A job specification could be considered a more precise job description that details the exact educational degrees, experience, skills, and requirements for a role. In most cases, these terms are used interchangeably and nearly always describe the same document.
According to the ADA, an employer may not ask disability-related questions and may not conduct medical examinations until after it makes a conditional job offer to the applicant (EEOC, 1995). An individual, as an applicant or a current employee, may wish to disclose that s/he has a disability and needs an accommodation, but is uncertain whether disclosure is possible or advisable. Including a brief and accurate statement in the job description about the employer’s responsibility and the individuals rights may help initiate the interactive process between an employer and an individual with a disability. If an individual is qualified to perform essential job functions except for limitations caused by a disability, the employer must consider whether the individual could perform these functions with a reasonable accommodation. An employer is not required to reallocate the essential functions of a job as a reasonable accommodation.
