Visible Learning MetaX
by John Hattie

When John Hattie first began his research around performance indicators and evaluation in education, he had one simple question: which variables have the greatest impact on student achievement?

The Visible Learning^TM research base is the culmination of his quest over the past 25 years to answer this question and represents more than 1,600 meta-analyses comprising more than 96,000 studies involving more than 300 million students around the world.
