New Mexico – Gov. Susana Martinez has signed into law a major piece of her educational reform agenda.
The bill approved in the waning hours of the legislative session allows for grades from A to F to be assigned to New Mexico's public schools based on student performance.
That includes their performance on standardized tests and graduation rates.
Supporters say the grades will provide better information to parents about the quality of local schools.
Opponents have argued the legislation leaves too many details to the state Public Education Department, such as developing the standards for what constitutes each of the A-to-F grades.
An advisory group of school superintendents will have a voice in developing those guidelines.
The signing ceremony took place at an Edgewood elementary school on Tuesday afternoon.
