Tough question.
His spelling on spelling tests is almost always 100%. When spelling while writing he misspells but uses phonetically correct substitutions. Kight for kite. He just loves that igh makes the long I sound. He was taught in K to just write and not worry about spelling and now we are backtracking trying to undo that idea. He remembers that he was told not to worry about spelling and tells me its ok. Or at least he used to. He is just now asking for correct spelling. When he texts or emails ( with the help of computer spelling) I can't always tell if its him or my husband texting. He uses advanced vocabulary. He starts to type the word he wants and when he sees it he knows which the correct word is.
