85 to 115 is average.
Around 80 is considered the range for mild intellectual disability.
Below 70 would be considered developmental.

BUT, when there are huge discrepancies in IQ test scores, any sort of conclusion has little relevance. Say you have a verbal IQ of 75 and performance IQ of 125. You can't add them up and come up then divide by 2 and then conclude you have an overall IQ of 100. There is no way that you are average. You have a huge discrepancy in the two scores and that typically points to a disorder or LD of some type. Good practitioners in this instance wouldn't state an overall IQ.

IQ is supposed to measure intellectual potential. Funny thing is that IQ can change over time and sometimes you see significant swings in scores. One possible explanation is because the degree of impairment of a disorder can change over time.

Or maybe the person learns more, and more neurons make connections.
