One of the earliest—and most important—decisions you’ll make in the IB Diploma Programme is choosing which subjects to take at Higher Level (HL) and which to take at Standard Level (SL). On paper, the distinction looks simple. In practice, it shapes your workload, your exam experience, and how universities interpret your academic profile.
If you’re weighing your options, this guide breaks down the real differences between HL and SL, beyond the labels.
HL vs SL: The Big Picture
All IB students take six subjects:
- Three at Higher Level (HL)
- Three at Standard Level (SL)
Both levels are graded on the same 1–7 scale, and both contribute equally to your 45-point total. The difference isn’t about points—it’s about depth, pace, and expectations.
1. Depth of Content and Teaching Time
The most concrete difference between HL and SL is how much you study.
- HL subjects: approximately 240 teaching hours
- SL subjects: approximately 150 teaching hours
HL courses cover:
- The full SL core
- Additional HL-only topics
- Greater conceptual depth and complexity
SL courses focus on:
- Core concepts
- Foundational understanding
- Less technical detail
For example, in subjects like Economics, HL students handle more quantitative analysis and extended theory, while SL students focus on core models and concepts.
