What is a BTEC National in Applied Science?

Any BTEC National is a practical, work-related course. Students learn by completing projects and assignments that are based on realistic workplace situations, activities and demands. Students focus on a particular subject area and develop a range of specialist skills and knowledge.

At the Loxford School we are offering two qualifications:

BTEC Level 3 National Extended Certificate in Applied Science (360 GLH) (One A Level)

BTEC Level 3 National Diploma in Applied Science (720 GLH) (Two A Level)

Exams

Externally-assessed unitsEach external assessment for a BTEC National is linked to a specific unit. All of the units developed for external assessment are of 90 or 120 GLH to allow learners to demonstrate breadth and depth of achievement. Each assessment is taken under specified conditions, then marked by Pearson and a grade awarded. The styles of external assessment used for qualifications in the Applied Science suite are: Examinations – all learners take the same assessment at the same time, normally with a written outcome. This is for unit 1 & 5 Set tasks – learners take the assessment during a defined window and demonstrateunderstanding through completion of a vocational task. This is for unit 3.Some external assessments include a period of preparation using set information. External assessments are available once or twice a year and learners can have only one resit attempt during the programme.
