Educational assessment postgraduate personal statement example

Personal statement example

My interest in assessment began with a small methodological problem in my undergraduate dissertation. I had written two versions of a short reasoning test, intending them to be equivalent, and changed only the phrasing of the instructions and two item stems. The version that used shorter sentences and a concrete example produced noticeably higher scores in my sample. My supervisor pushed me to be careful about what I could claim from thirty-eight participants, and that caution was useful: I could not say I had measured comprehension load, only that the wording difference coincided with a score difference. What stayed with me was how easily a test can measure something other than what its author intends, and how much technical work is needed to establish that it does not.

My psychology degree gave me the statistical grounding I want to build on. I enjoyed the modules on psychometrics and research methods most, particularly working through reliability estimates and factor analysis in R, and I found item response theory intriguing without having studied it properly. Reading Paul Black and Dylan Wiliam's work on formative assessment during my final year moved my thinking beyond measurement as a technical exercise; their argument that feedback only matters if it changes what a learner does next reframed assessment for me as part of teaching rather than a verdict on it. I have since read Christodoulou's Making Good Progress?, which was helpful in separating the things assessment can plausibly do from the things schools often ask of it.

Working in a further education college examinations office has been an unglamorous but instructive apprenticeship. I process entries, check candidate details against specifications, arrange access arrangements paperwork, and invigilate. It has taught me that the validity of a result depends on a long chain of ordinary administrative accuracy: a mis-entered tier, a missing reader, a clash resolved carelessly. I have also seen how differently colleagues interpret the same assessment information. Some tutors treat a mock grade as a prediction, others as a diagnosis, and the two lead to very different conversations with students. I would like to understand the evidence on standard setting, comparable outcomes and the limits of predictive accuracy well enough to contribute sensibly to those discussions rather than only administering them.

Volunteering as a reading helper at a primary school one morning a week has widened my view. I listen to individual children read and record brief notes for the class teacher, who decides what to do with them. Two mornings shadowing the school's assessment coordinator showed me the primary end of the system: she was reconciling termly reading assessment scores with teacher judgements and wanted to know why a group of children looked stronger on the test than in class. I mostly observed and asked questions, but it clarified what I want to study. She was doing, informally, the kind of triangulation that has a substantial research literature behind it, and had little time to consult it.

From the master's I hope for three things: proper technical training in measurement, including item analysis and equating; a critical understanding of assessment policy and its unintended effects on curriculum and teaching; and the ability to design and evaluate instruments rather than only interpret other people's. For a dissertation I am interested in the consistency of teacher judgements against test-based measures in primary reading, though I expect that idea to change once I know the field better.

After the course I would like to work in an awarding organisation's research team or in a local authority or trust role supporting schools with assessment design. Both need people who can read a technical report carefully and explain it to someone who has thirty children to teach on Monday. My background in administration, invigilation and volunteering means I already understand the practical constraints that good assessment advice has to respect.
