My DS2 started secondary school with no support and unfortunately the experience was not good.
Despite me providing the school with a mountain on reports - highlighting the important areas of concern, so at least if they didn't read it all, they might read that.
My son's primary yr6 and SENCO met with the secondary school before he started and outlined his areas of difficulty, I was at the meeting and the primary school did this very, very well.
The outcome? Secondary school devised an IEP which the teachers on the whole ignored.
Some of the things stated in the IEP were not difficult - please ensure DS2 has recorded his homework, if he is unable, please write it in his planner for him. Did they? no, not only did they not ensure it was written in, they had the cheek to continue to give him detentions for not doing said homework 
Please give him homework in manageable chunks. Did they? no to that as well. Just got the usual printed, we don't need to think if we had this out every year, extended homework, which he had to work on over a period of weeks.
They promised the earth and delivered nothing. On the league tables, they are the highest in the league, apart from the selective grammar schools.
Primary had applied for a statement before he left, it was refused, so secondary had to ask for it to be reconsidered. All SENCO did was re-hash some of the reports I'd given her into a letter. Fortunately the Ed Psych did an excellent job of convincing them to reconsider and DS2 was awarded 20 hours support.
We decided to change schools to one with a specialist resource unit. Best thing we ever did. it's not been plain sailing, but on the whole it has been much, much better. Don't be afraid to move schools if you are finding that your local one does not come up to scratch. My DH said he felt that there was a 'constructive dismissal' type thing going on at the first school. My DS2 would have lowered their fantastic achievements. Who knows.
Sorry this is not very positive, but please be prepared for a battle, and if you don't need one, all well and good.
