badkitty I suspect there is a simple explanation. It sounds, from the few lines you have shared, that the LA intend that your son will go to a special school. They can't explicitly state that, because you have the choice to send your DS to MS, but they often indicate it in the text.
For example:
'environment adapted to his needs' - special school, generally. Although MS schools can have hoists/grab rails/ramps installed.
'developed by professionals and implemented by staff' - again, something that is done quite effectively at special schools.
Generally speaking, special school statements tend to be quite vague and wooly because the stuff that would be specified in a MS statement is the 'bread and butter' of special school life.
That is NOT to say that you can't insist that it is specified and quantified. Of course you can. But, for example, in a special school 1:1 is very rarely necessary, because the staff:pupil ratio is so high and the facilities are so well equipped for the children's needs.
Also, in many special schools, the physio/OT tends to do constant monitoring and ad-hoc intervention, rather than set sessions, so that the children get what they need when they need it.
