NPR reports that thousands of teachers who received grants under the federal TEACH program recently discovered that they had been converted to loans, with interest accruing. What a disgrace! America needs teachers committed to working with children who have the fewest advantages in life. So for a decade the federal government has offered grants — worth up to $4,000 a year — to standout college students who agree to teach subjects like math or science at lower-income schools. That's despite the fact they were meeting the program's teaching requirements."Without any notice, [my grant] was suddenly a loan, and interest was already accruing on it," says Maggie Webb, who teaches eighth-grade math in Chelsea, Mass. "So, my $4,000 grant was now costing me $5,000."
