Test of Everyday Reasoning-Numeracy (TER-N)

Test of Everyday Reasoning-Numeracy (TER-N)

Test of Everyday Reasoning - Numeracy, Grades 9+

Critical thinking and quantitative reasoning in one assessment.

The Test of Everyday Reasoning (TER) provides objective assessment of the critical thinking skills of community college, GED, high school and adult test-takers. The TER is widely used by public and private high schools, prep schools, community colleges, technical colleges, businesses, government agencies and American and European International Schools  The TER-N is an enhanced version of the TER, measuring quantitative reasoning in addition to critical thinking skills.  

The TER-Numeracy brings all the skills analysis of the TER plus the added value assessing numeracy.

Children, adolescents and adults alike need to be able to think critically about the mathematical and numerical information that surrounds them in the media, on the Internet, in schools and workplaces, and in society at large. Dr. Carol Gittens, Director, University Office of Assessment, Santa Clara University, points out that “leading scholars and educators have consistently argued that numeracy rivals reading literacy and language fluency in its importance for learning and for life.”

Measuring Critical Thinking and Numeracy

Numeracy is the ability to solve quantitative reasoning problems and to make well-reasoned judgments derived from quantitative information in a variety of contexts. More than being able to compute or calculate a solution to a mathematical equation, numeracy includes understanding how quantitative information is gathered, represented, and correctly interpreted using graphs, charts, tables and diagrams.

The 40 question TER-N is available on our secure, encrypted online testing system. Scale scores reported include: Analysis, Interpretation, Inference, Evaluation, Explanation, Induction, Deduction and Reasoning Skills Overall plus Numeracy.

The TER-N enables our clients to objectively measure students’ mathematic reasoning skills and students’ critical thinking skills online in with a single instrument. Contact us to learn more.

Engaging problems and making decisions using critical thinking involves both skills and habits of mind. For a complete assessment of a test taker's critical thinking, it is recommended that both skills and dispositions be assessed. Using companion assessment measures results in a comprehensive measurement of whether a test taker is ‘willing and able’ to think well.

The recommended companion assessments for the TER include the California Critical Thinking Disposition Inventory (CCTDI) or the CM3 Level III.  Our client relations specialists will help you determine the optimal disposition tool for your objectives.

Scales Measured by the TER-Numeracy

Test of Everyday Reasoning - Numeracy, Grades 9+

The Test of Everyday Reasoning-Numeracy returns scores on these scales: Analysis, Evaluation, Inference, Deduction, Induction, Overall Reasoning Skills and Numeracy.

Scale Descriptions 



Numeracy skills are used when applying knowledge of numbers, arithmetic, measures, and mathematical techniques to situations that require the interpretation or evaluation of information.  Numeracy refers to the ability to solve quantitative reasoning problems, or make judgments derived from quantitative reasoning in a variety of contexts.  More than being able to compute a solution to a mathematical equation, numeracy includes the understanding of how quantitative information is gathered, manipulated and represented visually, such as in graphs, charts, tables and diagrams.



The reasoning OVERALL  Score describes overall strength in using reasoning to form reflective judgments about what to believe or what to do. To score well overall, the test-taker must excel in the sustained, focused and integrated application of core reasoning skills including analysis, interpretation, inference, evaluation, explanation, induction and deduction. The OVERALL score predicts the capacity for success in educational or workplace settings which demand reasoned decision making and thoughtful problem solving.


Analytical reasoning skills enable people to identify assumptions, reasons and claims, and to examine how they interact in the formation of arguments.  We use analysis to gather information from charts, graphs, diagrams, spoken language and documents.  People with strong analytical skills attend to patterns and to details. They identify the elements of a situation and determine how those parts interact.  Strong interpretation skills can support high quality analysis by providing insights into the significance of what a person is saying or what something means.


Interpretative skills are used to determine the precise meaning and significance of a message or signal, whether it is a gesture, sign, set of data, written or spoken words, diagram, icon, chart or graph. Correct interpretation depends on understanding the message in its context and in terms of who sent it, and for what purpose.  Interpretation includes clarifying what something or someone means, grouping or categorizing information, and determining the significance of a message. 


Evaluative reasoning skills enable us to assess the credibility of sources of information and the claims they make.  We use these skills to determine the strength or weakness of arguments.  Applying evaluation skills we can judge the quality of analyses, interpretations, explanations, inferences, options, opinions, beliefs, ideas, proposals, and decisions.  Strong explanation skills can support high-quality evaluation by providing the evidence, reasons, methods, criteria, or assumptions behind the claims made and the conclusions reached.  


Inference skills enable us to draw conclusions from reasons and evidence. We use inference when we offer thoughtful suggestions and hypotheses.   Inference skills indicate the necessary or the very probable consequences of a given set of facts and conditions.  Conclusions, hypotheses, recommendations or decisions that are based on faulty analyses, misinformation, bad data or biased evaluations can turn out to be mistaken, even if they have been reached using excellent inference skills.


Explanatory reasoning skills, when exercised prior to making a final decision about what to believe or what to do, enable us to describe the evidence, reasons, methods, assumptions, standards or rationale for those decisions, opinions, beliefs and conclusions.  Strong explanatory skills enable people to discover, to test and to articulate the reasons for beliefs, events, actions and decisions.  


Decision making in contexts of uncertainty relies on inductive reasoning. We use inductive reasoning skills when we draw inferences about what we think is probably true based on analogies, case studies, prior experience, statistical analyses, simulations, hypotheticals, and patterns recognized in familiar objects, events, experiences and behaviors. As long as there is the possibility, however remote, that a highly probable conclusion might be mistaken even though the evidence at hand is unchanged, the reasoning is inductive. Although it does not yield certainty, inductive reasoning can provide a confident basis for solid belief in our conclusions and a reasonable basis for action.


Decision making in precisely defined contexts where rules, operating conditions, core beliefs, values, policies, principles, procedures and terminology completely determine the outcome depends on strong deductive reasoning skills. Deductive reasoning moves with exacting precision from the assumed truth of a set of beliefs to a conclusion which cannot be false if those beliefs are true. Deductive validity is rigorously logical and clear-cut.  Deductive validity leaves no room for uncertainty, unless one alters the meanings of words or the grammar of the language. 

Comparison Percentiles Available for the TER

Test of Everyday Reasoning - Numeracy, Grades 9+

Individual and group scores are provided for all Insight Assessment test takers. Different groups of test takers have very different performance levels and therefore their scores differ quite a bit on scientifically developed measures of cognitive ability. It is important to understand how your group of test takers compares to selected external comparison groups, for example, the population of comparable regional or national peer groups.

The reports for each Insight Assessment test instrument provide scores that can be benchmarked against a variety of external comparison groups so that our clients are able to evaluate the scores of individual test takers or of their entire group.  If you do not see what you are specifically looking for, contact us to discuss your needs with a testing specialist.
