Overview of the AQA Science GCSE Specification
Purpose and Goals
The primary aim of the AQA Science GCSE specification is to foster a deep understanding of scientific principles and their relevance to everyday life. It encourages students to develop critical thinking, problem-solving skills, and scientific literacy necessary for informed decision-making and active participation in society.
The specification is designed to:
- Cover the fundamental concepts of biology, chemistry, and physics.
- Promote practical skills through laboratory work and investigations.
- Prepare students for further scientific study or careers.
- Encourage scientific curiosity and awareness of scientific issues in society.
Structure of the Specification
The AQA Science GCSE is typically divided into two main routes:
- Combined Science Trilogy (grades 9-1): Covering all three sciences in a combined course, resulting in two GCSE grades.
- Separate Sciences (Biology, Chemistry, Physics): Offering individual GCSEs in each science, suitable for students with a strong interest or aptitude in science.
Both routes include core content, practical assessments, and require students to demonstrate scientific understanding through written examinations.

Practical Skills and Investigations
Practical Work Requirements
Practical skills are integral to the AQA Science GCSE, ensuring students can:
- Plan and carry out experiments safely.
- Collect and interpret data accurately.
- Evaluate experimental methods and results.
- Develop scientific reasoning through practical investigations.
The specification mandates a minimum number of required practicals in each science, although schools are encouraged to undertake additional investigations to deepen understanding.
Assessment of Practical Skills
Practical skills are assessed indirectly through written exams, where students answer questions based on their practical experiences. They might analyze data from experiments, suggest improvements, or interpret results, demonstrating their understanding of scientific methods.

Assessment Structure and Methods
Examinations
The AQA Science GCSE assessments are primarily examination-based, with the following structure:
- Combined Science Trilogy: Two exam papers per science, each lasting approximately 1 hour 15 minutes, totaling four papers.
- Separate Sciences: Each science has its own set of exams, typically three papers per subject focusing on different content areas.
All exams include a mix of question types:
- Multiple choice.
- Short answer questions.
- Extended response questions requiring explanation and analysis.
Grading System
The grading system for AQA GCSEs transitioned from letters (A-G) to numbers (9-1), with 9 being the highest. The specification aims for a broad distribution of grades, encouraging high achievement while maintaining rigorous standards.
Additional Assessments
Some specifications include practical assessments or coursework, but in the AQA Science GCSE, practical competence is assessed mainly through exam questions, streamlining assessment processes.
