I started leaving my oldest son at home alone for short periods at age 11. With my daughter it was 10.5 since she is more mature.

We have strict rules and so far they have shown to be very responsible. They always know where I'm going to be and I have the cell with me. I've also at times let the neighbor know so she can be a back up if necessary.

Everyone is different on this and while things have certainly changed over the years I personally believe that if I do not teach my children or start trusting them on small durations of time away from me, then they will not become responsible or trustworthy at an age where they MUST be.
