The Bildung Rose was first described in English in this article published by Nordic Bildung in October 2019: http://nordicbildung.org/publication/the-bildung-rose/
In June 2020, it appeared for the first time in print in English in my book Bildung: Keep Growing: http://nordicbildung.org/books/bildung/
The model itself is a lot older, though: it first appeared in Danish in my 2007 book Baade-Og Onsdag (Both-And Wednesday) — the third volume of a five volume series called Baade-Og (Both-And).; you can read more about those books here: http://www.baade-og.dk/english/.
Over the years, I have presented the model in numerous keynotes and everywhere have I experienced how people almost light up when I explain the model. It just connects so many dots and makes so much sense.
