That improvement might come from all sources. Health and nutrition improvements can have very high impact. Deworming, using safer water. Contribution of education to this 15 points might be just few points.

It's not about IQ, also, was it ever replicated?

It certainly isn't genetics. You're not going to cause a population-wide one sigma increase within a single generation using any genetic mechanism.

Yes, this has been replicated repeatedly. As far as IQ, if you apply for a private school that uses IQ tests for admission, you will find that all of them explicitly forbid test coaching because it is well known that it works. Even a video will cause large gains. https://www.sciencedirect.com/science/article/abs/pii/S01602...
