Understanding adverse impact featured image

Building a diverse and inclusive workplace starts with fair hiring practices. While policies may be created with the best intentions, they can occasionally lead to unintended bias, known as adverse impact. This is what occurs when certain groups are unintentionally disadvantaged in the hiring process.  By understanding how adverse impact happens, how it differs from intentional discrimination, and how to monitor and adjust for it, you can continuously improve fairness in your hiring process. In

HR professionals often face the challenge of hiring for diverse roles, many of which they might not be intimately familiar with. In a week, you might have ongoing processes for a software engineer, a marketing coordinator, and a graphic designer. It can be difficult to know, understand, and apply criteria and standards that are a) role-specific and suited to your organization and b) broad enough to have universal relevance. That’s where TestGorilla assessments step in, helping you evaluate both

However, it's important to ensure that the tools you use are precise, accurate, and valid.  Test validity is a complex concept that encompasses different areas like criterion validity, construct validity, and content validity. Content validity is a type of validity that helps you determine whether your tests adequately cover the relevant knowledge and skills you aim

Cognitive ability tests are a great tool for identifying top candidates when used appropriately. However, while they certainly are popular and useful, tests of cognitive abilities should be used carefully.

This blog will walk you through some best practices, based on the latest scientific insights,  for
