BTEC Level 3 Extended Certificate in Applied Science

The BTEC Level 3 Extended Certificate is broadly equivalent to one A-Level. The course is designed for learners who are interested in learning about the science sector alongside other fields of study, with a view to progressing to a wide range of higher education courses, not necessarily in applied science. It may also offer apprenticeship or direct employment opportunities. This course serves to be taken as part of a programme of study that includes other appropriate BTEC Nationals or A Levels.


The requirements of the qualification will mean that learners develop the transferable and higher order skills which are valued by higher education providers and employers. For example, when studying Unit 3: Science
Investigation Skills, learners will develop skills including how to plan investigations, collecting, analysing, and presenting data and communicating results which support some of the skills learners need to progress to higher education, employment, self-employment or training.


The Qualification consists of three mandatory units:
  • Unit 1: Principles and Applications of Science I
  • Unit 2: Practical Scientific Procedures and Techniques
  • Unit 3: Science Investigation Skills
Learners will also study one optional unit from the following:
  • Unit 8: Physiology of Human Body Systems
  • Unit 10: Biological Molecules and Metabolic Pathways
  • Unit 13: Applications of Inorganic Chemistry
  • Unit 15: Electrical Circuits and their Application


Mandatory units; 1: Principles and Applications of Science I and Unit 3: Science Investigation Skills are externallyset written examination and written task assessments.

Mandatory Unit 2: Practical Scientific Procedures and Techniques and the designated optional unit are portfolio based assessments.


The minimum entry requirements for level 3 applied study apply. In addition, Grade 4 or above in GCSE Science (single or combined) or Merit in Level 2 BTEC Applied Science study and Grade 4 in Mathematics is required.
