Numerical Data Interpretation Test (NDIT™)

Numerical reasoning is an important skill for many work settings including executive, managerial, supervisory, professional, sales, administrative, and technical roles across most industry sectors. A job analysis will identify what job duties require numerical reasoning. NDIT™ is appropriate for jobs where data interpretation is used frequently or on critical job tasks.

The content for item-banked tests undergoes the same rigorous development and review process as items for a fixed test form. While a fixed test form only has a set number of items equal to the total test length (21 items), the item-banked version has over 100 unique items. Item-banked tests also have more sophisticated item delivery rules to ensure consistency among test administrations such as total word count, variation in the item stimulus (e.g., bar graphs, data tables), and data technique (e.g., costs, revenue, percentages, and ratios). Both item-banked tests and fixed tests ultimately express candidate scores as a percentile rank.

Scores are presented on the candidate’s profile report in the form of a percentile rank and other commonly used standardized scores. The candidate score is displayed as a midpoint percentile rank where the average score is at the 50th percentile. A candidate who scored at or above 65% of the individuals in the normative group on the NDIT™. Candidate raw score, ability score, and percentile rank are available in the administrator’s status/score report dashboard. Administrators may show or hide scores according to their preference by selecting the link under the search field.

Standardized scores (T-scores, STANINE, and STEN scores) can be combined, such as NDIT™ results with other TalentLens' ability test results, to obtain a more complete profile. From a practical perspective, standardized scores meet multinational companies’ requirements, which vary according to local law and preference. However, all TalentLens profile reports also include a candidate percentile rank score. You can continue to use this score to make comparisons in the process of making hiring decisions.

Number Correct, T-score, STANINE score, and STEN score are all reported in the Additional Technical Information section of the candidate’s profile report. Item-banked tests produce a theta score (ability score) that takes into account the difficulty level of each item; therefore, number of correct responses (raw score) should not be used to make hiring decisions. Rather, use the percentile rank or a standardized score because these scores take into account the item-difficulty differences of the administrations.
