Children’s genes expose potential school league table bias

A new examination of the role of children's genomes in their education progress reveals their impact on both school league tables and how teacher performance is assessed.

A new study that identifies a role of children’s genes in their education progress suggests that during the secondary school, some of the value-added measures of progress, which account for factors like gender, age, and ethnicity of the students, were influenced by the differences in students’ genetics.

In addition, scientists found that differences in genetics can explain more of the value-added measures made by the teachers ‘assessment of their students’ ability.

It suggests, these measures partly reflect the understudies that schools and teacher’s intake instead of just the schools and teacher’ commitment to their understudies’ training.

A group driven by University of Bristol scientists utilized information from 6,518 members of the Children of the 90s longitudinal investigation close by the UK National Pupil Database of exam results. As individuals’ genes don’t change after some time, they needed to know whether esteem included advancement estimates just reflect school and teacher performance or additionally genetic contrasts between understudies.

Value-added statistics think about student intake and earlier capacity trying to give impartial markers of school and teacher performance. Since school class tables are built from these measurements, they are thought to be exact and give a reasonable impression of the performance of schools and educators. This examination features that value-added measures and the subsequent school class tables are one-sided and may unjustifiably punish a few schools.

University of Bristol’s MRC Integrative Epidemiology Unit Senior Research Associate Tim Morris said, “Incorporating genetic information could profoundly affect our understanding of education and offer new ways to investigate the effectiveness of the educational policy. These findings suggest that value-added progress measures should be used with caution as they may misattribute pre-existing differences in children’s ability to schools and teachers.”

“School league tables may over or understate the effectiveness of schools depending on their intake, and teachers may be unjustly penalized based on their luck of the draw regarding the class they are given. Thanks to the wealth of data available through the Children of the 90s study we were able to conduct this work. The next steps should be to look at how the genetic differences we observe may be expressed, for example through attitude to work or behavior.”

The study is published in the British Educational Research Journal.
