For various reasons, people leave the classroom or the school or the district or the state department of education, and for various reasons some of those people then launch themselves as consultants. So far, so good. Free market. Willing seller, willing buyer and so on. However, not all who were once in education at any level good consultants make, and someone who is good at one thing may not be able to guide or to mentor in another. Some "consultants" can actually do real harm.
