Ah! on Thanksgiving day, when from East and from West, From North and South, come the pilgrim and guest, When the gray-haired New Englander sees round his board The old broken links of affection restored, When the care-wearied man seeks his mother once more, And the worn matron smiles where the girl smiled before. What moistens the lips and what brightens the eye? What calls back the past, like the rich pumpkin pie?
In the current environment, attributing low student performance to teacher tenure is one of the great unproven causal links out there. The relationship just hasn't been examined very carefully, but we should all recognize that in higher education the strongest institutions generally have the most robust tenure systems, and in elementary and secondary, the states with the strongest teacher unions (and tenure systems) tend to have the highest student performance.
