Measure numerical reasoning because data is useless without the skills to analyse it

Numerical Data Interpretation Test (NDIT™)


Numerical reasoning is one of the most important skills in today’s data-driven workplace. The NDIT goes beyond a candidate’s typical math skills to identify their ability to manipulate and interpret numerical information from reports, charts, tables, or dashboards. The US Department of Labor’s O*NET database rates these skills as “important” for nearly 300 jobs ranging from sales managers to executives. In today’s data-driven economy, numerical reasoning isn’t just for the finance department anymore.

Designed in consultation with recruiters and human resource professionals, NDIT meets psychometric standards for reliability and validity. NDIT items are face valid or work relevant which improves the testing experience. Because real-world math is not multiple choice, the free response items on NDIT require test takers to calculate their response, unlike with a multiple choice item.
