Wonderlic, Inc. is a human resources services company headquartered in Vernon Hills, Illinois, with a workforce of 51 to 200 employees. The company develops assessments that combine cognitive ability, motivation, and personality data to generate a job-specific fit score designed to match the right people to the right roles from the start. These tools support data-driven decisions across hiring, onboarding, and employee development throughout the employee lifecycle, and Wonderlic claims the assessments are six times more predictive than resumes. The product suite has evolved over time, including the launch of Wonscore 2.0 in 2018 and partnerships such as with Vervoe in the same year. In 2021 Becca Callahan was named chief executive officer, the first non-family member to hold the role; in 2025 the company was recognized as a Market Leader by Global Career Finder.
