This list is definitely ideal, but having had a SEN child, who got there a little later, a lot of it can be worked round, if he's not quite there.
toileting including wiping - try to get them to poo at home, and except there will be skids some days
getting changed into PE clothes and back into uniform - look at ASDA easy on uniform. It's all velcro or elastic if he's not quite there with buttons
hanging his things on a peg - make sure everything has a big hanging loop.
putting shoes/wellies on the right feet - pick easy shoes & put half sticker inside each, line up to get right way
eating independently using cutlery - If he's not there by September, a term of eating sandwiches on pasta day isn't the end of the world
turn taking - focus on this & social/ play skills
holding a crayon/pencil - yes but just colouring in fun, not letter practice
recognising his name written down - would be handy, actually one of the easyer ones
putting sun cream on his face - always just put it on before mine go in & use a wide brim hat
Coat - get one with zelcro over the zip, the velcro will be enough to keep it on.
