College Admissions Tests: A Closer Look

To take these tests, you should be armed with more than a #2 pencil. Both major testing organizations offer lots of resources to help you prepare and study. Both also offer preparatory tests you can take early. Your local library and bookstore have books that can help you prepare. And if you don't do well the first time, don't panic — you can re-take the tests to try to raise your score.

The most common tests, with links to their Web sites:

• SAT Reasoning Test™. This test measures your ability to think and solve problems. Almost all colleges and universities accept the SAT as part of the admissions process. You can take the test in your junior and senior years.
• ACT. Like the SAT, the ACT is accepted by almost all colleges and universities. But instead of measuring how you think, the ACT measures what you have learned in school.
• SAT Subject Tests™. These tests measure your knowledge and skills in a variety of subjects. Some colleges use them for admissions and to help students choose the right courses. Some schools require them. At other schools, they are optional.
• AP® Tests. Short for Advanced Placement, AP tests give you the chance to earn college credit while still in high school. Many students take them after completing AP classes.
• CLEP® Tests. Short for College Level Examination Programs, these tests can help you earn college credit in many different subjects. They are often taken by home-schooled students, or people who are returning to college after being in the workforce.
• International® Baccalaureate Diploma Programme. This is a two-year program designed for college-bound high school students. It is accepted by hundreds of colleges and universities in the U.S. The course can help you earn college credit. Ask your guidance counselor if your school offers it.
