My husband and I were in agreement about the importance of sending our children to a Jewish day school.
Good teaching is what education is all about.
There is a teacher crisis in this country and it is not confined to your local day school. Teachers are not being adequately educated, trained or compensated. Changing schools will only mean you will face the same problem in a new setting. Stop wasting time debating with your husband and start drafting the parent body in a crusade to improve the quality of your teaching staff. Join the committee that vets teachers before they are hired.
