I don't want to diss any teacher we all have it hard enough! And I have huge respect for secondary teachers, I would be terrified of teenagers.... 
I honestly haven't seen more than two pieces of work marked from the beginning of this term. I appreciate that there are exams and assessments etc.
I don't really know the ins and outs of secondary timetables etc.
I mark three, often four sets of 30 pieces of work a day, all with next steps, all which gets checked every few weeks, along with a very brightly coloured feedback document detailing whether my marking and feedback is outstanding, good, requires improvement or failing.
I do feel like my dd isn't getting any feedback, none that I can see in her books. I have seen one next step written by her history teacher, which she responded to.
I think it's just different, maybe I need to get over myself a bit, and she needs to get used to far less feedback.
