What Is a Job Description?
Definition
A job description is a document that outlines the duties, responsibilities, and scope of a specific role — describing what the job entails, including key tasks, reporting structure, and the role's contribution to the organization.
What Is a Job Specification?
A job specification (sometimes called a person specification) details the qualifications, skills, experience, and personal attributes required of the individual who will perform the job — describing who is needed to fill the role effectively.
Key Differences
- Focus: Job Description focuses on the role itself (what the job involves); Job Specification focuses on the candidate (what qualities/qualifications are needed).
- Content: Job Description includes duties, responsibilities, and reporting lines; Job Specification includes education, experience, skills, and competencies required.
- Use in recruitment: Job Description is often used in job postings to attract candidates; Job Specification is used internally to screen and evaluate candidate fit against required criteria.
Why Both Documents Matter for Effective Hiring
- Together, they ensure job postings accurately attract candidates who both understand what the role involves and possess the qualifications needed to succeed in it.
- Provide a clear, objective basis for screening and interview evaluation criteria.
- Help set accurate compensation benchmarking, since role scope and required qualifications both influence appropriate pay levels.
How to Write Effective Job Descriptions and Specifications
- Keep job descriptions specific and outcome-focused rather than generic task lists
- Distinguish clearly between 'must-have' and 'nice-to-have' qualifications in the job specification
- Regularly review and update both documents as roles evolve over time
Job Description vs Job Specification: Frequently Asked Questions
Are job description and job specification usually combined into one document?
In practice, many organizations combine both into a single job posting document, though formally they represent distinct components — the description of the work itself and the specification of the ideal candidate.
Which document should be used to write a job posting for a job board?
Most effective job postings blend elements of both — using the job description to explain what the role involves and attract genuine interest, and the job specification to clearly communicate the qualifications candidates need to apply.
