I dunno. But start with the part at the beginning of what I quoted - is the story true? From https://www.ksat.com/news/2018/09/26/district-blasts-fired-teacher-says-there-is-more-to-story/ https://www.ksat.com/news/2018/09/26/district-blasts-fired-t... . > She wrote a note to her students on her final day on her classroom whiteboard that reads: > “Bye kids. Mrs. Tirado loves you and wishes you the best in life! I have been fired for refusing to give you a 50 percent for not handing anything in. Mrs. Tirado.” > KSAT reached out to the school district, and a spokesperson responded saying, in part: > "Ms. Tirado was released from her duties as an instructor because her performance was deemed sub-standard and her interactions with students, staff, and parents lacked professionalism and created a toxic culture on the school’s campus. > During her brief time of employment at West Gate, the school fielded numerous student and parent complaints as well as concerns from colleagues. Based on new information shared with school administrators, an investigation of possible physical abuse is underway." > The spokesperson also mentioned the schools grading policy, stating that there isn’t any policy prohibiting a teacher from recording a zero for work not turned in. You write "someone getting 50% makes me assume he passed 50% of the things" but surely you know that's not the way things work. Some of my teachers had a policy to drop the lowest score before computing the GPA. That doesn't fit your view. Many of my teachers had a way to get extra credit. That doesn't fit your view. Teachers don't have perfect calibration either. In one test I got 40% right, which was the highest score in the class.
