Objectives
This assessment is a summative assessment of work covered in Units 13 to 22.
This assessment is designed to assess the pupils’ mathematical understanding and not their reading
ability. It is also important that it is completed by individuals and not with the support of other
pupils as this would not uncover any difficulties a pupil may be having with particular concepts.
