"We saw a 13% uplift in our Lit results this year at grade 5. One reason was definitely the frequency we could produce and assess student essays on Olex."

Custom KS3 Assessment

Stop losing ground in Years 7 to 9

KS3 is the missing middle of English assessment. Schools have national data at the end of KS2 and again at GCSE - but Years 7 to 9 are often assessed through locally designed tasks, rubrics and mark schemes. Olex establishes pupil starting points quickly in Year 7 and uses custom rubrics to build a consistent picture of progress all the way through to KS4.
