					BTEC APPLIED SCIENCE FIRST CERTIFICATE

The Edexcel BTEC course is assessed purely through coursework assignments
the students complete mainly in class. Students study the same content as the
traditional GCSE course but it is studied in context. For example, students will
study new material and then look at how they are used in industry or everyday
life.

Units studied:

      Biological Systems
      Physical Processes
      Applications of chemistry

Each unit has equal weighting in the final award of the qualification. Each unit is
divided into several assignments that each with a deadline for completion.

Assessment:
Course assessment = 100% coursework

Each unit studied is divided into a series of assignments that cover the grading
criteria for that unit.

The assignment is set with clear deadlines for each task within the assignment.
Students are expected to meet these deadlines and manage their time effectively
to ensure they are met.

The assignments are marked internally by their class teacher who will then have
a feedback session with the student to inform them of their grade for the
assignment and possible areas for improvement.
Students are allowed to revisit and improve any assignment until the final
deadline (mid May of year 11).

A sample of work is sent to an external moderator in year 10 of the course as
part of the Edexcel National Standards Sampling and work is constantly internally
verified amongst the science department to ensure the rigour of the qualification.


Sample assignment briefs and student work can be found on the website and
you will see there is a variety of different media skills used to present each task,
ranging from filming and editing an advert to investigating the reactivity of
Halogens practically.
