CEM, Durham University
Pupils vary enormously
Teachers have the greatest impact
Schools are relevant
Authorities hardly vary at all
Proximate variables dominate
“The findings of the review by no means constitute a ringing endorsement of teachers’ assessment; there was evidence of low reliability and bias in teachers’ judgements”
Developed ability test (MidYIS/IQ/etc)
Attainment test (Std Grade/Highers)
Later success – degree, salary etc
No easy solutions Stakes exams?
