What sort of trial is KEEP Teaching?
KEEP Teaching is a randomised controlled trial and an efficacy trial.
What is a randomised controlled trial?
A randomised controlled trial is a study in which a number of similar people are randomly assigned to two or more groups to test a specific intervention. One group has the intervention to be tested.
The other group (the control group) has an alternative intervention, a dummy intervention or no intervention.
In the case of KEEP Teaching, the control group receives no intervention. Outcomes are measured at specific times and any difference in response between the groups is assessed statistically.
Schools were assigned to different groups without taking any similarities or differences between them into account.
What is an efficacy trial?
An efficacy trial tests an intervention under developer-led “ideal” conditions. This means that schools will be given support by the IOP in implementing the allocated intervention.
What does the KEEP Teaching trial involve?
As the KEEP Teaching trial is a randomised controlled trial, it is important that we don’t share too many details about the intervention until the trial has been completed at the end of the 2021-22 academic year. This is to ensure the control group continues ‘business as usual’ and is not influenced by ideas implemented in the intervention groups.
How were schools selected?
All schools that registered interest and met the eligibility criteria were invited to join the trial. UCL randomly allocated schools to an intervention or control group.
To participate in the KEEP Teaching trial schools had to be:
- teaching students aged 11-16 or 11-18; and
- state schools in England.
