Making sure evidence is robust and relevant.

WhatWorked is dedicated to bridging the gap between research, teachers, and EdTech by promoting evidence-based decision-making within the education sector. The company aims to create a continuously updated evidence base that supports teachers, school leaders, and intervention developers in making informed choices backed by the best available data.

To achieve its mission, WhatWorked focuses on the innovative use of small-scale mini-randomised controlled trials (RCTs) and aggregates the data from these trials into a cumulative meta-analysis evidence base. This method is both time-efficient and cost-effective, overcoming the traditional barriers of high costs and long timescales associated with educational research.

Evaluating the impact of EdTech

We work with EdTech companies to create an independent evaluation of the impact of their interventions.

Independent evaluation

Create robust evidence for the impact of your interventions in schools. 

Implementation Support

Develop specific guidance on the implementation process for your intervention. 

Rapid evaluations 

Set up small scale pilots in schools and then scale these once they demonstrate that they have a positive impact.


You can choose how to evaluate your interventions, including the option of setting up mini-trials. We even analyse the data for you.


Using our cumulative meta-analysis approach to aggregating data, build your evidence base for your interventions as more schools complete the evaluations. 

Cost effective

Most start ups do not have the funding to employ researchers to conduct impact evaluations. We provide a cost effective solution to allow you to develop an evidence base for the impact of your programmes.
