California Critical Thinking Skills Test
CCTST prep: understand the exam before you sit for it
The CCTST does not test what you know. It tests how you reason, across seven core skills, in questions that contain everything you need to answer them. That makes it feel unfamiliar to students who prepared for content exams, and it makes targeted practice the most effective way to get ready. This page explains how the exam works, what it scores, and how to prepare.
Dedicated CCTST practice is in development at StudyBuddy, built by the team behind the most complete HSRT prep course, its sibling exam from the same publisher. Join the early access list below.
What the CCTST measures
The CCTST is published by Insight Assessment and built on the Facione model of critical thinking, the same framework behind the HSRT. The college-level version is typically 34 multiple-choice questions in about 45 minutes. Items use everyday and academic scenarios, and no subject knowledge is required or rewarded. Your report includes an overall score plus scale scores across the core reasoning skills:
Analysis
Identifying what an argument claims, what supports it, and the assumptions it depends on.
Interpretation
Reading exactly what a statement says, including qualifiers, conditions, and ambiguity.
Inference
Drawing only the conclusion the evidence actually supports, and recognizing when none is forced.
Evaluation
Judging the credibility of claims and the strength of the reasoning behind them.
Explanation
Stating results accurately and justifying how a conclusion was reached.
Induction
Reasoning well in uncertain, probabilistic, real-world situations.
Deduction
Reasoning well in precisely defined, rule-governed situations where conclusions follow with certainty.
Who takes the CCTST
Colleges and universities use the CCTST for program admissions, advising, learning outcomes assessment, and accreditation. Some institutions require it of applicants to competitive programs. Others administer it to all students as a graduation assessment. Requirements and score expectations vary by institution, so always confirm the details with your program: which version you will take, whether a minimum score applies, and how the result is used.

How to prepare for the CCTST
Reviewing biology, math, or vocabulary will not move your CCTST score, because the exam does not test content. What works is practicing the reasoning patterns the exam uses: reading statements precisely, separating conclusions from premises, judging whether evidence actually supports a claim, and noticing when a conclusion goes further than the facts allow. These are trainable skills, and they improve fastest when you practice realistic questions and study written explanations of why each answer is right and why the tempting ones fail.
If your exam is soon and you want structured reasoning practice now, our HSRT course trains the same skill set. The HSRT is the health sciences member of the CCTST family, and its reasoning modules cover analysis, inference, evaluation, induction, and deduction, the same skills your CCTST report will score.
Frequently asked questions
What is the CCTST?
The California Critical Thinking Skills Test (CCTST) is a standardized reasoning exam from Insight Assessment. It measures core critical thinking skills such as analysis, interpretation, inference, evaluation, explanation, induction, and deduction. The college-level version is typically a 34-question multiple-choice test taken in about 45 minutes. It does not test subject knowledge. Every question contains all the information needed to answer it.
Is the CCTST the same as the HSRT?
They are siblings. The Health Sciences Reasoning Test (HSRT) is the member of the CCTST family designed for health sciences students, published by the same company (Insight Assessment). Both exams score the same core reasoning skills. The main difference is the scenario dressing: HSRT items use health-adjacent contexts, while CCTST items use everyday and academic contexts. The reasoning being tested is the same.
How is the CCTST scored, and what is a good score?
The CCTST reports an overall score plus scale scores for individual reasoning skills, benchmarked against percentile comparison groups. There is no universal passing score. Each program or institution sets its own expectations, so always confirm the requirement with the program you are applying to.
Can you study for the CCTST?
Yes, but not by memorizing content. The CCTST measures reasoning skills, and those skills improve with deliberate practice: interpreting statements precisely, taking arguments apart, judging evidence, and drawing only the conclusions the facts support. Practicing realistic questions in each skill area, with explanations of why answers are right or wrong, is the most direct preparation.
Does StudyBuddy have a CCTST course?
A dedicated CCTST course is in development. StudyBuddy currently offers the most complete preparation course available for the HSRT, the health sciences member of the same exam family, training the same reasoning skills.
