澳大利亚维多利亚州的高中科目缩放机制正面临公平性质疑。根据2025年数据，所有获得完美ATAR成绩99.95的学生均选择了两门最难的数学科目1。这一现象反映出缩放制度对学生科目选择的深刻影响，同时也揭示了教育不平等的问题。
缩放算法旨在使不同科目的成绩具有可比性，但实际效果却因科目间的巨大分差而产生问题。以2025年维多利亚州为例，化学原始分数30分（满分50分）被缩放至34分1，而拉丁语则成为缩放最高的科目，原始分数30分同样被缩放至46分1。与此形成鲜明对比的是，农业和园艺研究即便原始分数达到40分（属前10%），也仅被缩放至34分1。
这种缩放差异进一步强化了现有的教育不平等。低社会经济背景的学生更可能选择缩放分数较低的科目1，最终获得较低的ATAR成绩，升入大学的可能性也因此更小。值得注意的是，拉丁语仅由少数高中提供，其中许多是私立学校或服务于特权学生的学校1，这使得获得高缩放分数的机会本身就存在明显的结构性障碍。
Australia's Victorian Year 12 system uses subject scaling to make grades across different subjects comparable for ATAR (Australian Tertiary Admission Rank) calculation.1 In 2025, all students who achieved a perfect ATAR score of 99.95 in Victoria selected the two most difficult mathematics subjects, revealing how scaling shapes student choices and outcomes.1
The scaling mechanism adjusts raw scores based on subject difficulty and cohort performance.1 For example, in 2025 a raw score of 30 out of 50 in chemistry scaled up to 34, while a score of 40 out of 50 in agricultural and horticultural studies—placing a student in the top 10 percent—scaled to the same 34.1 Latin achieved the highest scaling that year, with a raw score of 30 out of 50 scaling to 46.1 Chemistry's scaling increased in 2025, while agricultural and horticultural studies scaling decreased.1
Critics argue the system reinforces existing educational inequality rather than mitigating it.1 Students from lower socioeconomic backgrounds are more likely to select subjects with lower scaling scores, resulting in lower ATAR outcomes and reduced university admission prospects.1 This disparity is amplified by access: Latin, which receives the highest scaling adjustment, is offered by only a limited number of high schools, many of them private institutions or schools serving privileged student populations.1
