I have to admit I find it odd that a kindergarten teacher appears to be regularly leaving the room, or that one can be "behind" in writing at the very start of the year, or that a kindergarten teacher would say things like "his behaviour needs to improve". Or what?!? If he is academically ahead by up to two years, where else should he be or what should you do? Seriously, it could be developmental, or ADHD, but the way she is venting her personal frustration does not sound very professional to me. What is her plan if he does not "improve as required?"
