Here are a few things I can think of offhand. Hope it helps.
–**Be honest with the student upfront about any limitations you have on their higher education (finances, geography, anything else) so there are no last minute surprises on that front. This is probably the single most important thing a parent can do.
–Without being overbearing, be aware of deadlines and check that the student is on target (ex. to sign up for standardized tests, applications deadlines etc.). Also, suggest that they ask for teacher recommendations at the end of junior year (rather than the start of senior year).
–Visit colleges with your child if possible. Never opine on a school until your child has given his/her opinion first. And don’t visit any colleges you are not willing to send your child to (as they will inevitably fall in love with that school).
–Be available to proofread if asked. Proofread for grammar etc, never change the content of an essay. If you feel something is really terrible/inappropriate let your child know and let him/her fix it. The essays must be in the student’s voice and say what he/she wants to say.
–Help prepare the necessary financial aid forms.
–Check that your child applies to a good mix of schools – including reach, match, and safety schools that appear affordable and that he/she would be happy to attend. Often the hardest thing is to find a good safety school or two. If you have a good guidance counselor work with him/her on developing this list. There are also some good college guide books (ex. Fiske, Princeton Review) that can be helpful.
–Act as a positive, reassuring force. Do not let your child’s (or your own) self-worth get tied into what school they get into and what school they don’t get into. Be sure they understand there are many schools where they can have a great 4 years and get where they want to in life.
