Jo is a statistician in the Centre for Statistics at NFER. She has worked in the field of educational statistics for over 10 years, analysing data that arises from numerous sources; via surveys, aptitude and ability tests and administrative data such as the DfE’s NPD and ILR. Jo has experience of utilising a wide variety of analysis techniques, from the simple crosstab to more sophisticated models. (e.g. multilevel models or item response theory to elicit patterns and test hypotheses.)
Recent work includes:
- The analysis elements of the OECD's PISA-based Tests for Schools in the UK; which includes cognitive item scaling using IRT to anchor item parameters while conditioning on student background information, followed by the generation of plausible values, latent class analysis of reader profiles, multilevel modelling to adjust for economic, social and cultural status (ESCS), and balanced repeated replication to calculate school level results
- Fitting IRT models to inform item selection and to link tests forms, followed by age-standardisation, for a suite of science tests
- Multilevel models, in a quasi-experiment design, to ascertain whether tutoring is associated with increased attainment in mathematics and English GSCEs
- Regression analyses of the European Survey of Language Competencies, to determine which student and school background characteristics are associated with foreign language competency, measured using plausible values and levels
- Factor analyses of questions measuring parents' satisfaction with their child's education, followed by linear and logistic multilevel regression for the National Survey of Wales 2012-13.
As well as conducting analysis, Jo advises on the collection of data to ensure that resulting information is suitable, she trains research colleagues in statistical techniques and use of software, she interprets results and present findings in written and graphical forms. She is a Chartered Statistician, a professional qualification awarded by the Royal Statistical Society.
