If a teacher manages to cover all of the material in the curriculum, or more or less than that, it is not all that significant.
But if a teacher succeeds in teaching children how to do things properly, that is an achievement.
With time, such children will be able to close any gap.
To create a fine human being, even if that human being has less formal education than the average student in the other school – that is really worthwhile.
–Rabbi Adin Steinsaltz
