With any private school, faculty are not required to get education degrees. With many schools, they base academic credibility on their performances in college, pairing Biology majors with science classes, etc. Regardless of whether or not a teacher has had training in education, it takes a long time for a teacher to develop the craft of teaching. If you want to improve the quality of teaching at any institution, find a way to keep teachers there.
At Hyde, it's no different. Maybe more pressure should be put on the school to train their new teachers or to hire more experienced faculty members. However, teachers everywhere are becoming more discgruntled these days due to low pay, bigger classes, less respectful students and most importantly, parents who constantly intervene on behalf of their kids and prevent teachers from failing anyone. I am so glad I don't teach and have total respect for anyone who would these days.
