Cambridge International prepares school students for life, helping them develop an informed curiosity and a lasting
passion for learning. We are part of the University of Cambridge.
Our Cambridge Pathway gives students a clear path for educational success from age 5 to 19. Schools can shape
the curriculum around how they want students to learn – with a wide range of subjects and flexible ways to offer
them. It helps students discover new abilities and a wider world, and gives them the skills they need for life, so they
can achieve at school, university and work.
Our programmes and qualifications set the global standard for international education. They are created by subject
experts, rooted in academic rigour and reflect the latest educational research. They provide a strong platform for
students to progress from one stage to the next, and are well supported by teaching and learning resources.
We review all our syllabuses regularly, so they reflect the latest research evidence and professional teaching
practice – and take account of the different national contexts in which they are taught.
We consult with teachers to help us design each syllabus around the needs of their learners. Consulting with
leading universities has helped us make sure our syllabuses encourage students to master the key concepts in the
subject and develop the skills necessary for success in higher education.
Our mission is to provide educational benefit through provision of international programmes and qualifications for
school education and to be the world leader in this field. Together with schools, we develop Cambridge learners
who are confident, responsible, reflective, innovative and engaged – equipped for success in the modern world.
Every year, nearly a million Cambridge students from 10 000 schools in 160 countries prepare for their future with
the Cambridge Pathway.
Quality management
Cambridge International is committed to providing exceptional quality. In line with this commitment, our
quality management system for the provision of international qualifications and education programmes for
students aged 5 to 19 is independently certified as meeting the internationally recognised standard,
ISO 9001:2015. Learn more at www.cambridgeinternational.org/ISO9001
Key benefits
The best motivation for a student is a real passion for the subject
they’re learning. By offering students a variety of Cambridge
International AS & A Levels, you can give them the greatest chance
of finding the path of education they most want to follow. With
over 50 subjects to choose from, students can select the ones
they love and that they’re best at, which helps motivate them
throughout their studies.
Cambridge International AS & A Level Thinking Skills develops a set of transferable skills. These include
critical thinking, reasoning and problem solving. Learners can apply these skills across a wide range of subjects
and complex real world issues. These transferable skills equip students well for progression to higher education
or directly into employment.
Our approach in Cambridge International AS & A Level Thinking Skills encourages learners to be:
responsible, independently evaluating arguments and possible solutions to problems, and justifying their reasoning
reflective, carefully considering various possible perspectives of an argument, and the diverse ways that a problem
may be solved
innovative, formulating further arguments based on unfamiliar source materials and devising problem-solving
strategies
engaged, using strategies and techniques for managing unfamiliar information and contextualised problems.
‘Cambridge students develop a deep understanding of subjects and independent thinking skills.’
Tony Hines, Principal, Rockledge High School, USA
UK NARIC, the national agency in the UK for the recognition and comparison of international qualifications and
skills, has carried out an independent benchmarking study of Cambridge International AS & A Level and found it to
be comparable to the standard of AS & A Level in the UK. This means students can be confident that their Cambridge
International AS & A Level qualifications are accepted as equivalent, grade for grade, to UK AS & A Levels by leading
universities worldwide.
Cambridge International AS Level Thinking Skills makes up the first half of the Cambridge International A Level
course in Thinking Skills and provides a foundation for the study of Thinking Skills at Cambridge International
A Level.
Cambridge International AS & A Level Thinking Skills helps to provide transferable skills which support further
subject specific study. It is suitable for candidates intending to enter employment or further study, or as a part of a
course of general education.
For more information about the relationship between the Cambridge International AS Level and Cambridge
International A Level see the ‘Assessment overview’ section of the Syllabus overview.
We recommend learners check the Cambridge recognition database and university websites to find the most
up-to-date entry requirements for courses they wish to study.

2 Syllabus overview
Aims
The aims describe the purposes of a course based on this syllabus.
‘Cambridge International AS & A Levels prepare students well for university because they’ve
learnt to go into a subject in considerable depth. There’s that ability to really understand the
depth and richness and the detail of a subject. It’s a wonderful preparation for what they are
going to face at university.’
US Higher Education Advisory Council
Content overview
The Thinking Skills subject content is divided into two parts, Problem Solving and Critical Thinking. The subject
content is the same for AS & A Level. The difference between AS Level and A Level is determined by the demand of
the assessment tasks.
Problem Solving
The Problem Solving content is presented in four areas:
• Organise information
• Process information
• Analyse data
• Consider wider problems.
Problem Solving is about making use of the information available to deduce further information, draw conclusions
and make choices and decisions. Very often problems will involve numerical information, but problem solving is
not a test of mathematics. Only basic numeracy is expected, although these numeracy skills are a vital part of
the toolkit for solving many problems. Confidence in working with numerical information and performing mental
arithmetic is therefore important for developing efficient problem-solving skills, but the focus of the syllabus is to
develop the problem-solving skills themselves.
Students are expected to have basic numeracy skills, including understanding of percentages, ratio and proportion.
They should also understand the simple statistical measures of mean, median and mode, and be able to represent
the chances of something happening in precise numerical terms (i.e. as a fraction, decimal or percentage). Simple
algebraic skills can be a very powerful tool for problem solving, particularly for more complex problems. These
skills include the ability to represent and manipulate information, and relationships between pieces of information,
concisely and efficiently. However, these algebraic skills will never be assessed directly; the focus of the syllabus is
on developing the student’s ability to make valid problem-solving insights and deductions, whether they make use
of these tools or not.
Critical Thinking
The Critical Thinking content is presented in four areas:
• Evaluate and use evidence
• Analyse reasoning
• Evaluate reasoning
• Construct reasoning.
Critical Thinking is about judging the value or usefulness of evidence, and understanding how sound arguments are
constructed. Students will encounter a broad variety of topics, often reflecting real-world situations or subjects
of debate. Although a student’s own thinking about a topic sometimes makes a valuable contribution to their
critical thinking – for example, when constructing an argument – knowledge of the topics themselves will never be
assessed directly.
As in the real world, some topics may be controversial, and students may have pre-existing feelings about them.
However, the focus of the syllabus is on the student’s ability to demonstrate the critical thinking skills, and not on
whether one point of view is morally superior to another. Students should develop the skills to accurately judge
evidence and argument by the relevant criteria, draw logical conclusions and suggest plausible explanations, and
construct persuasive arguments with clear structure that make valid use of the evidence available.

3 Subject content
This syllabus gives you the flexibility to design a course that will interest, challenge and engage your learners.
Where appropriate you are responsible for selecting resources and examples to support your learners’ study. These
should be appropriate for the learners’ age, cultural background and learning context as well as complying with
your school policies and local legal requirements.
Candidates for both AS Level and A Level should study all the Problem Solving and Critical Thinking subject
content.
Problem Solving
Candidates are expected to use these skills in Paper 1 Problem Solving and Paper 3 Problem Analysis and Solution.
1 Organise information
1.1 Understand information in the various forms in which it is presented
Candidates should be able to:
• Understand information presented as text, tables
and diagrams
• Extract the information that is relevant to the
problem to be solved
• Extract data from related data sets that can be
combined in the solution of a problem
2 Process information
2.1 Perform appropriate operations with information
Candidates should be able to: Guidance
• Use one or more items of information The operations may involve performing some
appropriately to solve a given problem calculations. The operations to be performed may be
obvious, such as when calculating the total price of a
basket of shopping from the individual prices, or may
need to be deduced, such as when working out the
amount of time that needs to be allowed for a set of
events to take place.
• Apply a model to a given situation Models may take a variety of forms, including
calculations to be made based on a set of input data
and simulations of events taking place over a period
of time.
3 Analyse data
3.1 Transform data
Candidates should be able to: Guidance
• Recognise alternative representations of a set of Identify equivalent representations of data such as
information a pie chart that represents the same data as a bar
chart.
Identify relationships between features of an object,
such as identical shapes in opposite corners of a tile
so that copies of the same object can be identified
after rotations or other transformations.
• Identify features of a model based on different For example, from a graph representing a model,
types of representation interpret the gradient appropriately in the context of
the model.
Critical Thinking
Candidates are expected to use these skills in Paper 2 Critical Thinking and Paper 4 Applied Reasoning.
6 Analyse reasoning
6.1 Analyse the structure of arguments
Candidates should be able to: Guidance
• Recognise an argument An argument as distinct from an explanation,
information, opinion.
• Identify key elements of an argument and explain Key elements:
their function – main conclusion
– intermediate conclusion
– reason
– counter-assertion
– counter-argument
– example
– evidence.
• Identify unstated assumption in an argument A step in the reasoning which is required in order
for the conclusion to be validly drawn, but is
not stated explicitly. Authors sometimes make
such assumptions when they consider part of the
support for their conclusion to be obvious, trivial or
uncontroversial. Alternatively, they may not realise
that there is a gap in their reasoning, or they may
be trying to conceal a significant weakness in the
reasoning by failing to make it explicit.
7 Evaluate reasoning
7.1 Identify flaws in reasoning and assess their impact on the strength of the reasoning
Candidates should be able to recognise and assess Guidance
the impact of:
• Equivocation Concealing a step in reasoning by tacitly shifting from
one meaning of a word or expression to another.
• Conflation Concealing a step in reasoning by treating two words
or expressions as if they were interchangeable even
though their meanings are different.
• Circular argument Relying on a claim in order to prove it.
• Begging the question Focusing an argument on an uncontroversial aspect
of an issue while stipulating or assuming the key
point.
• Invalid deduction Affirming the consequent or denying the antecedent.
• Causal flaw Claiming that just because one event or phenomenon
follows another (post hoc) or is accompanied by
another (cum hoc) it must be caused by the other.
• Rash generalisation Basing a generalisation on inadequate evidence.
• Sweeping generalisation Not allowing for exceptions to a generalisation.
• Restriction of options (false dichotomy) Denying the possibility of moderate opinions or
actions in order to claim that anyone who rejects one
extreme must accept its opposite.
• Confusion of necessary and sufficient conditions Interpreting a necessary condition as if it were
sufficient or a sufficient condition as if it were
necessary.
• Slippery slope argument Opposing an apparently moderate proposal by
alleging that it will inevitably lead to disastrous
consequences.
• Personal attack (ad hominem) Criticising opponents personally instead of
responding to their arguments.
• Counter-attack (tu quoque) Rejecting criticisms on the grounds that opponents
or other people are guilty of the same or equally
objectionable conduct.
• Straw man argument Misrepresenting opponents’ arguments in order to
respond to them more easily.
Note: Candidates are not required to know the Latin
technical terms included here, but they are likely to
encounter them in textbooks and other sources.
7.2 Identify weaknesses in reasoning and assess their impact on the strength of reasoning
Candidates should be able to recognise and assess Guidance
the impact of:
• Support It is a weakness if reasoning supports only part of the
conclusion which is drawn from it. It is a weakness if a
moderate claim or intermediate conclusion is used to
support a conclusion which would follow only from a
stronger version of the claim.
• Consistency It is a weakness if one part of the reasoning
contradicts, or is inconsistent with, another part.
• Reliance The fact that a reader (e.g. a candidate) disagrees
with a claim or a conclusion does not constitute
a weakness in reasoning. However, reliance on an
unsupported claim, stipulative definition or unstated
assumption which is questionable does constitute a
weakness, because it means that anyone who rejects
the claim, definition or assumption can reasonably
also reject the conclusion.
• Appeal Arguments frequently make appeals, e.g. to
authority, popularity, emotion, tradition or novelty.
If such an appeal is relevant and proportionate, it
does not constitute a weakness in reasoning. But an
appeal which is irrelevant or disproportionate does
constitute a weakness in reasoning.
• Analogy Arguments often make use of analogies. Even
imperfect analogies can strengthen an argument,
but a wild analogy which lacks significant points of
similarity constitutes a weakness in reasoning.
• Responding to counter It is not a weakness for an argument to be one-sided.
Someone defending one point of view is under no
obligation to show balance. But it is a weakness if the
proponent fails to foresee and respond to an obvious
objection to a claim or line of reasoning.
8 Construct reasoning
8.1 Construct persuasive arguments
Candidates should be able to: Guidance
• Articulate a conclusion
• Provide reasons in support of a conclusion
• Develop strands of reasoning
• Structure reasoning by the use of intermediate
conclusions
• Strengthen reasoning by the use of appropriate Appropriate elements:
elements – counter-assertion/argument with response
– example
– evidence
– analogy
– hypothetical reasoning.
Calculators
Calculators are allowed in all the papers. They are essential for Paper 3 and useful for Paper 1.
Language
Much of Thinking Skills involves considering logical relationships and implications. In Problem Solving, candidates
need to accurately identify the constraints and requirements of the logical ‘space’ the problem is set in. In Critical
Thinking, candidates need to judge whether a claim does or does not follow from the evidence, and whether a chain
of reasoning does or does not support a conclusion.
An important focus of the syllabus is to prepare candidates to apply their thinking skills to many different aspects
of study, work and life. Therefore the stimulus material will often reflect what they will encounter in the real world,
where the language used is not always simple. The language used will aim not to be more complicated than is
necessary in key parts of the information.
Because of these key features of the subject, candidates will need to have a relatively strong grasp of English in
order to apply their thinking skills to scenarios in an English language medium.
Stimulus Material
The papers will contain stimulus material from a variety of sources, representing a variety of perspectives.
Any opinions expressed within such material are not necessarily those of Cambridge Assessment International
Education.
In Paper 1, the information presented in each scenario is usually quite limited. The Problem Solving skills are tested
more often in isolation than on Paper 3. The problems are shorter, less complex and less difficult.
There will be a variety of Problem Solving scenarios testing various skills. Some will be simple scenarios with just
one question. Others may involve two or more part-questions, exploring different aspects of a scenario or breaking
a more complex problem down into smaller steps. The problems will generally increase in difficulty through the
paper.
Credit will often be awarded for correct steps towards a solution, even if the final answer is not correct. Credit
might not be awarded if working or an explanation needed to support an answer is not shown (for example, where
the answer is either ‘Yes’ or ‘No’). Candidates should ensure that they lay their working out clearly, so that the
elements of their working can be easily identified. This will help them both to organise information and so solve
the problems more efficiently and successfully, and to gain the full credit they deserve for their Problem Solving
attainment.
In Paper 2, the Critical Thinking skills are tested more often in isolation than on Paper 4. The tasks are shorter
and more targeted at particular skills or pieces of evidence. It is generally easier to apply the skills to the stimulus
material.
Section A focuses mostly on evaluating and using evidence. There are several Sources of evidence based around a
common topic. The information is usually mostly in textual form, but there may also be other forms such as graphs,
diagrams, tables, pictures or numerical information. Question 1 has a number of short part-questions exploring
various aspects of the evidence presented in the sources. Question 2 requires the candidates to write a short
argument, with a focus on using and evaluating the evidence from the Sources.
Section B focuses mostly on reasoning and argument. There will be a passage of around 400 words, presenting
an argument. Question 3 will usually focus on analysing the structure of the reasoning in the argument, while
Question 4 will usually focus on evaluating the strength of the reasoning. Each will have a number of short
part-questions. Question 5 will require the candidates to write a short argument, in which the focus will be on
structuring the reasoning.
In Paper 3, the information presented in each scenario is often more detailed. The Problem Solving skills are tested
more often in combination than on Paper 1. The problems are longer, more complex and more difficult.
There are four questions presenting more extensive problems to be solved. A variety of skills are tested in each
question, and skills often need to be combined to find solutions. Often the problems develop towards a more
refined solution, such that the insights gained in the earlier parts are built upon and combined to provide solutions
to the later parts. The problems generally increase in difficulty through the paper.
Credit will often be awarded for correct steps towards a solution, even if the final answer is not correct. Credit
might not be awarded if working or an explanation needed to support an answer is not shown (for example, where
the answer is either ‘Yes’ or ‘No’). Candidates should ensure that they lay their working out clearly, so that the
elements of their working can be easily identified. This will help them both to organise information and so solve
the problems more efficiently and successfully, and to gain the full credit they deserve for their Problem Solving
attainment.
In Paper 4, the Critical Thinking skills are tested more often in combination than on Paper 2. Some tasks are longer
and refer to a broader range of the stimulus material. It is generally more difficult to apply the skills to the stimulus
material.
The paper presents a number of Documents, usually five, containing information and arguments around a common
topic. The Documents are usually mostly in textual form, but there may also be other forms such as graphs,
diagrams, tables, pictures or numerical information.
Question 1 tests the candidates’ ability to analyse the structure of the reasoning in one of the Documents, while
Question 2 focuses on evaluating the strength of the reasoning in one of the Documents. Question 3 requires the
candidates to evaluate specific pieces of evidence (often statistical in nature) from the Documents. In Question 4,
candidates are required to construct a substantial reasoned argument. The question targets their ability to combine
their Critical Thinking skills in order to present a persuasive case. They must demonstrate the ability to structure
their arguments effectively and make critical use of the evidence from the Documents in support of their position.
Command words
The table below includes command words used in the assessment for this syllabus. The use of the command word
will relate to the subject context.
* In Paper 2 and Paper 4, ‘analyse’ requires candidates to identify key elements of an argument.

You can enter candidates in the June and November exam series.
Making entries
Exams officers are responsible for submitting entries to Cambridge International. We encourage them to work
closely with you to make sure they enter the right number of candidates for the right combination of syllabus
components. Entry option codes and instructions for submitting entries are in the Cambridge Guide to Making
Entries. Your exams officer has a copy of this guide.
Exam administration
To keep our exams secure, we produce question papers for different areas of the world, known as 'administrative
zones'. We allocate all Cambridge schools to one administrative zone determined by their location. Each zone has
a specific timetable. Some of our syllabuses offer candidates different assessment options. An entry option code
is used to identify the components the candidate will take relevant to the administrative zone and the available
assessment options.
Candidates can carry forward the result of their Cambridge International AS Level assessment from one series to
complete the Cambridge International A Level in a following series, subject to the rules and time limits described in
the Cambridge Handbook.
Regulations for carrying forward entries for staged assessment (Cambridge International AS & A Level) [and
internally assessed marks] can be found in the Cambridge Handbook for the relevant year of assessment at
www.cambridgeinternational.org/eoguide
The standard assessment arrangements may present barriers for candidates with impairments. Where a candidate
is eligible, we may be able to make arrangements to enable that candidate to access assessments and receive
recognition of their attainment. We do not agree access arrangements if they give candidates an unfair advantage
over others or if they compromise the standards being assessed.
Language
This syllabus and the related assessment materials are available in English only.
Grades a, b, c, d or e indicate the standard a candidate achieved at Cambridge International AS Level. ‘a’ is the
highest and ‘e’ is the lowest grade.
‘Ungraded’ means that the candidate’s performance did not meet the standard required for the lowest grade
(E or e). ‘Ungraded’ is reported on the statement of results but not on the certificate. In specific circumstances
your candidates may see one of the following letters on their statement of results:
• Q (PENDING)
• X (NO RESULT).
If a candidate takes a Cambridge International A Level and fails to achieve grade E or higher, a Cambridge
International AS Level grade will be awarded if both of the following apply:
• the components taken for the Cambridge International A Level by the candidate in that series included all the
components making up a Cambridge International AS Level
• the candidate’s performance on the AS Level components was sufficient to merit the award of a Cambridge
International AS Level grade.
‘Cambridge International A Levels are the ‘gold standard’ qualification. They are based on
rigorous, academic syllabuses that are accessible to students from a wide range of abilities yet
have the capacity to stretch our most able.’
