TestAS Score Explained: How the 0–200 Scale, Percentile Rank & Certificate Actually Work
What a "TestAS score of 120" actually means, how it's calculated, how it compares to the older paper-based standard score, and how universities use it to decide admissions — based directly on official g.a.s.t. scoring documentation.

Two Numbers on Every Certificate
Your TestAS certificate doesn't give you a single grade. Instead, results for both the Core Module and your Subject-Specific Module are each reported on two separate scales, plus a combined overall figure:
- TestAS Score (0–200): A standardised score for the digital TestAS. The average range sits between 50 and 150, split into a lower-average and upper-average half at the 100 mark. Anything above 150 is above average, and the top roughly 2% of all test takers receive the maximum score of 200.
- Percentile Rank (1–100): Tells you where you stand relative to everyone else who has ever taken the test. A percentile rank of 60 means 60% of all test takers scored the same or lower than you — and 40% scored higher.
- Overall Score (0–400): The Core Module score and Subject Module score combined into a single overall figure shown on the certificate.
Because the percentile rank is calculated across every test date and location ever administered, your ranking reflects the entire historical pool of test takers — not just people who sat the exam on your specific date.

🏛️ How German Universities Use TestAS Scores
German universities integrate TestAS scores into their Selection Procedure (Auswahlverfahren) in three primary ways:
1. Abitur Grade Bonus (Bavarian Formula Conversion)
Universities convert TestAS standard scores into grade bonuses on the German 1.0–4.0 GPA scale. For example, a score of 115+ may grant a 0.2 to 0.5 bonus, turning an original GPA of 2.0 into a 1.5.
2. Hard Minimum Threshold Filter
Highly competitive faculties (e.g. Medicine at RWTH Aachen) mandate a minimum Percentile Rank of 80 or a Standard Score of 110 for application eligibility.
3. Tie-Breaker in Quota Admissions
When two international applicants share equal high school grades, the candidate with the higher TestAS Subject Module score receives preference.

❓ Frequently Asked Questions (FAQ)
Is a TestAS score of 100 considered good?
A score of 100 represents the exact global average (50th percentile). While acceptable for programs with basic requirements, competitive STEM and Medical degrees generally target scores of 110–120+.
Do TestAS score certificates expire?
No. TestAS score certificates carry lifetime validity and can be submitted for university applications at any time.
