It's a good idea to push the lowest intelligence people as much as possible if you have to live in a mixed race society. As you know from The Bell Curve, there are low and high scores among all groups, while the median differs. A proper education is like an RPG buff that can add +X% "effective intelligence" to students in all groups. There are diminishing returns for lower IQs, but still some effect in aggregate - even among the stupids. What you're trying to avoid in any society is the really really low IQs tearing shit down and taking others with them. At least trying to teach comprehension, skills, and correct behavior reduces the likelihood of that.
I would prefer more individualized learning. There's no more point in measuring reading score across different demographics groups than there is measuring IQ across the whole nation.
