[Lerc]

Buildings don't relate to student scores, they relate to how many students you can teach. If the new buildings house the same number, as before but were actually required then they spent money on basic human dignity. If the buildings were not required, the money was wasted. That is the opposite of spending it on resources.

Teachers, more of them, with more training is one of the main things that is needed. Increase the amount of one on one time. Adjust the curriculum to what each student needs. Measure the improvement in individual students, not the improvement in the mean of the lot of them.

Only teach things after the principles that they depend upon have been learned.
