The 0.13% Filter
In September 2021, the Justice A.K. Rajan Committee published a census of over 30,000 medical admissions in Tamil Nadu across a decade. In the year before NEET, government school students secured 14.4% of seats. Four years later, that figure collapsed to 0.13%. This is how a single examination re-engineered medical admissions.
In 2016, when the Supreme Court of India mandated that all medical admissions across the country must occur through a single national test, the legal rationale was unequivocal: NEET would eliminate commercial capitation fees, establish a uniform national merit standard, and provide every Indian student with a fair and equal chance to enter medicine.
Five years later, the Government of Tamil Nadu commissioned retired High Court Judge A.K. Rajan to lead an expert committee to examine what actually happened to the students who entered medical colleges after the test was made compulsory.
The committee did not conduct an informal opinion survey. They examined the complete, verified admission records of more than 30,000 students admitted to MBBS programs over a ten-year span (2010–11 to 2020–21).
The data revealed a transformation so acute that it challenged the fundamental definition of academic merit.
In 2016–17, under the state’s high school board system, 14.8% of admitted students came from Tamil-medium schooling, and first-generation learners accounted for a quarter of the class. By 2020–21, Tamil-medium representation had collapsed to 1.7%. Students from state government schools — where the poorest rural families send their children — secured just 0.13% of open medical seats.
Meanwhile, 99.0% of all admitted students had attended commercial coaching institutes, and 71.4% were repeaters who had deferred college for one to four years to prepare.
This article examines what the Rajan Committee measured, how a single multiple-choice test inverted decades of public education policy, and why the findings ignited a constitutional debate that remains unresolved.

Baseline under state board
Severe 88% contraction
Down from 24.9% pre-NEET
Data from Justice A.K. Rajan Committee Report (September 2021). Evaluates complete census of admitted MBBS candidates across Tamil Nadu.
The census: 30,000 admission records over a decade
Most education debates in India rely on anecdotal reporting or small convenience samples. The Justice A.K. Rajan Committee report is distinct because it is an exhaustive empirical census.
The committee obtained the master admission registers from the Directorate of Medical Education (DME) in Tamil Nadu. The dataset encompassed two distinct historical periods: 1. The Pre-NEET Baseline (2010–11 to 2016–17): Admissions governed strictly by normalized Class 12 Plus Two higher secondary board marks, allowing students to transition directly from school to medical college without a gap year. 2. The Post-NEET Era (2017–18 to 2020–21): Admissions governed strictly by NEET-UG All India Ranks.
Because the committee evaluated the full universe of admitted candidates rather than a statistical projection, there is no margin of sampling error in the findings. The shifts recorded in the report represent the actual demographic composition of Tamil Nadu's medical classrooms.
The rise of the professional repeater: 71.4%
The most decisive structural change documented by the Rajan Committee was the near-total extinction of the fresh high school applicant.
In the pre-NEET period, medical entrance was synchronized with high school completion: over 75% of admitted candidates were first-time applicants who took their seats immediately after passing Class 12.
Under NEET, that dynamic reversed completely: - By 2020–21, 71.4% of all admitted candidates were "repeaters" (students who had spent one, two, three, or four drop years studying exclusively for NEET). - Only 28.6% of admitted candidates were fresh Class 12 students.
The explanation is structural: a fresh Class 12 student must study English, regional languages, descriptive physics, chemistry laboratory practicals, and board curricula simultaneously. A repeater has no school attendance requirements, no laboratory exams, and no board tests; they spend 14 to 16 hours a day solely memorizing multiple-choice algorithms and practicing negative-marking heuristics.
Because NEET offers unlimited repeat attempts and has no upper age ceiling, high school seniors are forced to compete against candidates who have completed the same syllabus three or four times. In this environment, fresh Class 12 completion is no longer an entry qualification; it is merely the preliminary registration for an multi-year drop cycle.
The 99% barrier: The mandatory commercial tax
Before NEET, private coaching was a supplementary advantage utilized by roughly 10% to 15% of aspirants.
The Rajan Committee surveyed the 2020–21 admitted cohort and discovered that 99.0% of admitted candidates had undergone commercial private coaching. Non-coached students accounted for exactly 1.0% of admissions across the state.
The economic implications were immediate. The committee estimated that the average cost of residential or corporate coaching in Tamil Nadu and national centers ranged from ₹1.5 lakh to ₹4.5 lakh per year. For a student requiring two repeat attempts, the cumulative preparatory investment routinely exceeded ₹5 lakh to ₹9 lakh.
NEET had been introduced by judicial mandate to eliminate corrupt private medical college capitation fees (which routinely reached ₹50 lakh to ₹1 crore). The data demonstrated that while NEET curbed illegal donation seats, it replaced capitation fees with an obligatory, front-loaded coaching fee barrier that systematically filtered out families who could not afford to sustain multiple years of commercial test-prep.
The demographic collapse: Vernacular medium and government schools
When admission depends on purchasing multi-year coaching in an NCERT-calibrated curriculum, students from marginalized social backgrounds are systematically squeezed out.
The committee documented severe demographic shifts between 2016 and 2020: - Medium of Instruction: Admitted students who completed their schooling in Tamil fell from 14.8% in 2016–17 to 1.7% in 2020–21. English-medium candidates expanded from 85.2% to 98.3%. - Government School Entrants: Students educated in state government schools — predominantly from lower-income, rural, and Dalit communities — accounted for an average of 1.2% to 1.4% of admissions pre-NEET. In 2020–21, out of more than 3,000 government medical seats, only 6 students from government schools gained admission without horizontal reservation — a representation rate of 0.13%. - Parental Income: Admitted candidates from families earning less than ₹2.5 lakh annually declined from 47.4% to 41.1%, while students from families earning above ₹2.5 lakh rose to 58.9%. - First-Generation Learners: Candidates who were the first in their families to attend higher education dropped from 24.9% before NEET to 14.4% in 2020.
The data proved that NEET's uniform testing format did not create a uniform playing field. By detaching medical entry from high school performance and tethering it to an expensive coaching industry calibrated in English and CBSE frameworks, the system concentrated admissions among urban, affluent repeaters.
The policy aftermath: The 7.5% horizontal reservation
The Rajan Committee’s empirical revelations made it politically impossible for the state to maintain the status quo.
Even before the full report was tabled, preliminary admissions data showing that only a handful of government school students were entering medical college forced the Tamil Nadu Legislative Assembly to pass landmark legislation: the 7.5% Horizontal Reservation Act (2020).
This law carved out an explicit 7.5% quota across all government and private medical college seats strictly for students who had studied in government schools from Class 6 to Class 12 and cleared NEET. In its first year of implementation, the 7.5% reservation restored over 400 government school students to medical college lecture halls — proving that only affirmative structural carving could bypass the commercial coaching barrier.
Concurrently, the Tamil Nadu Assembly passed a bill seeking complete exemption from NEET, proposing a return to high school Plus Two marks. While that bill remains stalled in constitutional and presidential assent challenges, the empirical findings of the Rajan Committee established the definitive benchmark used in academic and policy discussions nationwide.
What this data doesn't prove
That NEET questions are academically flawed. The Rajan Committee’s analysis did not claim that NEET’s physics, chemistry, or biology questions are incorrect. The critique is sociological and structural: an examination can be psychometrically sound while functioning as a devastating socioeconomic filter when access to the training required to answer it is commercialized.
That board marks were completely free of flaws. Before NEET, critics noted that state board examinations encouraged rote learning and that different state boards lacked national comparability. Returning to raw high school marks without standardized normalization carries its own administrative challenges.
That coaching students make worse doctors. The study evaluated admission demographics; it did not track medical students through their five-year MBBS coursework, clinical internships, or postgraduate residency performance. Whether coached repeaters perform better or worse as practicing hospital clinicians remains unmeasured.
That Tamil Nadu’s numbers are identical in every state. States like Rajasthan, Bihar, and Uttar Pradesh have longer historical traditions of sending school graduates into national competitive entrances (AIPMT, IIT-JEE). Tamil Nadu’s stark demographic drop was intensified because its school curriculum had historically diverged from the central CBSE syllabus.
