The child must be a full time student. The IRS defines a full time student as:
To qualify as a student, your child must be, during some part of each of any 5 calendar months during the calendar year:
1. A full-time student at a school that has a regular teaching staff, course of study, and regular student body at the school, or
2. A student taking a full-time, on-farm training course given by a school described in (1), or a state, county, or local government.
The 5 calendar months need not be consecutive.
So your answer depends on how many months during 2016 the child was a full time student.
