Frequently asked questions
About the case studies and how the figures work. More in our full FAQ.
Does management training improve manager confidence?
In the World Class Manager® data it does, in every sector shown here. Across these ten organisations, average manager confidence rose from 73% at the start of each module to 95% at the end (17,254 matched ratings, 1,889 managers). Across all 177 organisations in the matched data it rose from 71% to 94%.
What is World Class Manager®?
World Class Manager® is a CPD-accredited management development programme from the Global Growth Institute. Managers work through online modules in two series, Foundations and Advanced, answering reflection questions and committing to actions with their own teams. It has reached more than 250,000 managers in over 50 countries.
How is the confidence score measured?
At the start of each module, every manager rates themselves on the module’s core skill. At the end of the module, they rate their confidence again. Both ratings are turned into a percentage of the top of the scale, matched for the same manager and module, and averaged. The score is self-reported: it shows how managers rate themselves, not business outcomes.
Are these results typical?
Yes. Across all 177 organisations in the matched data (28,460 ratings from 3,397 managers), average confidence rose from 71% to 94%. Every one of the 35 organisations with 15 or more managers in the matched data saw a rise, of between 16 and 34 points.
Why are the organisations not named?
World Class Manager® records are pseudonymised and client data is confidential. Each case study names the sector and region only. Quotes are verbatim, with no names, and are shortened only where marked.
