More about Randomised Controlled Trials (RCTs)
Schools that sign up to an RCT are allocated to one of the available groups in a random way (the equivalent of flipping a coin). This means that any characteristics that schools have should be evenly spread across the different groups taking part in the trial. Random allocation is essential to the evaluation as it shows that any difference seen in ‘intervention’ or ‘treatment’ schools is because of the intervention and not any other factors. Therefore, an RCT can be the best way of outlining what effect an intervention has on children’s attainment.
