The California Critical Thinking Disposition Inventory is the premier tool for surveying the dispositional aspects of critical thinking. The CCTDI is specifically designed to measure the disposition to engage problems and make decisions using critical thinking. One must be disposed to think critically as well as have the skills to do so. The CCTDI is designed for use with the general adult population.

CCTDI Purpose

The CCTDI measures the “willing” dimension in the expression “willing and able” to think critically. High scores on the California Critical Thinking Disposition Inventory are positively correlated with a strong desire to apply one’s critical thinking skills in decision making and problem solving, with leadership, with ego resilience, and with the capacity to benefit from educational training and psychological counseling.

  • The CCTDI is based on the expert consensus characterization of the “ideal critical thinker” articulated in the APA Delphi Report.
  • The CCTDI is calibrated for use with the general adult population including workers and working professionals at all levels and students in grades 10 and above, including undergraduates, technical and professional school students, and graduate students.
  • In English or one of its many authorized translations, the CCTDI has been used to gather information about job and program applicants, to inform academic advising and personnel training programs, and in projects such as learning outcomes assessment, program evaluation, accreditation self-studies and psychological research.

CCTDI Overview

The CCTDI invites respondents to indicate the degree to which they agree or disagree with statements expressing familiar opinions, beliefs, values, expectations and perceptions that relate to the reflective formation of reasoned judgments.

Items use no technical vocabulary or critical thinking jargon.  Initially developed and validated in a post-secondary school population, the CCTDI has subsequently been demonstrated to perform well in secondary school students, the general public, graduate students and working professionals in the United States and in more than 40 countries around the world.

The CCTDI is administered with a generous preset time limit of 30 minutes. Most test takers easily complete it in less than 20 minutes.

Scales Reported

The CCTDI measures seven  attributes that influence an individual’s capacity to learn and to effectively apply critical thinking skills: the disposition toward truth-seeking or bias, toward open-mindedness or intolerance, toward anticipating possible consequences or being heedless of them, toward proceeding in a systematic or unsystematic way, toward being confident in the powers of reasoning or mistrustful of thinking, toward being inquisitive or resistant to learning, and toward mature and nuanced judgment or toward rigid simplistic thinking.

Test Administration

Our app based assessment tools are easily administered 24/7 via our secure, encrypted, online, multi-lingual interface over a wide array of major platforms while offering a single simple interface to mobile, or non-mobile users. An in-app tutorial makes it simple to administer the assessment.

Recommended Companion Assessments

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 both skills and dispositions be measured. Using companion assessments results in a comprehensive measurement of whether a test taker is ‘willing and able’ to think well.

The CCTDI can be taken in conjunction with multiple Insight Assessment skills test instruments including the college level California Critical Thinking Skills Test (CCTST). Our client relations specialists will help you determine the optimal skills assessment for your objectives.

There are seven scales on the California Critical Thinking Disposition Inventory CCTDITruthseeking, Open-mindedness,  Analyticity, Systematicity, Confidence in Reasoning, Inquisitiveness and Maturity of Judgment.  Each scale score describes an aspect of the overall disposition toward using one’s critical thinking to form judgments about what to believe or what to do. People may be positively, ambivalently, or negatively disposed on each of seven aspects of the overall disposition toward critical thinking.


Truthseeking is the habit of always desiring the best possible understanding of any given situation; it is following reasons and evidence where ever they may lead, even if they lead one to question cherished beliefs. Truth-seekers ask hard, sometimes even frightening questions; they do not ignore relevant details; they strive not to let bias or preconception color their search for knowledge and truth. The opposite of truthseeking is bias which ignores good reasons and relevant evidence in order not to have to face difficult ideas.


Open-mindedness is the tendency to allow others to voice views with which one may not agree. Open-minded people act with tolerance toward the opinions of others, knowing that often we all hold beliefs which make sense only from our own perspectives. Open-mindedness, as used here, is important for harmony in a pluralistic and complex society where people approach issues from different religious, political, social, family, cultural, and personal backgrounds. The opposite of open-mindedness is intolerance.


Analyticity is the tendency to be alert to what happens next. This is the habit of striving to anticipate both the good and the bad potential consequences or outcomes of situations, choices, proposals, and plans. The opposite of analyticity is being heedless of consequences, not attending to what happens next when one makes choices or accepts ideas uncritically.


Systematicity is the tendency or habit of striving to approach problems in a disciplined, orderly, and systematic way. The habit of being disorganized is the opposite tendency. The person who is strong in systematicity may not know of a given approach, or may not be skilled at using a given strategy of problem solving, but that person has the desire and tendency to try to approach questions and issues in an organized and orderly way. 

Confidence in Reasoning

Confidence in reasoning is the habitual tendency to trust reflective thinking to solve problems and to make decisions. As with the other attributes measured here, confidence in reasoning applies to individuals and to groups.  A family, team, office, community, or society can be trustful of reasoned judgment as the means of solving problems and reaching goals. The opposite habit is mistrust of reasoning, often manifested as aversion to the use of careful reason and reflection when making decisions or deciding what to believe or do.


Inquisitiveness is intellectual curiosity. It is the tendency to want to know things, even if they are not immediately or obviously useful. It is being curious and eager to acquire new knowledge and to learn the explanations for things even when the applications of that new learning are not immediately apparent. The opposite of inquisitiveness is indifference.

Maturity of Judgment

Maturity of judgment is the habit of seeing the complexity of issues and yet striving to make timely decisions.  A person with maturity of judgment understands that multiple solutions may be acceptable while yet appreciating the need to reach closure at times even in the absence of complete knowledge. The opposite, cognitive immaturity, is imprudent, black-and-white thinking, failing to make timely decisions, stubbornly refusing to change when reasons and evidence would indicate one is mistaken, or revising opinions willy-nilly without good reason for doing so.

The CCTDI has been designed to deliver high quality objective metrics on the strengths and weaknesses of key aspects of thinking.

CCTDI reports deliver individual and group results in a presentation ready format.   Each report includes a wide range of statistical and demographic information about individuals and/or test-taker groups. Test-taker scores and group summaries are presented with interpretative analysis by Insight Assessment measurement scientists.

The CCTDI  measures and reports on an array of mental disciplines:  Truthseeking, Open-mindedness,  Analyticity, Systematicity, Confidence in Reasoning, Inquisitiveness and Maturity of Judgment.

Insight Assessment clients depend on the comprehensive data and analysis in a CCTDI report to provide the insights needed to achieve their assessment goals.  Clients are currently using individual data for professional development, student or in placement, hiring, advising, competency training. Group data is being used for new cohort assessment, outcomes assessment, demonstrating the quality of an educational or training program, demonstrating group proficiency, staff development, admissions and more.

Clients can customize their results package with additional analyses, graphics and interpretative text discussing your scores in relationship to your particular goals and objectives. For further information, see Insight Assessment Reports and Analytics.
