Thought I would share as we are all quick to point out the negatives with schools and teachers, also it's not something I'd mention in real life to friends.
Unfortunately I was at work so she left a message on our house answer phone.
She introduced herself as DDs English teacher and went on to say how well she is doing in her lessons and how impressed she is with the quality and detail of her work, and could I please pass on her congratulations. 
I just think that's lovely that she took the time out of her busy day to get in touch, particularly as most school phone calls involve complaints about my other DD, although she has been improving this year.
