Further to my post, I would be wary of a pre-school setting where none of the staff had these GCSEs, which it seems would be possible for non-school-based settings under the new proposals. Requirements for reading and comprehending the impact of legislation, curriculum proposals, SEN reports etc, plus knowledge of finance, would seem to me to be an issue where no staff had these school qualifications.
However, I wouldn't have a problem with a setting where some of the staff were less academically qualified, provided that their skills and attitudes, in terms of working with children, were of the highest quality.
I've just looked up the excellent committee-led pre-school that my children attended. Staff qualifications range from BA / PGCE (secondary), through nursery nursing, via a healthcare qualification followed by a Level 3 childcare qualification, to a science graduate who has then acquired a Level 3 childcare diploma while working their way up at the Pre-school. Did their level of paper qualification match their excellence as childcare practitioners? No - all were equally strong, regardless of their initial 'academic' starting point.
