Study: Kids who eat regular breakfast score better
GCSE grades converted to score points
GCSE grades were converted to point scores using the Department for Education's 2012 system, where A* = 58, A = 52, B = 46, and so on.
Adding up students' scores across all subjects gave students an aggregated score. Those who rarely ate breakfast scored on average 10.25 points lower than those who frequently ate breakfast, a difference of nearly two grades, after accounting for other important factors including socio-economic status, ethnicity, age, sex and BMI. Looking at performance for each individual GCSE, they found that students who rarely ate breakfast scored on average 1.20 points lower than those who frequently ate breakfast, after accounting for other factors. Each grade equates to six points, so the difference accounted for a drop of a fifth of a grade for every GCSE an individual achieved, the study said.
