In a traditional competitive test, every candidate answers the same set of questions. Test scores are based largely on the number of correct answers. Most coaching centres therefore prioritise testcracking tactics over conceptual understanding, or critical thinking.
Adaptive testing is a dynamic form of assessment which uses the Item Response Theory (IRT). This means that the questions in the test are not the same for all students. A question bank is prepared with questions of varying difficulty covering all the items in the syllabus. The test normally begins with a question of medium difficulty. If it is answered correctly, the computer selects a more difficult question from the question bank using the scientifically established psychometric models.
If incorrect, an easier question is presented. After each answer, the computer recalculates the candidate’s estimated ability. The test ends when a predefined level of assessment is reached or the set number of items as per syllabus are tested. The goal is to assess the ability of the candidate more precisely by asking fewer but bettertargeted questions. The result is that two candidates may see different questions but are assessed on the same underlying scale.
Adaptive testing builds fairness into the test design itself rather than correcting for variations subsequently. Since the next question depends on the previous answer, a student who is not conceptually sound cannot answer the progressively highdifficulty questions, which have higher weightage. Global testing agencies have been using computerised adaptive testing for admissions to premier institutions for over 25 years.
In the Indian constitutional context, ‘equality of opportunity’ is often interpreted as everyone getting the same question paper. Therefore, a move towards adaptive testing may face Article 14 challenges (Right to Equality) in Indian courts, if the normalisation process is not transparent. Algorithm opacity could invite bias suits under equity mandates. However, this can be mitigated through disclosures and equity audits.
In India, where a single rank can make or mar a rewarding career, it may be difficult to convince a parent how a student who solved 20 difficult questions correctly has scored higher than another student who solved 50 easy ones. Ensuring lagfree technical infrastructure in tier3 cities is key, as any technical glitch during the test could be seen as maladministration in a court of law. Without clear documentation and grievance mechanisms, litigation risks rise. Data centre reliability, proctoring invigilation systems, and incident handling must be far stronger than today’s baseline.
Transitioning from the traditional linear test to adaptive tests requires building large, calibrated item question banks, pretesting questions without the possibility of leakage, and ensuring strict syllabus coverage. There are also trust challenges: candidates must believe that different questions can still be fair, and testing agencies must be prepared to defend this scientifically and legally. International experience from GRE and GMAT shows that transparency, technical documentation, and phased rollouts are essential for acceptance.

Which of the following is the primary reason adaptive testing is suggested as a “better and less stressful assessment” compared to traditional competitive tests?
A. It allows students to skip questions they find difficult.
B. It reduces the overall syllabus tested in the examination.
C. It evaluates a candidate’s ability more precisely using fewer, well-targeted questions.
D. It ensures all candidates face questions of identical difficulty levels.
Correct Answer: C
The author suggests that adaptive testing may face legal challenges under Article 14 of the Constitution mainly because:
A. Adaptive testing relies on computer-based systems rather than pen-and-paper tests.
B. Coaching centres may not be able to prepare students effectively for such tests.
C. Courts do not recognise scientific assessment models like Item Response Theory.
D. Equality of opportunity is often interpreted as candidates receiving the same question paper.
Correct Answer: D
Which of the following assumptions underlies the concern that parents may find adaptive testing difficult to accept?
A. Parents equate fairness with the number of questions answered correctly rather than difficulty level.
B. Parents generally distrust all forms of computer-based examinations.
C. Parents believe that easy questions should always carry equal weight as difficult ones.
D. Parents assume that traditional examinations are free from any form of bias.
Correct Answer: A
According to the passage, which of the following would most directly help reduce litigation risks associated with adaptive testing in India?
A. Establishing transparent normalisation processes and robust grievance redressal mechanisms.
B. Increasing the total number of questions attempted by each candidate.
C. Limiting adaptive testing only to urban centres with advanced infrastructure.
D. Conducting adaptive tests only after abolishing rank-based admissions.
Correct Answer: A
The reference to GRE and GMAT in the passage primarily serves to:
A. Prove that adaptive testing always produces better academic outcomes.
B. Illustrate that international experience supports phased, transparent implementation of adaptive tests.
C. Argue that Indian testing agencies should fully replicate foreign examination models.
D. Suggest that adaptive testing is suitable only for postgraduate-level examinations.
Correct Answer: B
