The Science Behind Pre-employment Screening: How Tests and Assessments Predict Job Performance


Scientific pre-employment screening is a standardized way of gathering candidates’ data objectively during hiring. It uses established scientific principles backed by independent research over the years to automate actions that streamline your hiring process.

Assessments will save you time and resources. They use AI-powered systems to score results that produce accurate performance predictions. These provide reliable recommendations based on detailed reports that feature requisite skills and abilities to eliminate the guesswork in the hiring process.

What Is The Science Behind Pre-employment Screening?

Quality tests and assessments must scientifically achieve two things.

  • Provide valid measurements
  • Procure successful new hires

Furthermore, they must also satisfy two criteria:

  • Be consistently reliable in measuring the traits they purport to measure
  • Measure attributes related to job performance

Below are five principles of pre-employment assessments you must follow to meet the required threshold:


1. Stems From a Solid Job Analysis

Job analysis involves identifying an employee’s vital tasks, skills, knowledge, and abilities required to perform a specific job optimally. High-quality pre-employment assessment platforms use comprehensive job analysis data from various sources to create pre-made test templates you can benefit from. The data forms the backbone determining the skill, knowledge, and ability sets for multiple occupations to streamline the hiring process.

2. Based on Holistic Evaluation

Many assessment tests combine into a single job-related test to create these examinations. It allows recruiters to measure potential employees’ cognitive abilities, personality, skills, past behavior, and knowledge to select the right candidate for the job. The approach guarantees test fairness and reliability while cushioning employers from worrying about using wrong tests or missing valuable information while recruiting new individuals.

3. Design Anchored on Reliability

Proper measurement is above par if you can repeat it consistently with the same results. You cannot rely on any examination that produces alterations when repeated. Such a test that returns varying results is useless. Pre-employment assessment platforms avoid these shortcomings by applying accepted statistical methods to improve and regularly evaluate reliability.


4. Simulates Real Life Job Scenarios

Tests that simulate job-related environments create the best impression on candidates. The principle, known as face validity, is widely recognized in employment circles. The format evaluates cognitive ability, skills, and knowledge among test takers. It enacts scenarios that require candidates to prove how they would handle customers, workers, and supervisors while performing daily job-related tasks excellently.

5. Requires Constant Evaluation to Improve Validity

Validity is the ability of a test to fulfill its purpose. New dynamics in the job market may compromise previously valid tests. The world is dynamic. In the workplace, trends and technological advancements change the way of doing things every day. What worked yesterday may not be relevant today, hence the need to compare individual performance and data from test scores to gauge them. Clients sometimes share this information with assessment platforms that use it to improve each test.
