I have thought about this all night since I saw your post.  I am curious how you want it answered.  I am trying to think of a way to word it.
All I can answer for is myself.  I have been doing title searches for almost 14 years.  I began the summer I graduated high school.  My ex-husband's mom worked for the Clerk's office and got me an interview with a title company.  In turn they trained me and I eventually became the department manager after 3 years.  I went to school and received my realtor's license as well.  I moved from PA to VA where I was shall I say re-trained by an attorney.  Va is so much different than PA.
Anyway, to make a long story short, I opened my own company 2 1/2 years ago because the guy I was working for went into receivership.  I have 3 abstractors at my company, myself, my business partner Susan and another on staff examiner.  Susan has 7 years exp. and my of staff guy, Manny, has 5.  I also do witness closings. 
So what makes someone qualified?  Well, experience, knowledge, maturity (may sound crazy, but true) and many other factors.  Those 19 year olds don't know what they are doing even though they think they do.  I know, I used to be one of them.
So did I answer your question and if not, what else can I tell you?????
