Reading at 3 isn't normal
But that doesn't mean it's bad by any means.
Apparently I learned to read at 3 and I have loved reading ever since. My son started at 3 but wasn't much interested until about 4 1/2. At 4 1/2 he picked up reading very fast and went from lvl 1 readers to 2nd grade level in about 3 months. He still lacks the interest in reading bigger chapter books but he will read anything and everything all the time.
That being said in his K class they are working on letters and numbers. Each week is a new letter (they did go over all the letters in the first 6 weeks but now they focus on a letter each week). He enjoys the songs they sing and sometimes the crafts they do for each letter but thankfully she has him doing harder worksheets in phonics group and whatnot.
Definitely sit in on a K class or 2 (each school could be very different so it might be worth checking out a few) and if you think your son will need more start talking to the school before he gets to K. I didn't do so and somewhat regret not having a few things in place before now.
From what I can see if K is 1/2 day it tends to go ok for advanced/gifted kids. If it's full day then it can be more of a problem. I'm worried about next year when my 'advanced' 4 yr old goes to K since it may be full day next year. I guess I'll get a plan in place for her when we get one in place for my son for 1st grade, lol.
