However, we are not in a rural location and I do appreciate all schools are different. Perhaps, it's something the school like to do as a safety precaution, so they know children aren't hanging around outside without an adult in sight.

I suppose the only thing you can do is ask your DD to show the teacher the text in the future, but also ensure whoever is picking her up has her mobile to say they are outside.

Seems a bit silly. There's 1,200 kids in the average secondary school, all getting home in different ways and no-one is keeping track that they're all getting home safely. One kid sitting waiting for grandad, hardly anything to worry about!

We live opposite a school and they do that here to stop the kids sitting on our walls, hanging around in our drives and stomping on the flower beds in the verge.

It's not a residential area so I don't think it's that mythicalkings She was sitting on the edge of a school wall that has railings on top.To be fair this event was a few weeks back and on a dark day it is coming in dark by the time they finish at 4pm

Could your father not have just texted her when he arrived and she could have then walked round to meet him? We had a thing recently where all the year 11's were coerced into taking part in a concert for the local elderly. We had arranged to collect my son when the concert finished at 9pm. However, unbeknown to us, the concert finished 15 minutes early. My son didn't have a phone on him because he had nowhere to store it and when my dh arrived to pick him up, the place was deserted. My son is a bit of a numpty so we had a panicked few minutes whilst my dh who is also a numpty tried to find him! :). However, at this school, there is no teacher herding uncollected children but I would have expected some adult still to be present because the concert had finished early and it waS late.
