(a) Full-time students. A full-time student for the purpose of this subpart is defined as a student who receives primarily daytime instruction at the physical location of a bona fide educational institution, in accordance with the institution's accepted definition of a full-time student. A full-time student retains that status during the student's Christmas, summer and other vacations. An individual who was such a student immediately prior to vacation will be presumed not to have discontinued such status during vacation if local law requires his/her attendance at the end of the vacation. In the absence of such requirement his/her status during vacation will be governed by his/her intention as last communicated to his/her employer. The phrase in section 14(b) of the statute “regardless of age but in compliance with applicable child-labor laws,” among other things, restricts the employment in a retail or service establishment to full-time students who are at least 14 years of age because of the application of section 3(1) of the Act. There is a minimum age requirement of 16 years in agriculture for employment during school hours and in any occupation declared hazardous by the Secretary of Labor (subpart E-1 of part 570 of this title.) In addition, there is a minimum age restriction of 14 years generally for employment in agriculture of a full-time student outside school hours for the school district where such employee is living while so employed, except

(b) Bona fide educational institution. A bona fide educational institution is ordinarily an accredited institution. However, a school which is not accredited may be considered a bona fide educational institution in exceptional circumstances, such as when the school is too recently established to have received accreditation.

(c) Retail or service establishment. Retail or service establishment means a retail or service establishment as defined in section 13(a)(2) of the Fair Labor Standards Act. The statutory definition is interpreted in part 779 of this chapter.

(d) Agriculture. Agriculture means agriculture as defined in section 3(f) of the Fair Labor Standards Act. The statutory definition is interpreted in part 780 of this chapter.

(e) Student hours of employment. Student hours of employment means hours during which students are employed under full-time student certificates issued under this part and is distinguished from hours of employment of students.

(f) Employer. Section 519.4 permits an agricultural or retail or service establishment employer to employ not more than six full-time students at subminimum wages on forwarding an application but before certification. For this purpose, the term employer looks to the highest structure of ownership or control, and hence may be more than a single retail or service establishment or farm, e.g., the controlling conglomerate or enterprise would be the employer. With respect to public employers who operate retail or service establishments (see 29 CFR part 779), the employer means the highest structure of control such as the State, municipality, county or other political subdivision.
