Hello all, Hoping someone might be using the Essentials Curriculum or other Chris Quigley materials and be able to explain how they work and share what they think of them. There seems to be a lot of additional books on the website intended to tie in with the Essential Curriculum - do you have to buy those as well? What staff training requirements are there? And is there a separate Milestones Curriculum or have I invented that/confusing myself with the Cornerstones Curriculum? Thanks in advance.
