Introduction to Job Descriptions and Person Specifications
When businesses need to hire new employees, they can't just put up a sign saying "Help Wanted!" They need to be much more specific about what they're looking for. This is where job descriptions and person specifications come in - they're like a roadmap that helps both employers and job seekers understand exactly what's needed.
Think of it like this: if you were looking for a new phone, you'd want to know its features, what it can do and what you need to use it properly. Job descriptions and person specifications do the same thing for jobs!
Key Definitions:
- Job Description: A detailed document that outlines the main tasks, duties and responsibilities of a specific job role.
- Person Specification: A profile that describes the ideal candidate's skills, qualifications, experience and personal qualities needed for the job.
- Essential Criteria: The must-have requirements that candidates absolutely need to have.
- Desirable Criteria: The nice-to-have qualities that would be beneficial but aren't absolutely necessary.
📄 Job Descriptions
A job description is like a detailed recipe for a job role. It tells you exactly what ingredients (tasks) are needed and how they should be mixed together (responsibilities). This helps everyone understand what the job actually involves on a day-to-day basis.
👤 Person Specifications
A person specification is like a shopping list for the perfect employee. It describes what kind of person would be best suited for the job, including their skills, experience and personality traits.
Components of Job Descriptions
A good job description is like a well-organised filing cabinet - everything has its place and purpose. Let's break down the essential components that make job descriptions effective and useful.
Essential Elements of a Job Description
Every job description should include several key components to give a complete picture of the role. These elements work together to create a clear understanding of what the job involves.
🎯 Job Title & Department
The official name of the position and which department it belongs to. This should be clear and accurately reflect the role's level and function.
💼 Main Purpose
A brief summary explaining why this job exists and how it contributes to the organisation's goals. This gives context to all the specific tasks.
✅ Key Responsibilities
A detailed list of the main tasks and duties the job holder will be expected to perform regularly. These should be specific and measurable where possible.
Real-World Example: Retail Assistant Job Description
Job Title: Retail Sales Assistant - Fashion Department
Main Purpose: To provide excellent customer service whilst achieving sales targets and maintaining store standards.
Key Responsibilities: Serve customers at the till, restock shelves, handle customer enquiries, process returns, maintain visual merchandising standards and work as part of a team to achieve daily sales targets.
Understanding Person Specifications
While job descriptions tell us what needs to be done, person specifications tell us what kind of person can do it best. It's the difference between describing a car and describing the ideal driver for that car.
Building Effective Person Specifications
Person specifications are typically organised into different categories, each focusing on a different aspect of what makes someone suitable for the role. This systematic approach helps ensure fair and thorough assessment of candidates.
🎓 Qualifications
Educational achievements, professional certifications, or training courses that are needed. For example, GCSEs in Maths and English, or a driving licence.
💼 Experience
Previous work experience or situations that have prepared someone for this role. This might include similar jobs, volunteer work, or relevant life experiences.
🧠 Skills & Abilities
Specific capabilities needed to perform the job well, such as communication skills, computer literacy, or the ability to work under pressure.
Essential vs Desirable Criteria
Not all requirements are created equal! Some things are absolutely necessary (essential), while others would be nice to have but aren't deal-breakers (desirable). This distinction is crucial for fair recruitment.
❗ Essential Criteria
These are the non-negotiable requirements. If a candidate doesn't meet these, they simply cannot do the job effectively. For example, a bus driver must have a valid driving licence - there's no way around this requirement.
- Legal requirements (age, qualifications, licences)
- Critical skills for job performance
- Minimum experience levels
- Essential personal qualities
⭐ Desirable Criteria
These are the bonus features that would make someone even better at the job, but their absence wouldn't prevent someone from being successful. They help distinguish between good candidates when making final decisions.
- Additional qualifications
- Extra experience in related areas
- Bonus skills or languages
- Preferred personal qualities
Case Study Focus: Café Assistant Position
Essential: Must be 16+ years old, able to work weekends, basic maths skills for handling money, friendly personality for customer service.
Desirable: Previous experience in hospitality, food hygiene certificate, ability to speak a second language, experience with coffee machines.
This shows how the essential criteria cover the absolute basics needed to do the job safely and legally, while desirable criteria would make someone even more valuable to the business.
The Benefits of Clear Job Documents
Having well-written job descriptions and person specifications isn't just about ticking boxes - they provide real benefits for everyone involved in the recruitment process.
Why These Documents Matter
Good job descriptions and person specifications are like having a clear map when you're trying to reach a destination. They help everyone involved understand where they're going and how to get there.
⚖ For Employers
They help attract the right candidates, provide a basis for fair selection, support legal compliance and set clear expectations for performance management.
👥 For Job Seekers
They help people understand if they're suitable for a role, prepare better applications and know what to expect if they get the job.
⚖ For Fairness
They ensure all candidates are assessed against the same criteria, reducing bias and supporting equal opportunities in recruitment.
Common Mistakes to Avoid
Even with the best intentions, it's easy to make mistakes when creating these important documents. Here are some pitfalls to watch out for:
❌ What Not to Do
- Being too vague about responsibilities
- Setting unrealistic or unnecessary requirements
- Using discriminatory language
- Making everything "essential" when it's not
- Forgetting to update documents regularly
✅ Best Practices
- Use clear, specific language
- Focus on what's actually needed for the job
- Review and update regularly
- Get input from current job holders
- Ensure legal compliance
Legal Considerations
In the UK, job descriptions and person specifications must comply with equality legislation. This means they cannot discriminate based on protected characteristics like age, gender, race, religion, or disability unless there's a genuine occupational requirement. For example, you can't require someone to be under 30 unless there's a specific legal reason related to the job itself.
