MELISSA BLOCK, HOST:
Most of today's students and their parents are used to report cards based on the letters A through F. But a new grading system is taking root in schools across the country. It's called standards-based grading. The point is to give parents more information, as New Hampshire Public Radio's Sam Evans-Brown reports.
SAM EVANS-BROWN, BYLINE: Here's what we know about grades in America: A is good, F is bad. But what about these?
BRIAN STACK: We have like E, M, IP, and LP.
