Am I considered a full-time student?

To qualify as a student, the person must be (during some part of each of any five calendar months of the year):

1. A full-time student at a school that has a regular teaching staff, course of study, and a regularly enrolled 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 by a state, county, or local government agency

Note: The five calendar months do not have to be consecutive. 

More detailed information can be found in the Chapter "Personal Exemptions and Dependents" of Publication 17, Your Federal Income Tax.

A child’s student status determines whether parents or guardians can continue to claim the qualifying child on their tax return until they turn 24 years old.   

A "qualifying child" means:

• They're related to the person claiming them
• They aren't claimed as a dependent by someone else
• They're a US citizen, resident alien, national, or a Canadian or Mexican resident
• Unmarried or, if married, not filing a joint return or only filing a joint return to claim a refund of income tax withheld or estimated tax paid
• They're under the age of 19 (or 24 for full-time students)
• There’s no age limit for permanently and totally disabled children
• They lived with the taxpayer for more than half the year (exceptions apply)
• They didn't provide more than half of their own support for the year
