We've done it 3 times during F & W in the past... 2nd, 3rd & 6th grade.......They were only out of school for (2) full days & (1)- 1/2 day ...The early years it wasn't a big deal, but in middle school the last time, my son's math teacher sprung a PoP Test on material that she never even gave him time to learn. Well, needless to say he got a score of 10( & no way to improve or make it up ). This brought his average to an 89.instead of a 91....He never let us here the end of it because till that point, he never got a B in any marking period before. And the only thing the teacher could say to us was, " Well Mr. & Mrs. ------, Unfortunately that's the risks you take when you decide on pulling your kids out of school... We were like really..all he needed was 5 minutes & he would've learned that. When I told my twins that were were going again this Nov. there was a little apprehension, because he really wants to get into a prestigious H.S. My daughter who also is n excellent student was like, Ehhh we're only missing 2 days ( NO BIG DEAL )..LoL That's my Kid.. To make a long story short, I do believe this will be out last Fall trip for a lil while sad to say....
