Thank you for all your replies most of which have been very helpful and actually gave me a direct answer to my question.The reason I asked this question was to ascertain that this was normal practice particularly where mental health problems were present. Well it seems it is, so I am not going to discuss with the school something that is standard practice whether I agree with it or not.
I really don't need worthless comments telling me to " talk to the school or move her on" and even further comments bordering on nasty and inferring my daughter is not my priority and the school might throw her out anyway and I then would not have to pay Autumn fees. I mean why somebody should be talking about money and Autumn fees to my straight forward question is really beyond me !
I only ever talk with the school if they appear to be in the wrong, and in this particular instance they appear to be within their rights irrespective of my daughters current situation. I accept that and will "move on " and continue with the school since at this later stage of my daughters education we have very little choice anyway.
Mentioning a dossier was obviously a mistake on my part as it was bound to attract certain people that decided to start assuming things in their minds about what intentions I had and asking me questions about that rather than answering the question I had implicitly asked. However for clarification it is nothing too deep , it was in fact just a bullet point reminder to ones self about certain instances in relation to my daughters mental health that I felt could have been handled better. I have learnt from past experiences(not education related) that having accurate records can be very important should they ever be needed at a time in the future for any unexpected reason. Its basically just prudent housekeeping , after all we are often told by others when we are not totally happy about the way things are going or how we are being treated by different organisations to " record everything, take notes and get it in writing....
just in case ".
Right now I have no intention of making an official complaint to the school or anything remotely similar as the school has already acknowledged in passing that some issues could have been handled better and I accept that oversights or bad communication within schools can sometimes happen. Let me say that on whole the school have been very good, they have tried to support my daughter as best they can and I of course greatly appreciate that, however where I consider a decision is being made that will negatively impact on her mental health I will certainly stand up and ask to be heard ,request they reconsider or at the very least explain their stance. I do not believe any other caring parent in the same situation would do anything differently. I also believe a good school should be perfectly happy to listen to your point of view, as no institution gets things right 100 % of the time and sometimes they are grateful for your input as a parent.
It is almost impossible to explain just how intense and stressful having a child with mental health problems is to those that have never experienced it. From her birth until around 14years I had indeed not experienced it, every school year my daughter had at least 95% attendance at both junior and senior schools, and on the whole was a very happy child enjoying life in general whether at school or otherwise. Then puberty hit and everything changed and now I know exactly what it feels like. Unless you have been through similar experience with an older sibling then trust me there is no dress rehearsal on the planet that can prepare you for this. You have to quickly learn on the job and if that means questioning a few decisions when your gut feeling is telling you they don't feel right then that is what you do. However sometimes you find yourself on the fence given a particular situation and can see both sides point of view. Its at times such as this that these forums can help people to make a balanced decision based on the majority of peoples answers, real life experience and opinions . Your answers (well most of them) as stated have helped me reach that balanced decision , so thank you.
