New research done by King's College, London has revealed that teacher assessments are helpful in predicting the exam scores of students.
The study done across the age group of 7-14 revealed that teacher assessments were correlated with examination scores. It was found to be reliable, heritable and stable as examination scores throughout the schooling period. Genetic correlation was ~.80,and phenotypically (r~.70).
The study shows that teacher assessments could put emphasis away from high-stakes examinations and can be used as a guide to monitory the abilities, inclinations and progress of students. High-stake exams have an impact on teacher's morale and increased testing in schools have caused mental health problems in children in UK.
