as I said above, it is entirely possible to give a sanction for every little thing without it being an after school detention.
As I said my ds and dd go to two schools. Both have large numbers of kids on buses. Both have worked out punishment systems which do not use after school detentions as first point of call.
ds school has a black mark system. Every single black mark = email home with reason why. 12 black marks = meeting with deputy head and DH phone home and talk to parents.
Any serious incident (misbehavour type, not serious as in eg violence) = phone call home to discuss.
Note - the school manages to do as much as possible over the phone, they don't insist that parents come up to school. Why? because most kids are bused and therefore don't live that close.
In the whole of year 7, 8 and 9 they only got as far as after school detentions with about 3-4 kids. Pretty much every single kid did not get as far as 12 black marks.
They have zero tolerance over forgotten kit, phone use, homework not handed in, school uniform etc.
They manage it. Why can't other schools?
This whole comment was really in response to the issue of kids on buses and after school detentions. Some schools in our county have 80-90 % of kids on buses - rural areas. If a school has a different demographic, fair enough, but part of being a good head is knowing your particular school, and your particular set of parents.
Common sense on behalf on senior management is a very useful tool in parent school relationships.
