Is my newly-graduated student, now working, a qualifying child?

My 23-year-old daughter was a full-time graduate student until last May, and then took one last class in July and finished in August, getting her degree.   She began renting her own apartment on July 1 (we paid for the first month), and she started a full-time job on July 8.    Given this, is she a "qualifying child"?
