Last year, Dallas told teachers not to give a grade lower than 50 for any grading period, so students who fail can hope to bring up their grade for the year in the next semester.
So do nothing and get at least a 50. There's more and you can read it here. My wife, who retired from a local ISD said that organization has a similar rule. She says she is so glad to be free of that whole scene -- students, administrators, parents, and all. Public schools in Texas may be doomed.
And I had a similar moment when the first flesh-eating bacteria story of the year showed up in the Vicad. Such a relief not to have to write those annual stories.
