I have reported in another thread that at the PLA conference Ofsted said they had received interest about agencies from:
Head teachers
LAs
Employers (not sure who these are)

and in addition we know who is on the list given by Truss:

Ofsted,
the National College for Teaching and Leadership,
4Children,
Family and Childcare Trust (previously Day Care Trust)
National Day Nurseries Association,
National Children’s Bureau,
Pre-school Learning Alliance,
Northamptonshire Childminding Association,
Norland College,
Independent Childminders Social Enterprise,
Bright Horizons,
Busy Bees,
Kidsunlimited,
Association of Nanny Agencies,
ARK Academies,
Redgrave Children and Young People’s Centre,
Trio Childcare
@Home Childcare.

Specific individuals attending from these organisations vary from meeting to meeting (We assume these are by invitation)

I have spoken this week to people who head these groups such as NDNA, Family and Daycare Trust, PLA, 4Children
All have said they are concerned about agencies ...so maybe they are not developing them but also listening and expressing worries???

Maybe worth writing to them
I will post this on the AGENCIES thread so cms can see at a glance who they are
