What is the GMAT? What does it measure? How reliable is it? How is it biased?
The GMAT (Graduate Management Admission Test) is a standardized exam used primarily for admissions to MBA and other business-related graduate programs. It evaluates analytical, quantitative, verbal, and reasoning skills considered important for business school success.
✅ What Does the GMAT Measure?
The GMAT assesses skills across four key sections:
- Verbal Reasoning – tests reading comprehension, critical reasoning, and sentence correction.
- Quantitative Reasoning – evaluates problem-solving ability using arithmetic, algebra, and geometry.
- Integrated Reasoning – measures ability to evaluate data presented in multiple formats (graphs, tables, etc.) and synthesize information.
- Analytical Writing Assessment (AWA) – requires analysis of an argument and tests clarity of thought and writing ability.
Scores range from 200 to 800 for the overall score (based on Quantitative and Verbal), 1 to 8 for Integrated Reasoning, and 0 to 6 for AWA.
🔍 How Reliable Is the GMAT?
The GMAT is widely considered a reliable and statistically valid measure of skills relevant to business school performance.
- Standardized scoring – Ensures comparability across test dates and candidates.
- Computer-adaptive testing – The Verbal and Quant sections adapt to the test-taker’s ability, enhancing accuracy.
However, performance can be influenced by preparation resources, familiarity with adaptive testing, and test-day conditions.
⚖️ How Is the GMAT Biased?
While designed to be impartial, the GMAT exhibits several types of bias, often tied to structural inequities:
Socioeconomic Bias
- Students with financial resources can afford coaching, prep materials, and multiple attempts.
- Cost of the exam and score reporting may deter economically disadvantaged applicants.
Language and Cultural Bias
- The Verbal section may present challenges for non-native English speakers or those unfamiliar with business-oriented vocabulary or writing styles.
Predictive Validity Limitations
- While the GMAT is a moderate predictor of first-year MBA performance, it does not strongly correlate with long-term academic or professional success.
Accessibility and Accommodations
- Candidates with learning disabilities or who lack knowledge about requesting accommodations may be unfairly disadvantaged.
