Student. For purposes of section 151(e) and section 152(d), and the regulations thereunder, the term student means an individual who during each of 5 calendar months during the calendar year in which the taxable year of the taxpayer begins is a full-time student at an educational institution or is pursuing a full-time course of institutional on-farm training under the supervision of an accredited agent of an educational institution or of a State or political subdivision of a State. An example of institutional on-farm training is that authorized by 38 U.S.C. 1652 (formerly section 252 of the Veterans' Readjustment Assistance Act of 1952), as described in section 252 of such act. A full-time student is one who is enrolled for some part of 5 calendar months for the number of hours or courses which is considered to be full-time attendance. The 5 calendar months need not be consecutive. School attendance exclusively at night does not constitute full-time attendance. However, full-time attendance at an educational institution may include some attendance at night in connection with a full-time course of study.
