Campaigners have warned that the British government is not doing enough to prevent left-handed pupils from falling behind their peers. They claim that thousands of children are still being “penalized” for being left-handed. This is due to a lack of action from ministers, who’ve failed to take any meaningful action for years.
It is feared that a failure to address early-year challenges, such as poor handwriting, leads to much more serious problems down the line—with these pupils facing reduced career prospects.
Studies in recent years show that left-handed children are more likely to suffer with learning difficulties and their scores are lower on IQ tests.
Campaigners feel it’s strange that children in British schools are penalized because they happen to be left-handed. They don’t understand why successive governments have failed to act on this. They want the department of education to record which children are left-handed and what their educational attainments are, since they make up some 10% of the population.
In early-year education, left-handed children are struggling and making a mess of their handwriting. Educators don’t know how to deal with this.
In many cases, there is no active help and a lack of teacher training. Campaigners point out that a high percentage of the prison population is left-handed. They say that these prison numbers are unusually high and ask why it is the case.
