Recently I read about an experiment with adjusting the time high school starts
Looks like the results needed more schools to trial this idea before drawing too many conclusions, see https://pmc.ncbi.nlm.nih.gov/articles/PMC6626292/However, as a parent and former teenager, I know the struggle to get to school one time.
Currently it frustrates me that my son needs assistance when I'm at my mental peak for the day, but I'm probably just looking at the internet anyway.
This week I was observing to him that his older brother got himself to school, then his sister started asking for lifts when there was an early start.
Now he, as the youngest, is now asking for a lift every day and is late more often than not.
I can't think of many occasions when I got a lift to high school and I've seen stories that (in the US admittedly) a kid making their own way to school is reason to question their welfare.
So I'm grateful that he's only got one more year to go before finishing high school, although I might be working in schools myself by that time.
