Coaching is better than training, but there is still a questionmark on scalability

"So should governments switch to frequent coaching sessions? Possibly, but the next step should first be to try this type of intervention at scale. 

Finding three highly skilled coaches is one thing, but you might need hundreds or thousands of them if you were to run a similar programme across an entire country. 

One potential route to scale is through new uses of technology. A study in Brazil found positive impacts of a virtual-coaching programme run via Skype, for example. 

But perhaps the most straightforward type of technology to go for is scripts, which this paper suggests have positive effects on learning both when presented through centralised training and intensive coaching."
