Writing Effective Job Descriptions and Person Specifications

Posted on 16/11/2021 by Gemma Hannington

Writing job description and person spec

It is important to have a detailed job description to help attract the best talent to apply to your role. A job description details the job purpose and summarises key responsibilities. Typically, these include a person specification, a profile of your ideal new employee, including skills and experience required or ideal to have. It is an opportunity for you to showcase the role and the impact this person can make with your organisation. 

Why should you bother?

Writing a detailed specification forces you to think about exactly what skills and experience is required for your role and the type of person you want for the team. Giving your recruitment consultant a comprehensive brief will allow them to work more effectively and quickly in finding you the perfect candidate.

Specifications also give candidates a better idea of exactly what you are looking for. This can help to weed out inappropriate applications from people who might be suitable on paper, but not actually that interested in the role. They also help to manage the expectations of successful new employees and to avoid situations where they feel they have been misled about the exact nature of the role.

You can use the specifications as a checklist for evaluating CVs and in interviews, which will save you preparation time and make sure you don’t miss anything.

Writing specification can make you think about how your department works and provide you with an opportunity to shift responsibilities around to maximise efficiency.

Specifications are also useful after the vacancy has been filled, as they can help to assess a new recruit's performance and to determine their future training needs.

Things to bear in mind before you start

Before beginning, we recommend designing your role to ensure the best use of resources and to improve staff attraction, retention, and wellbeing. The role design process fully defines what the job involves, including duties and responsibilities, how the job relates to the organisational structure; goals, principles and objectives, and what support, resources and training the employee will require and receive. You can find our 6 simple steps to successful role design here

Be as specific as possible about the responsibilities of the job, including any deadlines for delivery and measurements of success.

Leave room for flexibility within the job specification and make it obvious if the role is likely to change or grow in the near future. This helps to avoid employees resenting taking on responsibilities not in their original job description.

Be careful with your wording, eg is a qualification really required or would someone who is Qualified by Experience (QBE) still be suitable?

Consider your essential requirements, are your essentials essential?

It is essential not to discriminate on grounds of gender, age, ethnicity, sexuality or health, so avoid any inappropriate requirements, eg “must have x years’ experience” or words such as “dynamic” or “mature”.

What should you include?


You can download a free template with everything to include in both a job description and person specification here. This is a reusable template that can be tailored for each role. 

A job specification should include:

A person specification should include:
