Charter schools rated just as effective as reducing class sizes

Now this is very interesting. The meta-meta study of 50,000 studies of 139 factors influencing education outcomes had class size at 106th with an effect score of 0.21. At 107th was charter schools with an effect score of 0.20.

So reducing class sizes has much the same impact as charter schools – a mild improvement.

So how on earth can Labour be vowing to abolish charter schools, yet put hundreds of millions into reducing class sizes?

The answer is the former policy results in fewer teachers in unions, and the latter results in more teachers in unions.
