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.
Many job seekers consider job descriptions a valuable screening tool. Conveying job expectations and requirements in a written job description can attract qualified and interested candidates. Inappropriate language used in job descriptions reveals discriminatory or inappropriate phrases and offers a quick indicator that an individual may want to apply elsewhere. For example, an employer should avoid citing standards that may unnecessarily screen out particular groups such as individuals with disabilities. In contrast, a description written in a respectful tone with appropriate etiquette may encourage an individual to apply.
