There are three main components of the Pupil Achievement Tracker:

->  pupil target setting,

This provides a facility  by which schools can set targets informed by the progress made by similar pupils nationally

->  question level analysis

This provides information about what pupils can achieve in National Curriculum and Optional Tests from Years 2 through to 9. 

->  analysis of value-added data

This is applied to different cohorts within the school
