@NotAPsycho ,
Why do you think you can best decide what is important in education?
The thing is that if teachers make these planners, that is time they cannot spend on other work, such as preparing exciting new lessons.
I was teaching in private for 10 years in a scarcity subject, as a second career, and it was entitled parents like you that, at least in part, led me to leave at the end of last year (plus ludicrous marking requirements and a culture of presenteeism in the staff work area).
Ultimately, I went into teaching for the pupils, as most do, but as senior professionals (as teachers are termed by schools), we don’t like to be micromanaged, and certainly not by parents!
Teachers need to both be paid appropriately to their skills, and respected as professionals. If that doesn’t happen, the bad teachers stay and the good teachers leave.
