I used to work in education.
I loved teaching.
I still love teaching.
It's the paperwork outside the classroom that takes up the time.
For example:
Say your year 11's do a mock. In order to give them detailed feedback on what topics to revise, you need to type into an excel spreadsheet their marks for each student for each question, this takes about 2 hours.
Some schools have a policy on marking. So they will say that you need to do something called triple marking.
So that means that you mark the piece of work, you then need to (hand write) feedback for them of something they did well and something they could improve.
You then need to write how to improve and give them a feedback task to show in writing that they have improved.
For example:
That was a great sentence David. Good use of an adjective. To improve, please use capital letters at the start of each sentence.
A capital letter looks like this
The man bit the dog.
Now circle which sentence has a capital letter at the start of it:
all ravens are black
All ravens are black
I used to waste hours of my weekend writing this stuff out. The school had a policy it had to be handwritten. It took about 5 hours per class.
They did drop the requirement for it be handwritten but it still was supposed to be individual feedback so you got into trouble if too much of it was the same.
I didn't mind too much doing stuff like the data entry on the mock because it did genuinely help the kids know what they needed to revise. The triple marking shit was just a waste of time though and you do hit the point where you resent paperwork for the sake of paperwork.
