Book excerpt: The Hidden Dangers in our schools have grown and intensified over the last few years; so much so that I was compelled to write a second edition to Hidden Dangers: Subtle Signs of Failing Schools. Our schools are complex places; each with its own unique climate, administration, faculty, students, parents and community members. Clearly, schools do not work in a vacuum; each is affected by the much larger society, government and economy. In this new edition we will be introduced to the interplay of these facets and how they can help and in some cases hinder our schools, our teachers, and our students from thriving. We also learn why it is more complicated now than ever, and the stakes are even higher than when Hidden Dangers was originally published back in 2008
