Plain English Summary

Background and study aims
The Incredible Years (IY) Teacher Classroom Management (TCM) course may enhance teachers' skills in promoting socio-emotional well-being among their pupils. Disruptive behaviour is a common source of stress among teachers, and a common reason for many leaving the profession. Poor socio-emotional adjustment in childhood may affect mental health and academic attainment and can adversely impact on life chances of all the children in a classroom, particularly children living in deprived circumstances. We will study whether delivering TCM to primary school teachers leads to improvement in children's socio-emotional skills and academic achievement. If effective, TCM could transform the classroom from an environment where many children currently struggle to cope, particularly boys from low socio-economic backgrounds, into one where many more children can thrive. Enhancing teachers' skills potentially benefits all children that come into contact with that teacher over subsequent years, so TCM may be a particularly cost-effective way to assist the most vulnerable children in our society.
The Supporting Teachers And childRen in Schools (STARS) study will test whether a teacher attending the TCM course will improve:
The child's socio-emotional well-being
The child's academic attainment
The teachers' emotional well-being
The teacher's belief that they are able to manage the behaviour in the classroom more effectively and feel less stressed

Who can participate?
Primary schools in Devon, Plymouth and Torbay will take part in the study, and the study will involve one teacher, their class and their parents. The study will work with teachers of Reception to Year 4, which means that the children will be aged 4-9 years at recruitment.

What does the study involve?
The research will take place in 80 primary schools in Devon, Plymouth and Torbay. One teacher from each school will take part in the study. Teachers will be randomly allocated to the intervention group and attend the TCM course or the control group and teach as usual. Control teachers will be able to attend the TCM course in the following academic year when they have a new class of children. TCM involves six one-day group sessions spread over six months with ten teachers in each group. The sessions will be led by behavioural support teachers trained to deliver TCM. We will measure socio-emotional well-being using a well-known and highly tested questionnaire - the Strengths and Difficulties Questionnaire (SDQ). The SDQ will be completed by teachers and the parents of all their pupils before and after the TCM course, and at one and two years after that. We will focus on teacher reports as we expect to collect more complete data from teachers, but we will also ask parents to give their view on the socio-emotional well-being of the child. Academic progress will be measured using the National Curriculum standard levels used routinely in all state schools and we will check these scores against detailed literacy/numeracy assessments in some children. We will also measure teachers' sense of effectiveness as a teacher, whether they feel 'burnt-out' and their emotional well-being to see if the course leaves teachers feeling more confident, motivated and less stressed. We will use a mixture of focus groups and interviews to find out from teachers, head teachers and special educational needs coordinators (SENCos) how useful they think TCM is, whether they use it in their practice and/or schools, and how it fits with other sources of support for emotional and behavioural difficulties. We will speak to them shortly after they attend the course and a year later. Using questionnaires completed by parents and SENCos, backed up by detailed interviews with some parents, we will find out about additional help used by families concerning their child's well being. This will try and identify any cost-savings that TCM might produce by reducing demands on educational support and mental health services.

What are the possible benefits and risks of participating?
Teachers will attend six days of high quality training in classroom behaviour management, a topic of great importance to schools. We have already delivered the TCM course to 40 teachers in smaller studies to prepare for the STARS study. These teachers said that they found the course extremely useful and highly relevant to their everyday teaching practice. An issue could potentially arise if a teacher feels that being suggested to attend the course is a criticism of their teaching practice or they may feel coerced to attend. However, this was discussed with the teachers who have already attended the course and many said that they were encouraged to go on the course by their Headteachers but none were coerced in any way. The study will pay for supply teacher cover to enable the teacher to attend the course and complete questionnaires, as we know that many schools would find it very difficult to pay for this themselves.

Where is the study run from?
This study is led by a team from the Child Health Group of the Peninsula Medical School in Exeter.

When is the study starting and how long is it expected to run for?
The study will start in September 2012 and will recruit schools over a three year period. Each school will take part for three academic years. Consequently, the study will run for five years in total.
