I had to go into my DS school before term to collect books. Just went in, someone asked could they help, sent me to where the books were. I have been before when they called me to say DC is sick. You arrive, enter the school, go to reception, they call your child. I am happy with this but I believe in UK you would have to ring a bell, and get let in. So more control over who gets into the school. I am curious about if my experience is the norm? Importantly, not primary school, she they're eye more controls I n entry and exit
