Key Differences Between Job Specification and Job Description

When it comes to hiring, it’s important to know the difference between a job description and a job specification. While they may sound similar, each serves a unique purpose in the recruitment process. A job description explains the duties and responsibilities of the role, while a job specification outlines the skills, qualifications, and experience a candidate needs. Understanding both can help employers attract the right applicants and make better hiring decisions.

In this article, we’ll explore what job descriptions and job specifications mean, how they differ, how they work together in recruitment, and share examples to make things clearer.

What is a Job Description?

A job description is a formal document that outlines the roles, responsibilities, and duties associated with a specific job within an organization. It serves as a communication tool between the employer and the prospective employee, offering a clear understanding of what is expected of them once they join the organization.

At its core, a job description includes vital information such as the job title, the department the role belongs to, key duties, working hours, and the reporting structure. It also describes the working conditions and any necessary tools or equipment. This document is usually crafted after conducting a thorough job analysis, which helps identify the necessary knowledge, skills, and responsibilities required to perform the job.

Job descriptions help to clarify the purpose of the role within the company and establish expectations for employees, making them an essential element of the recruitment process. They help attract candidates by detailing exactly what the job entails, allowing applicants to evaluate if they are the right fit for the role.

What is a Job Specification?

While a job description provides an overview of the role itself, a job specification focuses on the qualifications, skills, experience, and personal attributes required from the candidate to succeed in the role. This document typically follows the job description and provides a more detailed look at the ideal candidate’s background.

Job specifications can include various criteria such as educational qualifications, required certifications, technical skills, experience, and any physical or psychological attributes deemed essential. For instance, a job specification might specify that an applicant needs a bachelor’s degree in a particular field or experience with a specific software tool.

Unlike job descriptions, job specifications are not meant to outline the tasks of the role. Instead, they define the competencies and qualifications necessary for an individual to meet the expectations described in the job description. Job specifications provide clarity on the type of candidate needed to perform well in the role and ensure that recruiters select individuals who possess the right mix of abilities and experience.

Main Differences Between Job Description and Job Specification

While both job descriptions and job specifications serve critical functions in recruitment, their key differences are apparent in several areas:

Nature

The nature of a Job Description revolves around outlining the specific duties, responsibilities, and scope of the role within an organization. It provides a clear understanding of what is expected from an employee on a daily basis, such as the tasks they will be responsible for and how their role fits into the overall organizational structure. In contrast, a Job Specification is focused on identifying the qualifications, experience, and personal traits a candidate must possess to succeed in the role. It highlights the skills and attributes needed to meet the demands outlined in the job description, ensuring the right fit for the position.

Focus

A Job Description primarily focuses on the role itself—detailing the job’s responsibilities, tasks, and any specific requirements that need to be met. It serves as a guide for candidates to understand what the job entails and how they will be contributing to the organization. On the other hand, a Job Specification concentrates on the candidate’s qualifications, skills, and experience. It outlines the key characteristics and capabilities an ideal applicant must have in order to perform the duties mentioned in the job description effectively.

Content

The content of a Job Description is comprehensive, covering elements such as the job title, department, key duties, working conditions, reporting relationships, and sometimes even salary ranges. It provides all the relevant details about the position itself, helping both recruiters and candidates understand the role’s expectations. In contrast, a Job Specification contains more specific information about the required qualifications, such as educational background, relevant work experience, technical competencies, and physical or personal traits needed for the role. It is more focused on the candidate’s suitability for the job rather than describing the job itself.

Purpose

The purpose of a Job Description is to clearly define what the employee will be doing in their role, providing an outline of the day-to-day tasks and responsibilities. It ensures that the employee understands their position and the expectations from their role. Conversely, the Job Specification serves to specify the attributes and qualifications an ideal candidate should possess to perform the job successfully. It sets the criteria that guide the hiring process, ensuring that candidates meet the necessary standards before being considered for the position.

Usage

Recruiters use a job description to attract applicants by clearly outlining the job’s duties, expectations, and work environment. It plays a key role in job advertisements and helps kick off the recruitment process. In contrast, they use a job specification to screen candidates. It helps them check if an applicant has the right qualifications, experience, and traits to match the role before moving forward in the hiring process.

Their Role in the Hiring Process

Both job descriptions and job specifications are fundamental in the recruitment process, but they serve different purposes. Job descriptions act as the initial introduction to the role, helping candidates understand the responsibilities they would take on if hired. They also provide a benchmark for interviewers to assess whether a candidate’s skills align with the job requirements.

On the other hand, job specifications serve as a screening tool. When reviewing candidates, recruiters use the job specification to determine whether the applicant possesses the required qualifications, experience, and skills. By doing so, they can quickly identify the most suitable candidates and avoid wasting time on individuals who don’t meet the necessary criteria.

By combining job descriptions and job specifications, organizations can create a detailed and comprehensive hiring profile. This approach ensures that candidates are evaluated against a clear set of expectations, improving the likelihood of selecting the right fit for the role.
