The California Critical Thinking Skills Test is the premier critical thinking skills test in the world today. Called the "gold standard" of critical thinking tests, the CCTST is based on the Delphi Expert Consensus Definition of Critical Thinking.

Different questions progressively invite test-takers to analyze or to interpret information presented in text, charts, or images; to draw accurate and warranted inferences; to evaluate inferences and explain why they represent strong reasoning or weak reasoning; or to explain why a given evaluation of an inference is strong or weak. The 34 multiple choice test items range in difficulty and complexity.

The CCTST items broadly represent reasoning ability required to succeed in those educational and workplace settings skill in thoughtfully forming a judgment regarding what to believe or what to do is a prerequisite. The CCTST itself is recommended for use with college level and post-baccalaureate populations.
