You cannot use or implement the standards without a book that first says what each standard is and what it really means. This is that book and it is the first and most complete work out there since the author was the primary architect of the new standards. Implementation is the next generation. It really requires a book on each standard to get it right. UCEA did this for the old standards -- one book on each of the six ISLLC standards. A similar series here would make sense but the lead volume needs to be done first. It would be more for people teaching professionals and for development people creating products. This will be the go-to manual on the standards- outlining each of them in clear terms and defining them with examples from practice.
