Governments harnessing the power of data to get ‘value for money’: a simulation study of England’s Office for Students B3 Proceed Metric
通过模拟研究评估英格兰学生办公室的进展指标能否准确识别低于60%阈值的高校课程，发现小样本下估计精度不足，可能导致错误分类。
The mass participation in higher education has led to greater spending by governments and students which has increased the focus on graduate outcomes. In England, the Office for Students (OfS) is planning to take regulatory action, using the Proceed metric, against universities and their courses which do not have 60% of students with positive outcomes within 15 months of graduation. This study uses simulations to explore how effectively the Proceed metric can (a) identify the true population level of positive outcomes, (b) explore the precision of those estimates, and (c) accurately classify courses below the 60% threshold. The simulation varied: level of positive outcomes within the population (20–90%), sample size (40–1000), and the percentage of the population sampled (30–90%). The bias (difference between sample and population estimate), coverage probability (proportion of true population estimates within the intervals), and precision of confidence intervals (average range of confidence intervals) were calculated. Three main findings were (a) the Proceed metric is accurate in terms of bias and coverage probability, (b) the estimates lack precision, especially with small sample sizes, and (c) the imprecision will impact the Proceed metric ability to correctly classify courses below the 60% threshold. Governments seeking to collect graduate survey data and use it to regulate universities should make every effort to maximise sample size and should resist the temptation to regulate at a micro-level (i.e. courses) since classification will likely be inaccurate, especially for those just below the threshold.
