Scott McLeod Paul Schlangen (He/ Him) Matt Townsley Thomas Guskey Tom Schimmer John Hattie Susan Brookhart Cathy Vatterott Ken O'Connor Douglas Reeves Rick Wormeli Retention is not an intervention. See Hattie’s list of influences for the effect size from his meta analysis of this influence. Spoiler: it’s -.32. Not only is it not helpful, retention harms students. They don’t need more of what didn’t work, but instead intervention on skills.
