You also ask whether it is legal to ask the applicant's age and use of medications to allow for variants in his/her handwriting." The letter advised that in this circumstance, it was illegal under the Americans with Disabilities Act of 1990 (ADA) to ask a job applicant whether he or she is taking any medications, and also advised that asking an applicant for his or her age "allegedly to allow for variants in analyzing his/her handwriting" was not a "per se" violation of the Age Discrimination in Employment Act of 1967 (ADEA), but could be significant evidence of age discrimination. The letter also said that there was no judicial guidance on "whether a policy of excluding applicants based upon their handwriting has an adverse impact on a protected group" under the ADA, ADEA, or Title VII of the Civil Rights Act of 1964.

The most substantial reason for not using handwriting analysis in the employment process is the absence of evidence of a direct link between handwriting analysis and various measures of job performance. The use of graphology in the hiring process has been criticized on ethical grounds and on legal grounds in the United States.
