RevisionDojoOverview of IB and A-Levels
Both the International Baccalaureate (IB) Diploma Programme and A-Levels are prestigious pre-university qualifications recognized worldwide. However, they differ in structure, assessment style, and educational philosophy.
- IB Diploma Programme: A two-year course with six subjects plus core components (Extended Essay, Theory of Knowledge, CAS). Emphasizes breadth and holistic development.
- A-Levels: Typically a two-year program focusing on 3-4 subjects in-depth, allowing specialization. Predominantly exam-based.
Curriculum Structure
IB Diploma
- 6 subjects across 6 groups (Languages, Sciences, Humanities, Math, Arts)
- 3 subjects at Higher Level (HL), 3 at Standard Level (SL)
- Core components: Extended Essay (EE), Theory of Knowledge (TOK), Creativity, Activity, Service (CAS)
- Emphasizes critical thinking, research skills, and global awareness
A-Levels
- Choose 3 or 4 subjects to study in-depth
- No compulsory core components
- Focus on specialization suited to intended university course
- Assessment primarily through final exams
Assessment Methods
- IB: Mix of internal assessments (projects, presentations, essays) and final exams; continuous assessment throughout two years.
- A-Levels: Mostly final exams at the end of two years; some subjects include coursework.
University Recognition
Both qualifications are widely accepted globally.
- IB is praised for preparing students with well-rounded skills, preferred by some universities for its rigorous holistic approach.
- A-Levels are valued for subject depth, especially in the UK and countries with British-influenced systems.
