Note:


The Authorised Assignment Brief (AAB) used for generating this
learner work is the same as the one provided by Pearson. Centres are
expected to get the AAB fully internally verified prior to being issued
to the learners.

The learner work generated is an exemplar of standard for a particular
Learning Aim(s) and grade(s), and NOT a response to the entire task
detailed in the Authorised Assignment Briefs. We therefore expect
centres to use this resource to exemplify how to structure a response
to a task. We also encourage centres to use this work to standardise
their Assessment teams and demonstrate to learners the level of work
expected to achieve the different targeted grades outcome.
