From a Veteran High School Specialist

I have just finished working with a around 700 high school seniors who had not yet made a college plan in their senior year.

Here's their profile: largely from under-represented groups (our target); primarily Hispanic followed by African American, Asian and a smattering of Anglo, most qualify for free or reduced lunch. A large percentage were born into a language other than English but have attended US schools for much of their lives.  Not many exempted from TSI based on TAKS, SAT or ACT scores,  very few make our cutoff scores on Accuplacer, quite a few can't read at college level or perform well with grammar but for some reason manage to pass the essay portion of the Accuplacer at a higher rate than one might expect.  As for math, even those who are in Pre-Calc or Trig have difficulty with the Accuplacer math assessment--why,you ask?  Well, they forget how to work fractions, percentages, decimals, and manipulate  algebraic properties AND they are so use to using a graphing calculator they've forgotten or never learned the math theories that are the foundation for the buttons they're pushing. (They're not really good about prepping for assessment either, even though they get plenty of information about how to do so.)  Most will need some financial assistance to attend college.  Most will be working while attending college.  Almost all will be living at home while attending college.  Their parents are very interested in their welfare and will attend sessions the college offers re enrolling in college, even if their child chooses not to attend.

I know this is just one segment of our 2009 class but, I would bet good money it comes close to the median description you'll be developing.
