SDI Evaluation | Summary

Evaluation of Same Day Intervention

We are evaluating Same Day Intervention, an approach to teaching in which teachers restructure their maths lessons to understand if it makes a difference to pupils.


What is Same Day Intervention?

Same Day Intervention (SDI), developed by Yorkshire and the Humber Maths Hub,  is a new approach to teaching maths in which teachers restructure their maths lessons, to understand if it makes a difference to pupils in Year 5.

NatCen are conducting an independent evaluation of Same Day Intervention (SDI) to find out what difference the new structure has on pupils and teachers in Year 5.

You can find out more about SDI here.


Why evaluate the intervention?

Yorkshire and the Humber Maths Hub have implemented Same Day Intervention in a small number of schools in the region and found pupils and teachers to have a positive experience of the new structure of teaching maths.

NatCen are conducting an independent evaluation which will find out what impact Same Day Intervention has on pupils’ mathematical ability.

We also want to know what enables or stops the successful delivery of Same Day Intervention, as well as teachers’ experience of implementing the programme.

Comparing an intervention group to a control group allows the study to provide robust evidence on the impact of the programme on pupils’ mathematical ability. By participating, your school will be making a valuable contribution to building evidence for what works in education.

The trial is being funded by the Education Endowment Foundation.


What does the evaluation involve?

A total of 120 schools will be invited to take part in the evaluation. Schools will be randomly assigned to a treatment group that delivers Same Day Intervention or a control group that does not deliver the programme and continues with the current best practice in maths teaching.

Schools assigned to the control group will receive £1,000 as a thank you for taking part in the trial.

The trial will take place over the 2018-2019 school year and involves:

  • A survey of teachers before and after Same Day Intervention is delivered in schools (treatment and control schools)
  • An assessment of all Year 5 pupils towards the end of the summer term 2019 (treatment and control schools)
  • Case study research in treatment schools. This will involve us speaking with teachers delivering Same Day Intervention, Teaching Assistants who support the delivery, and Head Teachers, as well as small discussion groups with Year 5 pupils.
  • Telephone interviews with staff in control schools

Before the trial starts, all schools will be asked to complete a pupil information form, which asks for basic details of all Year 5 pupils in the 2018-19 school year.

If you're representing a school, and would like to find out more about what's involved, we have more information for you here.


How do I get involved?

Primary schools in Yorkshire & the Humber (including the surrounding areas) can apply to part of the trial if they meet the eligibility criteria and are committed to engaging fully.

To be eligible for the trial, your school should:

  • Have at least one Year 5 class in the 2018/2019 school year with no Year 5s taught in mixed-year group classes
  • Not have been involved in Same Day Intervention to date
  • Be located in the Yorkshire and Humber or surrounding areas
