Wow...sounds like a definite disconnect somewhere. Not sure what to tell you, but scorched earth probably doesn't improve the situation in any way. I can also understand that doing nothing would not be satisfying either. Out of curiosity, did you ask how many teacher rankings were included in the scoring? Did it include all of his teachers over the 4 years, or just recent ones? Anytime we rate a student low in some area at my school, we are asked to add commentary to elaborate as to why. Not sure if your school does that...if they do, I doubt they want to share the commentary with you, but maybe you could ask them to anonymously share some commentary at least for the purpose of understanding what is going on with your son.
I got more out of them than I expected, mostly because I wasn't banging the drum that they had to take my kid into NHS. I said I wanted to better understand the process and figure out some reasons why he didn't get in. They tried to give me the line that there are 4 pillars and he didn't meet them. I indicated I thought I knew about the process, went over what I knew, and then asked them to go line item to review what happened. I told them I didn't want them to disclose any anonymous or confidential information, but could they summarize what some of the feedback was.
They claim that most of the time freshman teachers elect to not participate in the NHS process because the kids are often immature at the time. However, those comments count the same as a senior teacher should anyone have provided some. I forgot to ask how many teachers participated. It could be a case of a lot of the teachers that would have given him rave reviews didn't participate and only they ones that didn't care for him did. But they did in general terms say that multiple teachers felt he was disrespectful to both teachers and students, bragged about how well he did and put down others that did not do as well, and called others names when he did better than them.
I followed up with that with my son, who explained he would never put down a "regular" student and that he and his closest friends CONSTANTLY act like that with each other. So if his BFF missed a simple question on a test, he would call him a dumba$$ for missing such an easy question. They all do that on his sports teams, too, and they constantly call themselves names when they screw up.
The good news is my wife sees the system as being so flawed that she now wants to drop it. My son, however, is really fuming about the situation. He says he hangs out with and talks to all his teachers, past and present, all the time. They corner him in the hallway to talk, several have asked him to come by and help with a unit that he did well in, and he often eats breakfast or lunch with his teachers. He could only think of 3 teachers that ever had anything even remotely inflammatory, so he's peeved that some of the teachers he is still buddy buddy with are giving him negative feedback.
He on his own is now compiling all his facts and information and plans on sitting down with the principal to illustrate that the whole process is flawed. As an example, he wants to show what teachers posted on his report cards or papers. That certain teachers nominated him for awards that he won in school. That papers he wrote were submitted for other academic awards. Basically, that every one of his teachers told him how well he was doing and went above and beyond to further his recognition or had him help his teachers with their other students. Again, he just wants to know how teachers are his BFF's one day and shooting him down the next and he doesn't like the veil of secrecy being the obstacle to finding out what his teachers said about him.
