Safe to Use for Hiring
Under the Disparate Impact rule, an employer may not use an employment practice that, even though neutral on its face and applied to all applicants or employees, disproportionately excludes members of a protected category.
TTI SI’s assessments were found not to exclude any protected category, allowing users of our assessments to identify the best individuals for the job, as part of their hiring process.
