Tea, he doesn't have a 'special worker' at all. One of the members of staff at the nursery have to be the 'special educational needs coordinator' - one of them, this job is pretty much always double hatted - usually with the nursery manager more often than not, but sometimes with one of the ordinary key workers. Ds doesn't have a special worker, they have just asked the senco to have a watch of him and give an opinion.
If it is felt that he does have some additional requirements (within the setting), the senco, in coordination with his ordinary key worker, will come up with an iep (an individual education plan) - for Ds, this might have a speech target and a behaviour target such as sitting still for five minutes during story time. It will also state how they will help him meet those targets. He will be on the 'school action' list, which means he needs a little more support than his peers, but no external professionals involved.
If you do get the go to refer for developmental paed assessment, and they refer on for speech and Lang therapy, then the SLT may come into the nursery once in a blue moon (usually no more than once a term) and will have input into his iep target for speech. He might also get some external speech therapy at a child development centre.
At that point he will be put onto the 'school action plus' list, which means he needs some support from external professionals and the school/ nursery to keep up with his peers.
Children go onto and leave these lists all the time as they catch up, or their development slows in comparison with their peer group.
if he consistently fails to meet targets on his Ieps, (over a year or two, possibly longer), or nursery are having huge problems containing his behaviour (violence towards peers or staff/ doing a runner in an unsafe environment etc) then they could ask the LA for a statutory assessment, to see if his needs are severe enough to be given additional funding for a statement of sepecial educational need and a 1-1 key worker for a set number of hours. This
Rocess takes at least six months and can be longer. This is not the senco. The senco is there (doing her other job as well, primarily) for all of the kids. The 1-1 key worker would be solely employed for Ds. This is not where he is at at the moment.
If nursery believe that immediately his behaviour and communication issues mean they cannot cope, they can ask the Area Inclusion Officer (like the Senco but from the LEA) to come in and assess, and very occasionally they can come up with some additional early years funding for a few hours a week (or ft for v complex children) to provide some additional support to the nursery.
At this point, Ds has (or may have, in the opinion of a senco, who largely are completely untrained in sn) some issues that may need some support.
please don't let your imagination run away with you and dx him with severe sn because of a conversation with an untrained nursery worker at 2.
Please.
This is a hint to get the GP involved for developmental paed referral, and see where you. I suspect you will get a SLT referral, and potentially a place on an early bird course for parenting skills appropriate to preschoolers with potential sn, at the very most, at this point. If it becomes more apparent as time goes on that he does have some sn (which hasn't been considered at all. Y anyone yet), then it will be time to negotiate statementing etc.
Have a read up, but just see the GP and try not to panic. You have a child that may need some additional support of some sort. Not a child with severe sn. It's really easy to panic when someone suggests sn, but you have a looooooong way to go before that becomes a reality.
