In Teacher Layoffs, Seniority Rules. But Should It?

Larry Abramson:

School districts around the country are planning massive layoffs as they struggle to bridge big budget deficits.
And as they select which teachers go and which ones stay, many can only use one factor as their guide: seniority. Many districts will have to cast out effective teachers, because local contracts and even state laws require it.
Like many of his counterparts around the country, Cleveland schools CEO Eugene Sanders is facing a monster $54 million spending gap.
According to Sanders, there’s no room left to trim, and he may have to shed more than 500 teachers. He says that when he sent out pink slips earlier this year, he had no flexibility.
