Graduating from the orphanage

Kids go through the 9th grade in the typical Ukrainian orphanage; then they go on to a trade school for the 10th and 11th grade.  The supervision there is not the same as in the orphanage.  Yes, they get fed and have a roof over their head and even get a small stipend from the government.  But they have a lot of hard choices to make when sex, drugs, alcohol and crime are but a breath away.  Many graduates do not stay in school; many give in to the various temptations.  But can we blame them?   Even a well-parented 16 year old would have a hard time being thrust out on his own.  Or what about a well-parented 15 year old?  Or 14 year old?  Could your 13 year old make good choices if left to his own devices?  One of my Ukrainian sons would have graduated from the orphanage at 13 due to being moved up several grades in school.  I thought this was unusual.  But at least 3 of our hosted kids will graduate next year, two at age 14 and one at age 13.  They are much too young for the "freedom" of a trade school.  And it bothers me.
