A levels in England are moving from a modular to a linear system. Additionally, the AS and A level are being "decoupled", meaning that students will no longer undertake summative assessment at the end of the first year of study. Psychology may be particularly vulnerable to these changes as students often have no prior experience of the discipline. 768 current A level Psychology students responded to an online questionnaire about their decision-making at A level. Whilst subject interest was the primary motivator at AS level, decision-making was significantly more pragmatic at A level, as prior and expected attainment were the most influential factors. Additionally, students reported receiving very little advice about studying Psychology. These findings suggest that uptake of A-level Psychology is likely to be negatively affected by qualifications reform, but it may be possible to counteract this by ensuring students are informed about the benefits of studying Psychology.
