I think somewhere in between. But zero reply to your email--after a two days, say--that's not cool. Hopefully someone's just waiting to confer with another and dropped the ball on a quick reply. It really is amazing how much hugely time consuming work teachers can have, especially at the start of school. I'd say a week or so is very reasonable. Hopefully they are conferring about placement and will update you soon. Of course you could have a teacher who is taking her sweet time--what's the goal with the test? Subject acceleration? A whole new class he'd transfer to? Or just an accelerated group? I know they teach routines for a few weeks at our school and then really differentiate, but are all doing the same easy stuff as they learn classroom routines. It seems like forever but after seeing the whole class in action I get it better now.
