Many reasons. No control over unruly children. Couldn't find a permanent teacher for one class, at all. No one would stay. Students got other student's grades, not enough grades for the term, until I told them to search for papers and fix it all. They did, sort of.
In the end, grades were adjusted due to no teacher that would stick around and during awards ceremony, my kid got the A/B Honor Roll Certificate, even though her report card that I received later showed all A's...... NICE. NOT GOOD. Horrible experience for my child.
Wynnton is a great school with a wonderful staff and faculty. They treat your children like family. My oldest has started Kindergarten there and just completed first grade. Her teachers have been amazing. The arts-integrated circculum offers a unique learning experience my child has benefited from. Don't let the 4 out of 10 fool you. Wynnton is wonderful. I can't say enough great things about the school. The arts classes have been an opportunity we couldn't afford on our own. Dance, drama, art, and music. Take those classes outside of the public school, and you will pay a lot of money.
My daughter strived to make All A's after her first report card had two. B's. She succeeded and kept All A's the rest of the year. Her reading improved greatly too. She couldn't have done that without encouragement from her teacher.
