I wish that students and parents could see what I see high school counselors doing at the conferences I've been attending lately. Since you can't be there, I'll tell you two things you should know.
First, your counselors aren't there for themselves–they are at those conferences for you. Sure, there's socializing and some fun weaved in for them (high-school-counselor-style fun, like College Trivial Pursuit). But they spend the bulk of their time attending sessions about upcoming changes to admissions policies and learning new ways to help students who need it most. I'm sure they'd all rather be at home with their families, but they are there. For you. And believe me, they're not required to be. In fact, a lot of them pay their own way because their schools can't afford to send them.
Second, if you want to see high school counselors get all riled up and defensive, propose something that could hurt their students. Like state budget cuts that eliminate scholarships. Or confusing application policies kids might not understand. Or just about anything that could take away college opportunities from you. Counselors are generally a mild and affable bunch. But they turn ferocious and rise up when people and policies get in the way of their students' path to college.
I'm not saying every counselor is perfect (no profession can claim all of its members are perfect). But keep my two observations in mind before you say, "Our counselors don't know anything," or "They don't do anything for us." They know and do more than you might think.
