What is efficacy?

At its heart, efficacy is looking at a way of doing something and asking ‘Does this achieve what it’s meant to achieve – and why?’   

This inquisitive, evidence based approach is at the heart of everything we do. We don’t assume something works just because that’s how it’s always done. We use research to find out what works and why.   

That’s why you can trust Pearson to help you reach your learning goals.
