The data dictionary says that completed_eleventh_grade field allows null. However, in practice no applications seem to have that value. Can you confirm whether its possible?
It appears that even applications where the question is not presented (applicant is already graduated or hs country is not US), the value will be false (as opposed to empty). This means high school status can be graduated but completed eleventh grade will still be false. Is this a bug or are we expected to disregard the completed eleventh grade value dependent on the value of other fields?
