What standardized tests does the College Board administer?

Expanded Question:
“Could you provide comprehensive information about the standardized tests administered by the College Board? I’m particularly interested in understanding the full range of assessments they offer, including well-known exams like the SAT and PSAT/NMSQT, as well as other programs such as the SAT Subject Tests (even though I know they’re being phased out), the Advanced Placement (AP) Program exams, and any pre-AP offerings. I’d like to know the purpose, typical audience, and format for each major test they administer.”

The College Board administers the following standardized tests:

1. SAT: A college admissions assessment measuring evidence-based Reading and Writing, and Mathematical Reasoning skills.
2. PSAT/NMSQT (Preliminary SAT/National Merit Scholarship Qualifying Test): A practice SAT for 10th/11th graders, also used to qualify for National Merit Scholarships.
3. PSAT 10: Similar to PSAT/NMSQT but taken exclusively by 10th graders, without National Merit qualification.
4. AP Exams (Advanced Placement): Subject-specific tests for high school students seeking college credit or placement, covering disciplines like Calculus, Biology, History, and more.
5. CLEP (College-Level Examination Program): Tests granting college credit for demonstrating knowledge of introductory college subjects, regardless of prior coursework.
6. ACCUPLACER: A suite of placement exams used by colleges to assess student readiness in reading, writing, math, and English as a second language.
7. SAT Subject Tests: Discontinued in the U.S. in 2021 (some international administrations until 2023), these assessed knowledge in specific subjects like Biology, Literature, or World History.
8. ReadiStep: Discontinued in 2016, this middle school assessment evaluated readiness for rigorous high school coursework.
9. SAT 8/9: Discontinued, these versions of the PSAT targeted 8th and 9th graders as early readiness indicators.
10. SpringBoard: A standardized curriculum and assessment program for grades 6–12, focusing on college readiness in English, math, and STEM.
11. CSS Profile (College Scholarship Service Profile): A detailed financial aid application supplement required by many colleges, beyond the FAFSA.
