on my phone, but FAR OUT! i'd be very unhappy with that school.

a list of complaints will help you start a very stern appt with the principle and teacher? I would be discussing a few things with them- this is prep- not year 3.
we have done this a few times and you might find a more parents think the same. have a chat to the other parents if you can

If a letter got sent home to me about my child and speech issues I wouldn't send the letter back, id get down there and talk to the teachers. I think both parties there haven't been great, sorry.
we work closely with our children's teachers. try get to know them and their teaching style and find how to back each other.
some schools arent run well but Im not going to let my kids suffer because of it iykwim.
