My DD is in yr3. Her teacher left at the end of the first term. Her new teacher works Mon-Thurs, and we were told by letter that her class would be taught by the dep head of year on Fridays. Yesterday she told me that they now have a THIRD teacher who will teach them on Monday's. Aside from my concerns about the quality of education she is currently receiving under this set-up, am I being unreasonable to expect the school to inform me as a parent and tell me why? Thank you.
