Public schools in Louisiana will get letter grades based on performance starting in the fall. Board of Elementary and Secondary Education President Penny Dastugue says based on spring performance scores, nearly half of Louisiana schools would receive a "D" or "F" under the new letter grade system. Dastugue says the grade letters are being used so that parents and leaders can get a better understanding of how schools are performing in their communities. She says the current star system is not as effective. Dastugue says she believes the grade lettering system will be more compelling to parents and will give public schools more transparency. Dastugue says Louisiana public schools are improving at a very slow pace.
