Understanding IB Computer Science (2027 Specification)

The 2027 IB CS curriculum spans four core topic areas across two papers plus an internal assessment. Paper 2 has two language versions — Python or Java — chosen at course start. Toggle between SL and HL below to see how marks, durations, and content differ.

📝

Paper 1

Written exam on core CS fundamentals, networks, databases, machine learning concepts, and the annual Case Study. Same four topic units for SL and HL — marks and duration differ.

Topics (SL & HL)

✓ A1 Computer fundamentals
✓ A2 Networks
✓ A3 Databases
✓ A4 Machine Learning
✓ Case Study
💻

Paper 2

Algorithmic problem-solving and programming. Available in two versions — Python or Java — chosen at course start.

Topics

✓ B1 Computational thinking
✓ B2 Programming

✓ B4 ADT (Abstract Data Types)
+ Additional HL-only question topics HL only
🛠

Internal Assessment

Self-selected programming project & documentation for a real client. 35 hours class time for both SL and HL; the grade weighting differs.

Criteria (SL & HL)

✓ Criterion A: Problem definition & client needs
✓ Criterion B: System design & test planning
✓ Criterion C: Development & implementation
✓ Criterion D & E: Testing, demo & evaluation
