general overall summation (sorry this got so long) I start by CAVEATING: this is based upon my experience ONLY, mostly as a parent, some as a user of services, some as a volunteer/worker in the college admit process, working at the HS level, private level, with many other students. Therefore they are MY OPINIONS only - take them or leave them. There is no "one size fits all" - but I have tried to list some of the general/larger categories of import.
Planning for all of this is the key. Start in Soph year, if possible. If not, make sure you start in Jr. year.
The first question any college coach will ask - "what are your grades and SAT/ACT scores?" Most colleges put grades first, then standardized testing, then any variety of other things from essays to community service, etc. Princeton Review will tell you what the college's order of priority is in their application process.
1. NCAA Eligibilty Center - register during Jr. year, but make sure to check it as early in the process as you can - make sure you have all of your core classes lined up. Get your SAT/ACT scores sent directly to them, get your transcripts in timely, etc. And make sure you sync these required Core classes up with whatever your HS requires for graduation, as you do need to graduate (duh).
3. Continue to work hard to keep grades as high as possible, improve grades, take increasingly more difficult classes up to and through senior year - DO NOT, repeat DO NOT slack off in senior year. Colleges will and do pull schollys if you blow Sr. year. Hopefully this will not apply to you, but if there are any extenuating circumstances as to why your grades may have tanked, please make sure you explain that in an essay in your application. Most colleges will give you an opportunity in their app. to do so. Believe me, they do listen/read/pay attention to this.
4. Take SATs and ACTs (with writing) - fall of Jr. year may be a little early (but DO take PSAT in Oct. of Jr. year - this is a shortened version of the SAT. That being said, it also has a much tougher curve, so your score will likely be lower than on an SAT.) Perhaps start with SAT or ACT in Dec, then rotate them again through the spring testing sessions and add in subject tests in the spring and early summer testing sessions. Take the subject tests in conjunction with your classes - i.e., take bio SAT when you are taking bio, take US history when you take this subject, etc. Also, it is must that you take the subject test for any subject where you are in an AP or IB class. Make sure you plan ahead to be able to take all tests more than once. Also, try to be completely DONE by June of Jr. year. It is very tough to come back in as a senior and take another test. However, that option is there if you must use it. It is a lot of testing (probably 6 sessions total), but just grit your teeth and do it. Here is where a strong athlete mentality will help you get through.
In fall of Jr year, you may not know where you will eventually end up in college, so do not limit yourself by closing any doors early on the testing side.
My thinking is that the Dec tests tend to be a little easier (yes, they vary the degree of difficulty in their testing patterns). The reason being that most seniors are done testing and most junior haven't started testing yet, so Dec. tends to be an easier test. The more difficult test is the March test, because that is when most Jrs. take their first SAT - caveat: this is JUST MY THOUGHT - based upon what I have seen from experience. See my prior email for more detail on subject testing, etc.
Don't send test scores until after you have them. That way you get to chose which to send. If ACT is better, pick the best one and send it. If SAT is better, send that one, but they will send all scores (for 09s). It will cost a little more to do it this way, but....
IF you get lucky and really NAIL your first standardized test, ask any coach at a college where you are interested IF they suggest you take another. Some may say "nope, you're done!" Lucky you! Some may say "yep, take another" (ugh)- most likely because the college wants to see consistency - i.e., that you can replicate the score, so that they know your "one time hit" isn't a fluke. Some coaches may not give you insight here, but you can call the college admissions officer and ask them. And the general rule of thumb is that you will/do improve in your second testing session. I believe statistics show that you do not improve (actually may even drop) after 3 testings, so you can use your own judgment here.
5. Sign up for a tutor for testing, if possible. It really can make a difference. They will/should teach you HOW to take the test - not really teaching subject matter of the test. Like anything else, there are good and bad ones out there. Some notable names include Ivy, Kaplan, Princeton Review - but there are others, so ask your friends who they may be using. If you cannot afford or otherwise decide not to do this, you still can and should invest in a practice test book - many are sold, just look in your local B&N or Borders, or whatever your bookstore may be.
6. Check all available website information. Princeton Review gives you a run down of the colleges- very thorough. Petersons is also very good, it seems to give more of a rating system from the students themselves. College Confidential is also a great resource, but remember that a lot of what is written on that site comes from the college applicants themselves - posting their thoughts and fears, etc. So, don't let it get you panicked when you read it - college seniors applying and awaiting application results can sound panicked (indeed, they probably all are - it is a reasonable thing to expect when they are awaiting such weighty decisions), and that tends to have a "stampede effect" on the reader. Oh, and I do believe that Admissions Officers do troll that site (whether this is a good or bad thing? I would not know). It is a helpful site, just as this site is so very helpful.
7. Fiske Guide is also a great resource book - there are others. This book will rate the colleges overall, and talk about general things like if you like college A, what other colleges should be considered as being similar, etc. There are other books out there too, but I do like Fiske best.
8. Common data set: eh, to me this one is just more relevant for knowing how many get in off of a wait list. Of course, if you are a recruited athlete, this has no import whatsoever to you. Not all schools prepare or publish a CDS. Not all schools call it a CDS - some have other names for them. And the information is historical for percentages of applicants, ranges, etc. So it is really only that - data for the general public. Interesting to read, but IMHO not too particular to a recruited athlete.
9. The app itself - make sure your student has developed a strong relationship with two teachers from his/her junior (particularly junior) year. He/she will need two (most colleges require two) recommendation letters from teachers other than their GC. Also, have them get to know their GC. GC's are excellent, but can appear not to be because they also tend to be overloaded with kids. Thus, the STUDENT should be the one to make sure this relationship gets developed. It will help when the GC goes to write his/her rec. letter for the student. There are many other things I could write here about the app. - like whether to use the Common App (if available), or not, but these are all individual decisions that you should make after doing a little research about the particular school. Ask the coach which their college prefers. Again, if you are a recruited athlete, your coach can/should/will tell you what his college/university needs/requires for the application process to be complete.
Oh, yeah, and try to get your student to start the essays over the summer of jr. sr. year, if possible. (Ugh again). DO NOT, repeat DO NOT write (or have anyone else write) these essays for them. Admissions officers are very good at what they do, and they can smell this a mile away. Yes, read them and perhaps discuss/brainstorm them with your student, but the idea/topic selected and their writing MUST come from your student alone!
10. GC v. Private College Counselor - eh, if you have the resources and the desire, the private can help you, but you can certainly do your own "homework" and do it yourself. IT JUST TAKES TIME and EFFORT to learn it all. Do not expect your GC at HS to do it all for you - they are great, but they can only spread their talents so far - Most GCs will have their own senior application packets and strategies, make sure you stay in touch with them and work through their system in their manner. That is the best way to get through the HS Admin portion of the Sr. college appl. process.
Ok, now all of you - feel free to pick apart, add, delete, etc. with your own input/experiences.
Having worked/volunteered/assisted/used both at the HS level and with private counselling (and with older sib. going through this entire process), these are my thoughts and experiences - again CAVEAT: these are MY thoughts and experiences. Take them for what they may be worth, or leave them to do your own thing - by no means what works for one works for all.
I know it sounds like a lot, but IMHO it is important. Whew. Long, sorry again.
If anyone has any other/more specific questions, please feel free to PM me. No guarantees I have all/any of the answers, but...
