We have run this article a boatload of times in the past, and based on questions and comments on our message boards it's time to bring it up again.
If you are going to be a senior next year (2015) and you haven't started this process you are behind.
If you plan to participate at an NCAA DI or DII school for athletics, then you need to get registered with the NCAA Eligibility Center (formerly known as the NCAA Clearinghouse). This is the "qualifying" process you must complete in order to compete - it takes a long time to get it all done. Their online service allows prospective student-athletes to register electronically.
If you are a sophomore (2016) then learn this process and become very familiar with it. Make sure you have your SAT and/or ACT scores sent to the NCAA Clearinghouse from your account on www.collegeboard.com .
Here's what you need to do. Go to NCAA Eligibility Center, and click on the "Prospective Student-Athletes" link. Follow the steps and you will have your own login for future reference.
Mail in an official transcript following the school year through your school's athletic department to the center so your status can be updated with core classes and grades. Check back routinely to your online account to see the status of your registration.
While you are at it, go to NCAA and check the requirements for NCAA DI and DII athletic participation. This site has all the GPA and SAT/ACT requirements that athletes need to achieve in order to play sports at the next level.
We keep a link to this article, and the SAT registration web site on "More" on our top gold menu bar. If you have any questions please feel free to email us and we'll do our best to steer you in the right direction. You can also ask questions on our forums for recruiting takes and how to navigate through the process.
Underclassmen/parents - learn this process in advance.
UPDATE: Check our 'more' link at the top of our site on the gold menu bar to get signed up to the NAIA Eligibility Center. The NAIA is a great place to receive an education and sports experience at the college level.
