whether to accept or reject non ranked allocation

We similarly got allocated the school we didn’t pick and wouldn’t have been right for our daughter.
As hard as it was we had to accept the place, as recommended, at least had a place somewhere. We went through the appeal for the school we wanted for her, and made sure we on the waiting lists.

The day before we due to go appeal panel we finally got allocated the school we wanted.

I think someone has mentioned but in case not as I've only skimmed and was jn this position 2 yes ago. Accept, appeal and add yourself to other waif lists. We are only able to have 3 preferences, our 4th would have been catchment and we didn't get into any of those nor 2 closer schools than the offered place. I got him on the wait lists and he got offered what would have been 5th then 4th before September.

Do not reject

Do not reject the offer unless you would genuinely rather homeschool or pay for private (and have the time/money to do so). Accepting or rejecting the offer does not make any difference whatsoever for either appeals or waiting lists.

There is no upper limit to the number of waiting lists you can join so if there are any schools that are more preferable than your allocated school and were not on your original preference list you can join those too.

There are going to be a lot of changes between now and September. There will be a good chance that you get an improved offer at some point.

As others have all said, rejecting the offered school doesn't force the local authority to offer an alternative, it just potentially leaves you with no school at all. The schools you list on the form are preferences not choices (might sound like semantics but we don't have a choice based admissions system)
Your appeal reasons won't carry any weight at all unless there are very specific curriculum offers at the preferred school (and not based on what the preferred school offers at GCSE because that can change over time anyway) you need to prove that your child being offered a place outweighs the detriment to the school and always remember you are appealing for the school not against the school you've been offered.

As others have said, do not reject the offer.

There are always some people who reject the offer because they think it gives them a better chance of getting a preferred school. The ones who say “Well, they won’t leave my kid without a school, will they?” This is foolish. No, the LA will leave the kid without a school place because they have already offered a place. It is the parent who is actually leaving the kid without a school place. The kid will go to the back of the queue.

Do not reject the offer.

There is no upside to rejecting the offer. It will not improve the odds of your daughter getting a more preferred place and could leave you in an even worse position.

School place allocation isn't a negotiation process; there's no option to pressure the LA to make you a better offer by refusing their initial one.

Make sure your DD is on the waiting list for the preferred schools you listed and also do the same for other area schools that you didn't list but might prefer over the one you were offered. You can certainly file an appeal, but to have a chance of success you will need to develop a far more specific argument than what you presented here. "It's a better school" isn't an appeal-winning argument; you need to find specific things about the school you're appealing for that your daughter specifically needs.

You have had some harsh but realistic responses OP. As others have said, accept the offer, it is an insurance that your child will have a school place in September, it is not mandatory that she takes the place in September if the waiting lists gain you another offer. And if all you know about the offered school is hearsay then do your own investigation, the school may have qualities you don’t know about.

In the meanwhile it is worth checking that the LA has all your address details recorded accurately, that you were considered under the correct criteria ( eg linked school,sibling link, LAC, baptism and attendance criteria if a faith school ) and that if you were refused on distance that the distance measured is accurate. None of the above are likely to have happened, but they could have so you might as well make sure.

As well as appealing, check that you are on the waiting list for all your original preferences AND investigate other schools that you might prefer to the allocated one that might have space / you might be high on the waiting list for.

Unfortunately you have been naive. The local authority are obliged to offer you a place, but it doesn't have to be at one of your listed preferences. If you reject their offered place then you will need to home educate or go private. If neither are an option, then your best bet is to accept the offered place but stay on the waiting list for other schools.

You are unlikely to win an appeal on the grounds you have stated. Imagine if everyone who was unhappy because they didn't get the place they wanted was able to do that?

If you reject it you risk having no place at all, if appeal and wl do not come through. It would not strengthen the appeal case to do so.

Do not reject the offer. I know 2 people that rejected a non ranked school offer (now year 8), 1 ended up with no school in September so had to be home schooled - still is a year later. 1 got a school but not until 1 week before School started and it was still not one of their preferences. Accept the place and stay on the wait lists but accept you might not get a different option.

Nothing you have so far mentioned sounds like a likely winning argument at appeal.

You need to find some strong arguments about why your preferred school would meet your child’s needs and why she would be disadvantaged if not given a place. Reading the very many appeal threads here may give you some ideas.

@sunnmoon if the LA demonstrates that the school is 'full', then the admissions appeal panel will need to decide if they can take any further pupils, and if they can, which pupils it can take. You could find yourself in a situation where your appeal case is being compared against 5 or 6 (or even more!) other cases, and only the strongest will win. So it isn't enough to say 'she'll be really sad' or 'the curriculum is better.' You need to be able to convince a panel that your DD needs that place so badly that it's more important that she goes to the school than any difficulty the school has with accommodating her, and that she is more important than any other child that has appealed.

Are any of the schools on your list your catchment school?

Yes as others say, you are best to accept the offered school. Doing so will not affect any appeal or WL offer. But if you reject it, your DC may be without a school place in Sept so you will need to either HE or go private.

The LA has offered you a place and it is not obliged to do anything else.

Re the appeal – the arguments that your DC is not happy and will be at a disadvantage (why?) will not carry weight. The argument about the curriculum is stronger but needs to be specific – for example, she is learning x language/has a grandparent that speaks it and it is only offered at the appealed-for school.

You say you were not allocated any of your preferences (note – not choices as there is no guarantee) – did you list your local or catchment school? Were all the schools you listed somewhat optimistic (as in, you wouldn't usually be offered) or were they more realistic – if the latter you may be high up on the WL and get a place that way.
