It's not all that easy to give advice to somebody you don't know. So basically .... this is what I think I would say to myself if going back in time were an option.
Education is better off being chosen for what it is, rather than for what another form of education isn't. It's a bit like emigrating. You stand a better chance of making a real go of it when you are running to a place for its own sake, rather than running from somewhere else. Don't let the list of negatives of "choice Purple" be such a focus that you end up in "choice Orange" with unrealistic expectations, in part because of "next door's greener grass" issues.
Make the child you actually have the priority.
Other people's children are other people's children and their needs, quirks and "happiness buttons" may bear little resemblance to your own kid. Examples are interesting. But not necessarily indicative of your own child's "round peg" qualities. Really look at the kid you have. And remember they can change a lot as they grow.
Be prepared to have to face making a new change in the future if your child's needs change, or you discover an earlier choice isn't such a good fit after all. It really helps if you haven't slagged off the "new" choice to everybody you know, with kiddo earwigging, as part of defending original choice. Because it's embarrassing. And you can feel like a twerp.
Be ruthless and use more head than heart. Again, it's a bit like emigrating. Don't just look at all the lovely, exciting, fabby things the preferred destination offers. Go check out the slums. Take note of the degree of bureaucracy. Find out if there are any dodgy political parties which enjoy a bit more support than you are comfortable with. Don't listen solely to what the welcome committee has to say. Find the dissenters, the underclass. Talk to them too. If you can't find them, consider that nothing is perfect, nothing makes all of the people happy, all of the time, so ask yourself how and why the disgruntled are so difficult to find.
What you discover may take of the shine to the extent you need a rethink. Or it may just be the reason why you are able to chose exactly the right "good area" for you to make a happy "first educational home" right from the start. Rather than having to lurch from city, to town, to village and back again ...wondering when you'll find a good fit that survives the honeymoon period.
Be brutally honest about your resources. Resources include things like time, energy, patience, resilience and cold hard cash. No one single choice is free. It will always cost something. Make sure you have enough of the somethings your choice tends to guzzle, so fuel doesn't run low and you find yourself grinding to a halt. With no jerry can. And a very long walk ahead of you. Just as it starts raining.
Trial runs are your friend. You'd take a car for a test drive. Test drive an education. The less of a big deal you make to everyone (inc. kid) about this being your forever car, cos it's the best car there is and all other cars are shit, the better your chances of not feeling like a prat if you end up handing it back in to the dealer, cos it makes a funny noise every time you turn left and the boot has some kind of weird anti-Tardis quality going on.
Surround yourself with people you genuinely like for who they are. Avoid "ghettoising" yourself and your child by accidentally letting your circle become dominated by "A Thing" you have in common. Cos sometimes that can mean a smaller "pool" to pick from, which can lead to compromises too far. Be especially careful in that regard when it comes to the child. Sometimes a parent feeling in good company can lead them to overlooking the "mates" compromises too far that the smaller party is having to make.
Bear in mind that an educational choice can sneak up on you in terms of trying to burrow into your sense of identity. Be you, and treat your choice as a tool. Don't let your choice turn you into a tool of validation of said choice. It sort of helps you be the boss of the choice, rather than the other way around.
Other people, even if they don't agree with the way you are leaning, perhaps especially if they don't agree with the way you are leaning, are still worth listening to. You may know your own kid best. But you might not know absolutely everything about every form of education best. And ..parents can get tunnel vision too, however much they love their children. Listening to disagreement non defensively doesn't have to mean choosing different. But it may throw up ideas and issues you might not have given so much weight to otherwise. That may mean you make the same choice, but better equipped to be good at it.
Regard people who use "just" with grave suspicion. "Just" can be a seductive minimiser of very valid concerns in terms of roadblocks. Unless your life, kid and circumstances are carbon copies of the "just" people, "just" for you may entail many miles to be travelled, a small bleeding fortune having to be spent, giving up a "non negotiable" because logistically you couldn't make it work where you live and maybe even a kid who is nowhere near as happy as they could be. If you think you've spotted a potential roadblock, taking a glass half empty stance when considering the extent to which you can get round it .....may be a better bet in terms of finding truly workable solutions, rather than band-aids.
Bear in mind that none of the above is HE specific. It can apply to all and every form of eduction. It's more "picking education" advice than specific "picking HE" advice. I've done a lot of education picking. Not of all of it good picking.
