12.1.1 An employer may request or require additional application materials, such as resumes, CVs, transcripts, or certifications, during an initial employment application, provided that the employer notifies the applicant that the applicant may redact or remove information that identifies their age, date of birth, or dates of attendance at or graduation from an educational institution.

12.1.2 Employers may request an individual to verify compliance with age requirements imposed by law or regulation, or enrollment or membership in a program or organization required for the position, so long as the individual is not required to disclose their "specific age, date of birth, or dates of attendance at or date of graduation from an educational institution on an initial employment application." This includes that an employer may ask:

12.2.1 If an employer claims that it is or was required to verify compliance with age requirements imposed pursuant to or required by a bona fide occupational qualification pertaining to public or occupational safety, it must establish that the challenged practice does indeed effectuate that goal and that there is no acceptable alternative which would better advance it or equally advance it with less discriminatory impact.

12.2.2 If an employer claims that it is or was required to verify compliance with age requirements imposed pursuant to or required by a federal, state, or local law or regulation based on a bona fide occupational qualification, it must establish that the age limit imposed by the law or requirement is reasonably necessary to the essence of the business, and either that:

12.2.3 Whether occupational qualifications will be deemed to be "bona fide" to a specific job will be determined on the basis of all the pertinent facts surrounding each particular situation. It is anticipated that inquiries based on a bona fide occupational qualification will be limited in scope and application.
