Why Testing Terminology Matters
Standardized tests have their own vocabulary — and if you don't know what words like superscore, concordance, or test-optional actually mean, navigating the college admissions process becomes unnecessarily confusing. Misreading a school's testing policy could mean submitting scores that don't help you, or skipping a submission that would have strengthened your application.
This glossary covers the most important terms students and families encounter when dealing with standardized testing in college admissions. Each definition is written in plain language so you can read a school's admissions page and know exactly what it's telling you. For context on how test scores fit into the broader application, see how admissions offices read your application.
Standardized Test
An exam administered and scored under consistent conditions nationwide, allowing colleges to compare applicants from different schools and grading systems. The SAT and ACT are the most widely used examples in US college admissions.
Test-Optional
A policy under which submitting SAT or ACT scores is not required for admission. Applicants may choose whether to include scores, and applications without them are still considered complete.
Test-Blind
A stricter policy where a college will not consider standardized test scores even if an applicant submits them. Unlike test-optional schools, test-blind institutions exclude scores from the review process entirely.
Superscore
A composite score calculated by combining a student's highest section scores from multiple test dates. For example, if a college superscores the SAT, it takes your best Math score and your best Reading and Writing score regardless of which test date each came from.
Percentile Rank
A figure showing what percentage of test-takers scored at or below a given score. A 75th percentile score means the student scored higher than 75% of the comparison group — it does not mean the student answered 75% of questions correctly.
Concordance Table
An officially published crosswalk that translates scores between the SAT and ACT onto a comparable scale. Colleges use concordance tables to evaluate applicants who submitted different tests on equal footing.
Middle 50%
The range of test scores between the 25th and 75th percentile of a college's enrolled class. It is the most practical benchmark for gauging whether your scores are competitive at a given school.
Score Choice
A feature offered by the College Board that allows SAT test-takers to select which test-date scores to send to colleges. Not all colleges honor score choice — some require applicants to submit all scores from every test date.
Writing Section
An optional or required essay component offered as part of either the SAT or ACT. Some colleges have required it as part of their application review, though many have made it optional or eliminated the requirement.
Scaled Score
The final score reported after raw test results are adjusted through a process called equating, which accounts for slight differences in difficulty across test forms. Scaled scores allow fair comparisons across different test dates.
Subject Tests
Formerly offered by the College Board, these were standardized exams in specific academic subjects (such as Math Level 2 or US History). The SAT Subject Tests were discontinued in 2021, though AP exam scores sometimes serve a similar signaling purpose.
Score Report
The official document sent by the testing agency directly to colleges on a student's behalf. Colleges typically require official score reports — scores self-reported on an application are usually used for initial review only.
Key Policies and Score Concepts Explained
Beyond the definitions themselves, it helps to understand how these terms interact during the application cycle.

Score Submission Strategies
Test-optional does not mean test-blind — colleges that are test-optional will still consider scores if you submit them, so it matters whether your scores are likely to strengthen or weaken your application relative to other parts of your file. When in doubt, research the middle 50% score range a school publishes for its admitted class, which represents the 25th to 75th percentile of enrolled students.
Superscoring can meaningfully change your strategy. If a school superscores the SAT — combining your highest Math from one test date with your highest Evidence-Based Reading and Writing from another — it can be worth testing more than once even if your composite score doesn't rise dramatically.
Understanding Concordance and Score Comparisons
Because the SAT and ACT use different scales, colleges that accept both rely on concordance tables — officially maintained crosswalks between the two tests — to compare applicants fairly. If you took both tests, it's worth comparing your scores using these tables to see which translates more favorably before deciding what to submit.
Planning your testing schedule around these considerations is easiest when you map it to your broader application timeline. The college application timeline can help you identify the best windows to test and retake exams without crowding your senior-year workload. You may also find the senior year preparation checklist useful for keeping testing milestones alongside other deadlines.
