It seems to be all over the map! Some schools seem to expect them to come in already reading a few words, others are thrilled if they show up knowing their colors ...
We weren't given explicit "here's what she should know" information when my daughter started kindy last month, but I would say that a kid who came in not knowing colors, shapes, how to recognize all the letters of the alphabet and what sounds the letters make, how to count to 10, and how to hold a pencil or crayon would be "behind." But I imagine most normal five year olds would catch up quickly on those, if he came in not knowing them. They aren't expected to be able to read or do addition or anything like that; so far they're working on letter recognition, improving their printing, recognising the concepts of "less" and "more" -- stuff like that. Plus listening and paying attention and not hitting or wandering around the classroom.
