Working-class children are no more likely to move up the social ladder and hold a middle-class job if they attend a grammar school, rather than a comprehensive, a study has found.

The report keeps changing the objects of comparison......
........... Attending a grammar school did improve a working-class child's chance of earning slightly more than their parents. But children from middle-class homes, who went to grammar schools, also earned slightly more than their parents had done.
However, across the sample, the advantages of going to a grammar school were cancelled out by the social disadvantages experienced by those who went to secondary moderns. These adults did not have a different social class or earning power to their fathers.
[so the report is saying that those that went to Grammar School, whether from working class or middle class, earned more than their parents, as opposed to those that went to secondary moderns who did not]
Her co-author, Adam Swift, a politics lecturer at Oxford, said that grammar schools "confer no more advantage" to working-class children than to those from slightly more wealthy backgrounds.
[so he is saying you do get an advantage but no more than to those from slightly more wealthy backgrounds]
Not sure what this 'proves' tbh........
