I joined Cambridge University Press & Assessment ARD in October 2022. I am a mixed-methods researcher with a broad range of interests in educational assessment. I am currently involved in several research projects, one of which investigates the effects of COVID-19 pandemic on high stakes assessments in several jurisdictions.

Prior to joining the ARD team, I worked as a research assistant at the Department of Linguistics and English Language, Lancaster University. I was involved in several research projects, including linking a suite of English language speaking tests to an external framework and researching the needs and use of English in the workplace in Sri Lanka.

I have a master’s degree in English Language Teaching with a specialism in Testing and Assessment from the University of Warwick. I am currently finishing my PhD in Linguistics at Lancaster University. My PhD research investigates the scoring of integrated reading-into-writing performance using analytic rating scales. I currently serve as a postgraduate research network officer for the UK Association for Language Testing and Assessment (UKALTA).

When I am not working or doing my PhD, I enjoy spending time with friends, baking and playing badminton.

Accessibility of GCSE science questions that ask students to create and augment visuals

Lestari, S. (2025). Accessibility of GCSE science questions that ask students to create and augment visuals: Evidence from question omit rates Research Matters: A Cambridge University Press & Assessment publication, 39, 39-65. https://doi.org/10.17863/CAM.116169

The ability to draw visual representations such as diagrams and graphs is considered fundamental to science learning. Science exams therefore often include questions which require students to draw a visual representation, or to augment a partially provided one. The design features of such questions (e.g., layout of diagrams, amount of answer space) could, however, influence students' ability to respond to the questions and present potential accessibility issues, which in turn could influence the validity of score inferences. This article reports on a small-scale study examining the accessibility of GCSE science questions involving the creation and augmentation of visuals (e.g., adding an element to a partially provided diagram) by analysing the patterns of question omit rates. Omit rates for questions involving creating or augmenting visuals were compared to those for questions without, and these comparisons were conducted across tiers, subjects, question position, maximum marks and facility values, as well as by gender and attainment group.

Does typing or handwriting exam responses make any difference?

Lestari, S. (2024). Does typing or handwriting exam responses make any difference? Evidence from the literature. Research Matters: A Cambridge University Press & Assessment publication, 38, 66-81. https://doi.org/10.17863/CAM.111629

Despite the increasing ubiquity of computer-based tests, many general qualifications examinations remain in a paper-based mode. Insufficient and unequal digital provision across schools is often identified as a major barrier to a full adoption of computer-based exams for general qualifications. One way to overcome this barrier is a gradual adoption, involving a dual running of paper-based and computer-based exams. When an exam is offered in both modes, and results from both are treated as equivalent, the comparability between modes needs to be ascertained. This includes examining whether the mode in which students respond to extended writing questions such as essays, either by handwriting or by typing on the computer, introduces systematic differences. This article presents findings from a review of existing literature on writing mode effects. Specifically, it discusses findings on four comparability aspects: scores, marking, text characteristics and composing processes. It also offers recommendations for practice.
