The right reasoning tests, combined for each role.
A cognitive ability test measures how well people reason, learn and solve problems, often called general mental ability. An aptitude test focuses on one ability, such as numerical or mechanical reasoning. Edstellar combines both into a battery built for each role, around four principles.
Job analysis first
Each test is chosen because the reasoning it measures matters in the role.
The right reasoning areas
Verbal, numerical, abstract or logical reasoning, critical thinking or mechanical reasoning, combined into one battery for the role.
Relevant norm groups and cut-offs
Scores are compared with a suitable comparison group, and any cut-off score is calibrated for the role.
One part of the picture
Cognitive results sit alongside structured interviews, work samples and other evidence, never on their own.
Edstellar cognitive ability tests that make hiring clearer and fairer.
Edstellar’s cognitive ability and aptitude testing gives hiring managers and HR a consistent, job-relevant view of reasoning ability, so selection, promotion and succession decisions build on objective evidence.
Find fast learners
Learning ability and learning agility show who will pick up new roles, systems and ideas quickly.
Screen large applicant pools consistently
Online pre-employment aptitude tests give every applicant the same standard, so candidate screening for graduate and high-volume hiring stays consistent.
Match reasoning to the role
Numerical reasoning, verbal reasoning, critical thinking or mechanical reasoning tests focus on the reasoning skills each role actually uses.
Compare candidates objectively
Standardized scoring and relevant norm groups show how each result compares with a suitable group.
Spot potential for bigger roles
Cognitive measures add evidence to promotion and succession decisions, alongside performance and leadership data.
Fair, defensible decisions

Cognitive ability and aptitude testing FAQs.
A cognitive ability test, also called a cognitive assessment, measures how well a person reasons, learns and solves problems, often called general mental ability. Common areas include verbal, numerical and abstract reasoning. Edstellar uses validated cognitive ability tests as one part of hiring, promotion and succession decisions.
A cognitive ability test gives a broad view of reasoning and learning ability. An aptitude test focuses on one specific ability, such as numerical reasoning, critical thinking or mechanical aptitude. Edstellar often combines both in one battery, matched to the role.
Depending on the role, Edstellar uses tests such as Logiks, DAT Next Generation, RAVEN'S Adaptive, WATSON-GLASER III, NDIT and BMCT-II, and Talogy Caliper where cognitive and personality measures are combined.
Cognitive tests suit roles where reasoning skills, learning and problem solving are job relevant, such as graduate, analyst, manager, finance and technical roles. Mechanical reasoning tests such as BMCT-II are used only where mechanical comprehension matters in the role.
Yes. Online aptitude tests such as Logiks and DAT Next Generation work well as an early-stage screen for graduate and high-volume hiring, with cut-off scores calibrated to the role and paired with structured interviews.
Edstellar uses tests only where they are job relevant, documents that relevance, compares scores with suitable norm groups, provides accommodations where required and reviews results across candidate groups. Cognitive results are always combined with other evidence, such as structured interviews and work samples.
Cut-off scores are calibrated for each role, using the right norm group and the level of reasoning the role requires, and they are reviewed over time so they stay fair and useful.
Yes. Measures such as Talogy Caliper add evidence on potential for bigger roles, alongside performance data, leadership assessment and development center results.
Yes. Cognitive and aptitude tests run online across locations, so every candidate follows the same format. Adaptive tests such as RAVEN'S Adaptive adjust to each candidate's responses.
Test data is collected only for the agreed purpose, access is limited to agreed stakeholders, and reports are shared under the confidentiality terms set at scoping. Edstellar holds ISO/IEC 27001:2022 certification for information security management.
Cost depends on the number of candidates, the tests used, how many roles need their own battery, and how much calibration, reporting and feedback you need. Edstellar scopes each program before quoting, so you pay only for what your decision requires.
