Who is the focus of your trial?

For example: Year 7 pupils with a KS2 scaled score of less than 95 in maths. There are 24 pupils in this group: 17 of whom are boys, 19 are eligible for FSM.

Describe the study: intervention and control conditions

For example: The 12 pupils in the intervention group will be divided into two groups of six pupils. Both groups will receive two 20 minute sessions each week during tutor time in the first part of the autumn term - a total of 12 sessions over 6 weeks - led by teaching assistants (TAs). The programme has been designed by the maths department, who have trained and supported the TAs in delivering the programme. The programme makes use of question level analysis on the KS2 tests to target areas of weakness in mathematical understanding.

Each session will involve...

The 12 pupils in the control group will receive the intervention in the second 6 weeks of the autumn term after the post-test has been administered.

What is actually being changed?

Four additional hours of small group tuition by TAs are provided in mathematical concepts and skills. There is strong evidence on well-trained TAs delivering structured interventions, closely linked to classwork. It is expected that this additional support will provide a firm base for accessing the Year 7 curriculum in mainstream lessons.

What are the expected effects of your intervention or what do you hope to find out? 

The evaluation will hopefully show a small positive effect on mathematical understanding and skills after 6 weeks. If it does, it will demonstrate that extending TA contracts by an additional 30 minutes at the beginning of the day is likely to be beneficial.
