In general targets need to be smart. Very many IEP targets are not. Your new paperwork is better that your old one. Your first target is not really clear. If smart it should say how many words from phase 3 and if not all, which words you are refering to. Also it is not clear what 'concentrating on the middle sounds means' this needs clarifying. I think the sucess criteria depend on the targets but for example the 'read and spell' words from phase three target should give some indication of what is deemed to be sucessful. e.g x will be able to read and spell x number of words from phase 3 with x% acuracy. It should also include when this will be achieved by and give some detail of how this will be assessed and by who. I.e a TA saying 'it's about 50% of the time' is not as good as weekly test's/checks that are recorded and then used to monitor how many x is getting right etc. As an aside if you don't get much response on here, the SEN children forum on mumsnet has lots of very knowledgable parents, who probably who the sen code of practice in more depth than many teachers/senco's do. I think you'd get so very good ideas if you posted your question on there.
