Childminders can elect not to be on the list as they may only childmind for family members or friends (I know a couple). Some just don't like their details being so freely available (I know a few more!)
I did think twice about allowing my phone number to be on it, as you can have the CIS number on it instead, but decided that it might put parents off ringing me direct in the first place.
I don't like the idea that it is so easy for people to find out exactly where I live. If you think about it too much, we are very vulnerable (mostly women at home on their own), so I try not to (think about it that is).
I also get very cross with the whole system. If parents don't know the postcode of the area they might be looking (near their work, on the route to work, on a particular side of town etc.), then they just end up - in my area - with being sent a list of all the childminders in the whole area. They then have to trawl through pages of addresses and start phoning. Again, if they don't know specific street names of where they're looking, they waste a lot of time on the phone.
The vacancy co-ordinator scheme was scrapped in our area as it was felt that the website worked so well (I think most of the hits on it are from the childminders themselves!) As an ex-vacancy co-ordinator, parents often get given my telephone number by other minders as they think I know everybody, but I'm not allowed to have access to new childminder contact details any more (data protection). So I sound like a complete plank as I know nothing about anything any more.
Parents get somewhat frustrated with the whole thing, and I know that some of them have ended up with choosing a nursery instead.
Oh Nick, what have you started!! One of my pet hates!
