[Code of Federal Regulations] [Title 29, Volume 3] [Revised as of July 1, 2004] From the U.S. Government Printing Office via GPO Access [CITE: 29CFR541.304] [Page 214] TITLE 29--LABOR CHAPTER V--WAGE AND HOUR DIVISION, DEPARTMENT OF LABOR PART 541_DEFINING AND DELIMITING THE TERMS ``ANY EMPLOYEE EMPLOYED IN A Subpart B_Interpretations Sec. 541.304 Primary duty. (a) For a general explanation of the term ``primary duty'' see the discussion of this term under ``executive'' in Sec. 541.103. See also the discussion under ``administrative'' in Sec. 541.206. (b) The ``primary duty'' of an employee as a teacher must be that of activity in the field of teaching. Mere certification by the State, or employment in a school will not suffice to qualify an individual for exemption within the scope of Sec. 541.3(a)(3) if the individual is not in fact both employed and engaged as a teacher (see Sec. 541.302(g)(2)). The words ``primary duty'' have the effect of placing major emphasis on the character of the employee's job as a whole. Therefore, employment and engagement in the activity of imparting knowledge as a primary duty shall be determinative with respect to employment within the meaning of the exemption as ``teacher'' in conjunction with the other requirements of Sec. 541.3.
