I should’ve said:
The standard process is to be sent to Adult school if one did not complete high school graduation requirements by the end of school year in which the student turns 18 yrs of age.
Every school district here, local to us, has an associated Adult education school. But also it is not preferable to go there. I can imagine that they would barely be providing anything and like the alternative independent study school within district, this school would also be yet another check mark item. The good news is that my son is determined to complete high school on schedule with the class of 2020, perhaps without honors/APs, his English teacher has talked to him into it too. I think it is doable, we will see.
