Assalamoalaikum Warahmatullahi Wabarakaatuh I have worked in several Islamic schools over the last 3 years, and can appreciate all of the points raised in this discussion so far.
Indeed, we must strike a balance between positivity and constructive criticism.
Ultimately, the conduct of the management, staff and students all depends on the ikhlaas and akhlaaq of the adults. That of those who are responsible for themselves, and that of those who have their sub-ordinates.
I feel that it is crucial for all Islamic schools to be strongly affiliated with muttaqi ulama when it comes to managing the staff and also with professional institutions which can guide them towards adopting the most effective teaching practices through training and resources.
Islamic schools are increasing in number, and this is no doubt, a good thing. They also have their shortcomings which can only be addressed when the management of the schools open themselves to sincere advice. This ability to accept advice is rooted in humility which is a fundamental of akhlaaq... and this is what must be addressed first in both our young and old; men and women.
