Ba'ruch habah

Being a Rabbi (teacher) is one of the most rewarding professions there is. In my personal experience, I found that it opens doors to re-learn, re-explore and exchange some of life's most memorable moments while at the same time creating life-time bonds with your students. 

Again in my personal opinion the top qualities for good teachers to have include the following:

• Faith
• Effective goal-setting
• Clear communication
• Acting as a role model
• Adaptability and flexibility
• Preparation
• Self-reflection
• Lifelong learning
• Promoting a love of learning

As a parent myself,  I would focus on what I call three aspects of teaching: preparation  for classes, teaching in the classroom and communication with parents and other teachers.  As a parent it is well within the rules for you to ask about their personal teaching plans and how effective these methods have been in the past. Isolate some different everyday situations and ask them briefly explain how they would handle them.
