Harmonized Test Scores

Harmonized Test Scores from major international student achievement testing programs. They are measured in TIMSS-equivalent units, where 300 is minimal attainment and 625 is advanced attainment. Most recent estimates are used. The year of the most recent estimate is shown in the data notes. Test scores from the following testing programs are included: • TIMSS/PIRLS: Refers to the average of test scores from TIMSS (Trends in International Mathematics and Science Study) and PIRLS (Progress in International Reading Literacy Study), both carried out by the International Association for the Evaluation of Educational Achievement. Data from each PIRLS round is moved to the year of the nearest TIMSS round and averaged with the TIMSS data. • PISA: Refers to test scores from the Programme for International Student Assessment • PISA+TIMSS/PIRLS: Refers to the average of these programs for countries and years where both are available • SACMEQ: Refers to test scores from the Southern and Eastern Africa Consortium for Monitoring Educational Quality • PASEC: Refers to test scores from the Program of Analysis of Education Systems • LLECE: Refers to test scores from the Latin American Laboratory for Assessment of the Quality of Education • EGRA: Refers to test scores from Early Grade Reading Assessments. This indicator is part of the Human Capital Index (HCI).

本数据集包含经统一校准的全球主要国际学生学业成就测试分数，采用TIMSS等价单位作为计量尺度，其中300代表最低学业达成水准，625代表高级学业达成水准。本数据集采用最新估算值，最新估算的年份将标注于数据说明中。

本次纳入统计的测试项目分数如下：
• TIMSS/PIRLS：指由国际教育成就评价协会（International Association for the Evaluation of Educational Achievement）开展的国际数学与科学趋势研究（Trends in International Mathematics and Science Study, TIMSS）与国际阅读素养进展研究（Progress in International Reading Literacy Study, PIRLS）的测试分数平均值。各轮次PIRLS的数据将被对齐至最近一轮TIMSS的对应年份，并与同期TIMSS数据计算平均值。
• PISA：指国际学生评估项目（Programme for International Student Assessment, PISA）的测试分数。
• PISA+TIMSS/PIRLS：指在同时拥有两类项目数据的国家及对应年份中，二者分数的平均值。
• SACMEQ：指南部与东部非洲教育质量监测联盟（Southern and Eastern Africa Consortium for Monitoring Educational Quality, SACMEQ）的测试分数。
• PASEC：指教育系统分析项目（Program of Analysis of Education Systems, PASEC）的测试分数。
• LLECE：指拉丁美洲教育质量评估实验室（Latin American Laboratory for Assessment of the Quality of Education, LLECE）的测试分数。
• EGRA：指早期年级阅读评估（Early Grade Reading Assessments, EGRA）的测试分数。

本指标为人类资本指数（Human Capital Index, HCI）的组成部分。如需获取更多信息，请查阅《全球教育质量数据集：2000-2017年回顾与更新》（帕特里诺斯与安格里斯特，2018）：http://documents.worldbank.org/curated/en/390321538076747773/Global-Dataset-on-Education-Quality-A-Review-and-Update-2000-2017
