Assessment development, Management and running of large-scale monitoring systems in pre-schools and primary schools, Research methods and evaluation in education, Achievements of severely inattentive, hyperactive and impulsive young children.


  • Developed assessments for children aged 3 - 14 years including assessments of reading, mathematics, English vocabulary, non-verbal ability and motor development. Most recently developed a computer-delivered, adaptive diagnostic assessment of reading for children aged 5 - 11 years. This included generation and analysis of items.
  • Managed large-scale assessment systems which monitor children's progress in pre-school and primary school. This involves the development and delivery of assessments, marking, analysis and provision of pupil-level feedback.
  • Studied the achievements of severely inattentive, hyperactive and impulsive young children, including involvement in a large-scale RCT to evaluate the impact of interventions aimed at helping such children succeed in the classroom.
  • Evaluated a range of educational interventions.
  • Provided in-service training for teachers, education authority personnel and other professionals in relation to assessment, monitoring pupils' progress and evidence-based interventions to help children succeed at school.

Christine has extensive experience in the development of assessments (for example reading, mathematics, vocabulary) for children aged between 3 and 11 years. She has published research about the development of children in the early years and the prediction of their later attainment, including children who are deaf and hearing impaired. Her other research interests include the academic attainment and progress of severely inattentive, hyperactive and impulsive young children and ways to help them succeed in the classroom. She would be delighted to supervise post graduate research students in these broad areas.

The development of an assessment to identify deficits in facial expression decoding in young children


Research into the attainment and progress of severely inattentive, hyperactive and impulsive children, and interventions to help them succeed in the classroom. Co-I on a large-scale intervention study involving 2040 schools in England, which evaluated different school-based interventions. One of the interventions, an advice booklet to teachers which contained research-based teaching and classroom-management strategies, was found to have a long-term positive impact (up to GCSE) on children's attainment. The results from this study significantly shaped the recommendations in National Clinical Practice Guideline Number 72 commissioned by the National Institute for Health & Clinical Excellence (NICE) and published in 2008. For the first time ever, in any of their guidelines, NICE included advice for treatment in educational settings. The study was one of only six educational studies from around the world considered to be of sufficiently high quality to meet NICE's inclusion criteria for this guideline.
