So far I've got (from reading threads on here!) a few ideas what I need to know from the school(s) that we'll be applying to this winter. We are going for a look round our closest local JMI in a couple of weeks and I would like to have a few sensible questions (or things to look out for in their leaflet, if there is one)
What was your actual catchment for the intake of 45 last year and do you have any indication of e.g. a glut of siblings etc for this year?
Do you do complicated settling in sessions for a few weeks for the youngest in Reception entry?
What is your lunchbox policy? Drinks in water bottles policy?
Asking to go to the toilet policy? Assistance with the bottoms of inexpert wipers? 
What generic uniform is available (and what items are ruinously expensive from a single source)?
What do they do at playtime? How supervised?
What is picking-up-at-gate policy re childminders, relatives, etc.
What sicknesses do you send them home for, at what notice, how long excluded?
What are actual homework requirements by year? (time expected, typical task)
What do you do about both the most and the least capable in the class for things like literacy and numeracy - extra help/support, extra challenges, etc?
How much notice do we get of inset days? Nativity costume requirements? Extra money requirements for an outing?
How do you mainly communicate with parents? (do I need to look in a book bag every day for notes?!)
Are PTA/contact meetings held only during the day? what about working parents
I am reading the prospectus which mentions a lot of these things but not quite in detail. Like "Particularly able children are catered for within the class setting." - what does that actually consist of? My PFB DS is a real bookworm, will he be able to race through any books he likes or will he be held on the same ORT band risking him getting bored/frustrated? (which is what happened to me when I was 5 too!)
There must be others... Any suggestions? And I really don't want to be at all negative, I want to have DS at a school where I can just happily support what they're doing and be constructive if I need to question something.
