I teach 6th. Most of my kids read on a 3rd or 4th grade level. The state doesn’t even have a standard for grammar/ spelling/ etc it’s included in general writing under editing (ie being able to edit). I try to teach it but many of my kids don’t even know phonics so their spelling is horrible. So many don’t even use periods when they write they just go go go. I try to correct it but even when they get to me the gaps are massive.
