The gold-standard for evaluating the effect of an educational intervention on student outcomes is running a randomized controlled trial (RCT). However, RCTs may often be small due to logistical considerations, and resulting treatment effect estimates may lack precision. Recent methods improve experimental precision by incorporating information…

Purpose: This paper argues that in a well-organised school with strong leadership and vision coupled with a concerted effort to improve the teaching performance of each teacher, student achievement can be enhanced. The purpose of this paper is to demonstrate that while macro-effect sizes such as "whole of school" metrics are useful for…

Background/Context: Two key uses of international assessments of achievement have been (a) comparing country performances for identifying the countries with the best education systems and (2) generating insights about effective policy and practice strategies that are associated with higher learning outcomes. Do country rankings really reflect the…

Understanding how well English education performs compared with other countries is a valuable exercise, particularly because the information can help England and other countries learn from successful systems. The most recent international league tables of pupil performance differ considerably. England languishes well down the list in PISA 2009,…

In most PISA-participating countries and economies, the average socio-economic background of students who attend privately managed schools is more advantaged than that of those who attend public schools. Yet in some countries, there is little difference in the socio-economic profiles between public and private schools. Why? An analysis of PISA…

It is established that the socio-economic status (SES) of individual students is strongly associated with academic achievement but less is known about this relationship when both student and school socio-economic status are considered. To examine these associations at a finer grain, with the intent of informing educational funding policy, we…
