Case study with DESS: Meaningful data and marginal gains

Return to previous webinars

This webinar is hosted by Sarah Chandler – Education Services Consultant at GO 4 Schools, a COBIS Supporting Associate, and Joe Roberts, Assistant Headteacher at Dubai English Speaking School and College (DESS), a COBIS Accredited Member (BSO) school.

During this webinar we explore strategies employed by DESS to drive significant improvements in pupil outcomes.

Inspired by the British cycling concept of marginal gains, we'll show you how to move beyond generic grade data and implement whole-school systems based on item-level data. This shift allows for more granular analysis, helping you to pinpoint specific knowledge gaps and identify key students for targeted interventions.

Drawing on research and best practices, we explore effective strategies, including designing assessments, interpreting data, and triangulating various data points—like attendance and behaviour—to create a holistic view of each student. Discover how increasing data specificity can lead to meaningful, school-wide improvements.
