RFT for Educational Psychometric and Technical Expert Services using large scale Item Response Theory (IRT)

Description

In summary, this covers the provision of expert guidance and support (tailored capacity building/training and worked examples such as workflows, processes, programming code) in four areas of strategic importance to the work of the ERC, with these to be agreed by way of annual workplans i.e. • Development and application of Item Response Theory (IRT) or other appropriate psychometric scaling models to large-scale national assessment cognitive test data in line with best international practice, including weighting, conditioning, plausible values methodologies, and standard setting/proficiency banding; • Application of appropriate scaling models to generate robust questionnaire indices and scales; • Provision of guidance and support to the ERC in helping it to achieve the strategic goal of broadening the range of school-based tests from standardised and norm-referenced tests to others, including diagnostic or criterion-referenced tests; • Enhancing its application of online/web-based assessment technologies for school-based tests, particularly as these apply to scoring and reporting function This will involve demonstrating capability to advise, train nominated personnel in the techniques relevant to the tender subject matter and consult on deploying the services of the ERC via on-line tools.
