IB Computer Science SL: connect theory with working code

Bring a recent question, your attempted solution and your school’s programming language. Lessons can start at the point where your explanation or program stops working.

Explain before memorising. Use a concrete example to explain a network, database or machine-learning concept, then practise a concise written answer.

Trace, run and test. Predict the output of a short Python or Java program, check it, and explain the first unexpected result. Include object-oriented programming in your SL practice.

Prepare your own assessment work. Bring case-study notes or your own IA idea and draft. Feedback helps you justify decisions and test your solution; the assessed work remains yours.

Choose the right IB Computer Science level

SL and HL share a common foundation, while HL adds deeper systems, data structures, and programming depth for students who need the higher-level route.

Who should take CS SL?

Computer Science SL works best when the student's university goals, mathematical confidence, and preferred problem style match the course route.

Students taking IB Computer Science at Standard Level who want a clear map of theory, programming and assessment.

Learners who need Python or Java practice connected to IB-style algorithms, tracing, testing and written explanations.

Students who want step-by-step IA guidance from problem choice to testing, evaluation and final documentation.

CS SL syllabus, organized for scoring

For first assessment in 2027, Theme A covers computer science fundamentals and Theme B covers computational thinking and problem-solving. Both levels include programming, object-oriented programming, machine learning, a case study and an independently developed IA.

01

Systems and Data

Computer organization, networks, data representation, databases, machine learning, security and the impact of technology in real contexts.

02

Computational Thinking

Algorithm design, abstraction, decomposition, pseudocode, trace tables, testing and evaluation.

03

Programming

Python or Java practice for control structures, functions, arrays/lists, strings, files, object-oriented programming, debugging and readable solutions.

04

Case Study

Guided reading, research vocabulary, concept maps and practice responses for the current case study style.

05

Internal Assessment

Support for choosing a realistic client problem, building the solution, collecting test evidence and writing the evaluation.

CS SL topic-wise syllabus

A practical, student-friendly map of what is taught inside each topic family.

01

SL Core

Build reliable foundations across theory, programming and computational thinking.

New Syllabus Habits

Prepare for a syllabus that rewards understanding, application and clear explanation.

CS SL Syllabus

Core topics taught for this route

Concept-first notes rather than memorised definitions Programming linked to exam-style problems Short written responses using correct technical terms Case study research connected to syllabus themes IA documentation built alongside development

Exam and IA preparation

1

Paper 1 theory preparation with definitions, diagrams, applied examples and concise written explanations.

2

Paper 2 algorithm and programming preparation using Python or Java, trace tables, debugging and problem decomposition.

3

Case study preparation through guided reading, vocabulary banks, research notes and timed response practice.

4

Internal Assessment support for solution planning, development, testing evidence, evaluation and final presentation.

Teaching plan

  • Start with a syllabus map and identify whether theory, programming or IA is the urgent gap.
  • Teach each concept with short notes, worked examples, exam questions and programming drills where relevant.
  • Keep a running case-study glossary and response bank so revision is not left until the end.
  • Build the IA in milestones: client problem, design, prototype, testing evidence, evaluation and final polish.

Common questions about CS SL

Clear answers for parents and students comparing the current syllabus with the older course structure.

01

Is this for the current new IB Computer Science syllabus?

Yes. The course is organized for the new IB DP Computer Science syllabus: first teaching August 2025 and first assessment May 2027. Students sitting final exams in 2026 may still be on the older syllabus.

02

What is different from the older syllabus?

For first assessment in 2027, option papers are removed and the case study is assessed in Paper 1 at both levels. OOP is included at SL and HL; abstract data types are HL-only. Students assessed in 2026 should use their earlier course guide.

03

Do SL students need strong coding before starting?

No. SL students can start with basic programming and build steadily, but they do need regular practice in tracing, debugging and explaining code.

04

Can the IA be done in Python?

Yes, if Python is appropriate for the student's problem and school requirements. The focus is a clear computational solution with testing, documentation and evaluation.

05

How is SL different from HL?

Both levels include computer fundamentals, networks, databases, machine learning, programming and OOP. HL extends the depth and includes abstract data types. Compare the level and assessment requirements with your school before choosing.

06

When should a student start IA planning?

Ideally early, once basic programming is stable. Starting early avoids rushed projects and gives time for testing evidence and meaningful evaluation.
