SAT Score Predictorの包括的な教育ガイドを準備中です。ステップバイステップの解説、数式、実例、専門家のヒントをお届けしますので、もうしばらくお待ちください。
The SAT Score Predictor estimates your likely SAT total score based on PSAT/NMSQT results, practice test performance, and preparation level. The SAT, administered by the College Board, is the most widely taken college admissions exam in the United States, with approximately 1.9 million test-takers annually. The exam consists of two sections: Evidence-Based Reading and Writing (EBRW, 200-800) and Math (200-800), yielding a total score range of 400-1600. Since 2024, the SAT is administered digitally with an adaptive format, adjusting question difficulty based on performance within modules. This predictor uses established correlations between PSAT scores, study hours, and actual SAT outcomes to generate a realistic score range.
SAT Total = Evidence-Based Reading & Writing (200-800) + Math (200-800); Score Range: 400-1600
- 1Enter your most recent PSAT/NMSQT scores (EBRW and Math, each 160-760) or SAT practice test scores.
- 2PSAT scores are scaled upward to the SAT range — PSAT scores correlate highly (r=0.92) with SAT scores, typically predicting within 50 points.
- 3Indicate your planned preparation intensity: hours per week and weeks of study.
- 4The predictor applies improvement factors based on research showing average gains of 60-100 points with 20+ hours of focused practice using official materials.
- 5Optional inputs include current GPA, AP/Honors courseload, and previous test history for refined predictions.
- 6The result displays a predicted score with a confidence range (+/- 30-50 points) to account for test-day variability.
- 7Percentile rankings, college competitiveness tiers, and National Merit qualification thresholds are shown alongside the prediction.
PSAT total: 1100. Historical correlation suggests SAT scores are typically 40-80 points above PSAT. With 40 hours of structured prep, an additional 50-point gain is expected. Predicted: 1100 + 60 (PSAT→SAT) + 50 (prep) = ~1190. This is approximately the 72nd percentile.
Practice total: 1420. With 80 hours of intensive prep targeting Math (the weaker section), improvement of 40-80 points is realistic at high score ranges where marginal gains are harder. A 1480 is approximately the 99th percentile and competitive for Ivy League admissions.
Practice total: 940. Only 6 hours of prep provides minimal improvement (20-30 points). A 970 is near the 42nd percentile. This student would benefit significantly from more preparation time — even doubling study hours could add 60-80 points.
Targeted math preparation with 72 hours of study can yield a 50-80 point improvement on the weaker section. If Math rises from 620 to 690 and EBRW improves slightly to 680, the total reaches 1370. A 90-point improvement on retake is at the higher end of typical gains but achievable with focused effort.

Test-Optional and Test-Blind Admissions
Over 1,800 colleges are now test-optional (SAT/ACT not required), and a few (including the University of California system) are test-blind (scores not considered at all). However, submitting strong scores can still help at test-optional schools, and many merit scholarships still require them. The trend is evolving — check each school's current policy.
SAT Accommodations
Students with documented disabilities can receive extended time (50% or 100% extra), extra breaks, screen readers, or alternative testing locations. The College Board's SSD (Services for Students with Disabilities) process requires school-based documentation. Scores earned with accommodations are not flagged to colleges and are treated identically.
International Students
The Digital SAT is administered internationally at Prometric test centers. International students whose first language is not English typically find the EBRW section more challenging and may benefit from intensive reading practice. The SAT does not have a separate English proficiency requirement — international students usually also submit TOEFL or IELTS scores separately.
| SAT Total | Percentile | ACT Equivalent | Competitiveness |
|---|---|---|---|
| 1550-1600 | 99th+ | 35-36 | Ivy League, Stanford, MIT, Caltech |
| 1490-1540 | 98th-99th | 33-34 | Top 10-20 national universities |
| 1400-1480 | 94th-97th | 31-32 | Top 25-50 universities, strong merit aid |
| 1300-1390 | 85th-93rd | 28-30 | Competitive state flagships |
| 1200-1290 | 74th-84th | 25-27 | Most four-year universities |
| 1100-1190 | 58th-73rd | 22-24 | Many state universities |
| 1000-1090 | 40th-57th | 19-21 | National average range |
| 900-990 | 23rd-39th | 17-18 | Less selective institutions |
| 400-890 | 1st-22nd | 1-16 | Community colleges, open-admission schools |
What is a good SAT score?
The national average is approximately 1050. A 1200+ is above average (74th percentile), 1400+ is competitive for top-50 universities (94th percentile), and 1500+ is exceptional (99th percentile). Check the middle-50% score range for your target schools.
How is the Digital SAT different from the old paper SAT?
Since March 2024, the SAT is fully digital and uses a multistage adaptive format. The test is shorter (2 hours 14 minutes vs. 3 hours), each section has two modules, and the difficulty of the second module adjusts based on your first-module performance. Calculators are allowed on all math questions.
How many times can I take the SAT?
There is no limit, but most students take it 2-3 times. Score Choice allows you to send only your best scores to colleges, and many schools superscore (take the highest EBRW and Math from different sittings). Diminishing returns set in after 3 attempts.
What is superscoring?
Superscoring combines your highest EBRW score from any test date with your highest Math score from any test date. Over 90% of colleges that accept the SAT will superscore. For example, if you scored 700 EBRW / 650 Math in March and 680 EBRW / 720 Math in October, your superscore would be 700 + 720 = 1420.
Should I take the SAT or ACT?
Take a full-length practice test of each under timed conditions and compare. If scores are similar, consider that the SAT has no Science section and allows more time per question, while the ACT covers more ground faster. All US colleges accept both equally.
What is the National Merit cutoff?
National Merit Semifinalist qualifying scores are based on the PSAT Selection Index and vary by state, typically ranging from 209 (lower-scoring states) to 223 (high-scoring states like New Jersey and Massachusetts). Approximately 16,000 students qualify as Semifinalists annually from 1.5 million entrants.

ご存知でしたか？
The SAT was originally called the 'Scholastic Aptitude Test' when it debuted in 1926. It was renamed the 'Scholastic Assessment Test' in 1993, and since 1997, the College Board says 'SAT' does not stand for anything — it is simply the name of the exam.
