3. Comparing SL and HL in IBDP ESS

Unique Feature: One Standard Level Course

Unlike many other IBDP subjects, ESS is offered only at Standard Level (SL). This approach ensures accessibility to all students, regardless of their scientific background, while maintaining the rigor and depth required for the Diploma Programme.

What Makes ESS Unique as an SL Course?

4. Marking Scheme and Assessment Structure

Internal Assessment (IA)

The IA contributes 25% to the final grade. It involves a student-led investigation, focusing on an environmental issue of their choice. The IA encourages research, experimentation, and critical evaluation.

Assessment Criteria

• Criterion A (2 marks): Research question and context.
• Criterion B (6 marks): Methodology and data collection.
• Criterion C (6 marks): Data analysis and interpretation.
• Criterion D (6 marks): Evaluation and conclusion.
• Criterion E (4 marks): Communication and presentation.

External Assessments

1. Paper 1 (30%)
   • Case study-based questions testing application and analysis of environmental issues.
2. Paper 2 (45%)
   • Short-answer and extended-response questions covering all core topics.

Marking Scheme Insights

5. The Internal Assessment: Investigating Real-World Environmental Issues

The IA allows students to explore an environmental topic of interest, applying scientific and societal perspectives.

Tips for a High-Scoring IA
