In 87' my son attended Lake Otis Elementary, second grade. It was an average size 2nd grade class of 30 or so well minded children. The teacher was young, with seven years under her belt. There was something defeated about her that made me wonder though. I didn't give it much thought at the time, but in a short amount of time I would learn the harsh reality; half of the class could not read at grade level. 
I met the young teacher a few days before classes resumed, to get acquainted and lend my support, she gladly accepted my offer to volunteer as needed. 
My volunteer assignment was to read to 10-12 children, I think it was three times per week, and it lasted for half the school year. 
I tried for two years to get my son into Polaris, but the system favors teachers and siblings. We had no choice but to stick it out at Lake Otis.
Why are we moving children to the next grade level when they are already two levels behind is beyond me. 2017 and nothing changes
