Herbaceous:
First of all relax. It will all work out. I was exactly like you and wanted to know in fine detail (primarily because we had a fabulous nursery with great communication so it seemed a real comedown to have cursory information and vague understanding about what would happen). Also I didn't get first choice school and I know what a shock that can be.
YOUR QUESTIONS:
such as term dates, inset days: Go to school websites or go to letter section - read last newsletter or look for a specific term dates letter (the school should have informed the parents at the end of the previous year - but with a change of head they may have left it to the new head). [Remember you don't know whether this is a Head leaving after years of happy service or being forced to go - this could be very political and therefore quite chaotic, but will settle once the new school year is off and running].
There also is a school diary usually on the school web page - open this up and see what they have. Useful things to note down in your own diary: dress up/ MUFTI (when you come in ordinary clothes) days (do not be the parent who forgot), parent/ teacher meeting dates (you'll probably have to sign up for a slot but good to keep those evenings clear), assemblies for Class R, inset days/ school closures (half-term, etc...).... (if none of this is truly available - which is odd - then e-mail contact address for school and explain that you can't locate the information, could they let you know what day school starts & what time - explain your childs name & date of birth - if you know who their teacher is say this too - because if if is more than one form and if children are coming on different days (which they might be organising right now) - it isn't a simple question).
rough timetable - if you still have it - look in the prospectus (should be available on-line as well) - almost every school sets this kind of thing out for prospective parents. (if you want to know dates for next year remember that teachers are now on their 'holidays' and doing background prepartory work most likely this type of thing will start to go up on the website over the next few weeks. Also bear in mind that first few weeks of Class R is about settling in, assessing children, etc... - and that the normal 'routine' won't quite be in play yet. Most schools will have a meeting with parents of reception classes to discuss school routines/ phonics/ EYFS etc... early in the school year. This is where the 'now that we've settled in, this is what we'll be doing talk happens'
curriculum - Unless they're an academy they'll be following the EYFS & national curriculum and even if they are an academy they'll still be more or less following it.
My advice is visit: <a class="break-all" href="http://webarchive.nationalarchives.gov.uk/20130401151715/www.education.gov.uk/publications/standard/publicationDetail/Page1/DFE-00023-2012" rel="nofollow" target="_blank">webarchive.nationalarchives.gov.uk/20130401151715/www.education.gov.uk/publications/standard/publicationDetail/Page1/DFE-00023-2012 - remember that Class R is basically an extension of nursery school (if your DS went) and EYFS (early years foundation stage) targets are for ages 3 to 5. Your child will not be assessed against the national curriculum until they're in Year 1. Year 1 & Year 2 are Key stage 1 and Years 3 - 6 are Key stage 2.
Mumsnet has information about assessing progress in Reception here: www.mumsnet.com/learning/assessment/assessing-progress-in-reception and general information about assessment/ progress through school here: www.mumsnet.com/learning/assessment/introduction
uniform - check prospectus (paper copy or look for this on-line) & look at pictures of pupils in prospectus & on web - to get an impression of what kids actually wear. My advice is buy core uniform. 4 polo shirts, 2 pairs trousers, a pair of shorts (September can be warm) & plain jumper/ sweat shirt & then buy in what's popular once you've seen the school more and your DS also forms opinions. Do buy ordinary raincoat (light) & winter coat as soon as you can. At our school the school fleece (which is very comfortable) is hugely popular. [label everything (even shoes) - buy in name labels & use indellible markers as well]
lunch arrangements - again check prospectus but if you are having an individual meeting with the teacher before school starts ask then. Our school gave this info out on day 1 and all children were allowed a school meal if they hadn't brought a pack lunch and parents could pay in arrears. You can also ask on the morning and go to the office and pay then (gives you something to do after dropping off PFB and lets you see a bit more of the school when open for business)
whether/when he'll do PE/music - come on - this is a school & he & his class mates are 4 - of course he will. They'll also have 2 breaks a day and most schools allow children to roam a bit and have a quiet corner for children to nap if tired. RELAX!
what he needs to be able to do - put on shoes/ get dressed, go to loo on his own, open lunch box/ containers (if you're sending lunches in) and play well with others (helps to get in teachers good books).
what he needs to bring - Day 1: himself in school uniform & PE Kit. School will provide pens, pencils, papers and all other materials. If they need something (for an art project or something) they usually put a sign up in the window and/or send notes home.
when the school day starts: Again check prospectus - that's got to be there.
Their website is two years out of date, and thus useless. - OK this is your 5th choice school and I suspect with a Head leaving and a new one arriving things are slightly 'in flux' at the moment. But be logical. If you've read the prospectus, looked on the web and rung - what else could you do to find this stuff out. Put on your 'business head' - would you expect a client to work out what you're selling and when without any advertising. RELAX. They haven't told you/ you didn't know/ you didn't understand: When you are asked/ informed to do something - then do it.
I was a lot like you Herbaceous but the fact is that teachers and a new Head means that there's most likely a lot of politics, change & hard work going on (especially in planning changes) behind the scenes and that a parent wading in and demanding to know x, y, z in fine detail is never going to go down well.
Do you urgently need to know something? School starting time & date - yes - but I'd be really suprised if that wasn't in prospectus, on the web-site or even on aswering machine. E-mail the school contact address for information on start date & time (but be sure to add child's name, date of birth & teacher's name, if you know it).
My advice to you is that right now you need to enjoy the tail end of his last summer as your little boy. Work on skills like dressing on his own, being able to take off and put on his shoes, recognise his name, write his name. You don't have to be able to read yet - but should know about books and be able to sit quietly and be read to.
Accept that this school is going through a major management change and that right now the priority for the Head may be getting rid of poor performing staff and putting into place higher expectations on recording pupil progress, staff performance, etc... It's easy to forget that they're a business with external pressures and priorities we just don't see as a parent. Right now the school may be more focused on what their issues are than the new intake and what they might need to know. However, they'll be more than aware that new parents will need information and I suspect will be sending that kind of thing out shortly.
Finally check through your old letters and the information you were given at this big new parents meeting with the school you described. Quiet often this kind of thing was there in handouts, new student packs you were given - but it was just that you were so overloaded with information on the day you didn't absorb it. If you've lost it - e-mail the school and ask them to send you another and that it can be digital). Worse case scenario - set a deadline - say Tuesday August 27th - and if you haven't resolved when school is starting & what time - contact the school and ask.
Hang in there!
