This St. Patrick’s Day you can hope the luck of the Irish is on your side or follow a rainbow in hopes of it leading to the perfect candidate for your organization. But we all know, hiring decisions take much more than luck! One tool in the HR professional’s tool box is a pre-employment assessment or candidate profile. Pre-employment tests can help a company’s hiring process by increasing the likelihood of hiring candidates who will perform well on the job.

An effective assessment provides major benefits to a company, including:

Higher productivity
Increased employee retention
Improved employee morale
Reduction in costs associated with turnover (hiring and training costs)
Increasing the defensibility of the hiring process by using objective data

When properly implemented, pre-employment tests provide the most accurate means of predicting performance because they measure the candidate’s capacity to perform well at a particular job. Research has shown that cognitive aptitude tests, for example, are much more accurate predictors of job performance than job interviews and previous work history.

Having accurate data in front of you leads to more successful and efficient decisions. Improving the success rate of your selection methodology will lead to higher productivity, better employee retention, and a reduction of the costs associated with turnover. What an amazing snowball effect!

One study compared employees’ pre-assessment scores with their hourly sales volume at a clothing store. The employees who received high scores on the test sold, on average, $106.35 of goods per hour, while those who received low test scores sold only $83.27 per hour. Incorporating pre-employment tests into its selection process resulted in a 28 percent increase in sales productivity.

Once your organization has made the decision to include pre-employment tests in the hiring process, the next step is finding a partner to help design and implement a professionally developed and properly validated employment tests. Tests are an effective screening tool only if they measure the knowledge, skills, and abilities that will be required for a particular job. In other words-to be a valid predictor of performance, a test must measure job-related competencies and abilities. The test must also be EEOC compliant.

It’s also important to remember, the pre-employment test is just one piece of the hiring puzzle. It can give HR professionals additional (and accurate) data to make great hiring decisions. Other factors such as references, resumes and interviews are invaluable components to this process as well. When used together, the results are powerful. Increased productivity, retention, and a reduction of costs can have a major affect your organization’s bottom line and can ultimately change your business model.
