Washington: Teacher assessments of pupils are powerful predictors of success and are as good as exams, claim researchers.
A study published in the ‘Journal of Child Psychology and Psychiatry’, questions whether the benefits of standardised exams outweigh the costs.
Teacher assessments found to correlate strongly with exam scores across English, mathematics and science from age 7-14, with both measures equally powerful at predicting exam success.
Teacher assessments predicted around 90 per cent of the differences between pupils in exam performance at General Certificate of Secondary Education (GCSE) and A-level, according to researchers at King’s College London.
Co-lead researcher Dr Kaili Rimfeld, said, “We have shown for the first time that teacher assessments predict GCSE and A-level results just as well as earlier exam scores. The fact that exam scores correlate so highly with the teacher assessments raises questions about the value of the testing culture that characterises compulsory education in the United Kingdom.”
“While testing can stimulate both pupils and teachers to focus their efforts, high-stakes exams may shift the educational experience away from learning towards exam performance. For these reasons, we suggest that teacher assessments could be relied on for monitoring progress, instead of exam scores, in particular during earlier school years,” said another Co-lead researcher Dr Margherita Malanchini.
Previous research has looked at how either exam scores or teacher assessments predict educational success, but not compared the two.
The researchers were able to make the comparison by linking data from over 5,000 twin pairs in the Twins Early Development Study(TEDS) with teacher assessments and exam scores in the National Pupil Database.
Previous research from King’s College London has established that genetic factors are the major influence on exam results for GCSEs and A-levels.
Using data from TEDS, the researchers showed a strong genetic correlation between teacher assessments and exam scores, confirming that both measures were identifying the same pupils and largely measuring the same ability.
Teachers in the UK are required to assess their pupils until age 14, and children sit standardised exams throughout school education in the UK.
“We are not arguing against testing in general, or that teacher should increase their workloads by adding further assessments. On the contrary, we have demonstrated that current methods of teacher assessment are powerful predictors of success, allowing schools to reduce testing and still monitor progress effectively,” said Dr Rimfeld.
“Our results should inform the debate about testing during both primary and secondary education. Trusting teachers to implement the curriculum and monitor progress could benefit the wellbeing of pupils and teachers and help to bring joy back to the classroom,” said Dr Malanchini.
Previous research has suggested high-stakes exams can impact teachers’ morale as well as pupils’ wellbeing and mental health. The researchers are now looking to study the links between school experiences and mental health among young people.
