While we indeed speak to some companies in this field, I want to point out that Screeps is not an education platform but an entertainment for already established programmers. We have never had, and we will not have any plans to add any education mechanisms for beginners, be it JavaScript or programming in general. Instead, we provide an interesting experience for application of your programming skills. It could motivate beginners in some way, but still it’s more of interest to mature programmers. Screeps and projects like Khan Academy have very different audiences.
As for the achievements, yes, we do have such plans.
