I am not making any assumptions, Lemon. However I will point out additional needs cannot be ruled out.
If, as so many posters seem keen to, the OP's other threads are taken into consideration, the OP's daughter's difficulties with concentration in a classroom environment and conforming to behavioural expectations, are more clearly apparent. These kind of issues, coupled with the ineffectiveness of the school's sanctions, have been going on for quite a sustained period of time. This alone, would warrant further investigation, including trialling other behaviour management techniques, in order to meet this child's needs more effectively, IMO.
Additional needs are not made official until an assessment is made. Additional needs also may not even manifest if they are met, as a matter of course. It is can only be when needs are not fully met, that additional ones become apparent. In this way, a rigid, inflexible, approach creates a manifestation of additional needs. The parent, may genuinely, have not acknowledged any additional needs if she, naturally and effectively, meets her child's needs without thinking. So it is quite feasible for any additional needs to only have manifested once a child starts school or on a change in the school environment.
