Honestly, my DD almost 5, is spelling. Not using a formal spelling program. She reads cvc and cvcc words well. So she sounds out the word and spells it to me. Maybe 2 or 3 words. Only done orally and just when I think of it. Which is a few times a month, maybe.
A formal program won't happen till 1st or 2nd grade.
I guess what I'm trying to say is it depends on the kid and where their at.
