Even worse is the similar pattern of

1. A school produces great results. 2. A consultant comes and mines that school for "best practices". 3. Other schools pay the consultant a small fortune to replicate those practices.

Where the successful school may not even have updated anything in the last decade; they just have a particularly good combination of dedicated staff, helpful administration, and well-supported students. Particularly bad is trying to replicate something from a suburban school full of privately-paid tutors and parents reviewing the nightly homework in a setting where lunch and school supplies are a major hurdle for many families.
