How Many Students Appeared for CAT 2023? IIM Lucknow Data

CAT 2023 was the first year the cohort stopped behaving like a pandemic dataset. Approximately 2.88 lakh candidates appeared for the exam out of 3.28 lakh registered - a record jump of about 66,000 test-takers over CAT 2022 and the sharpest year-on-year cohort increase in recent CAT history. Conducted by IIM Lucknow on 26 November 2023, this was the exam where attendance rates recovered to 88 percent, hundred-percentile counts rose to 14, and the cohort signal finally looked like a steady-state management-aspirant population rather than a pandemic-disrupted one. For any CAT 2026 aspirant, CAT 2023 is the cleanest reference year for understanding what normal CAT competition looks like.

Why CAT 2023 Is the Cleanest Post-Pandemic Reference Year

The CAT 2023 appearance count matters more than it might look on paper. It is the first CAT cycle in the current era where every major cohort signal - registrations, attendance, and top-of-distribution density - moved in the same direction at once. Earlier years carried pandemic fingerprints. Later years, like CAT 2025, saw a slight cohort contraction. CAT 2023 sits exactly in the middle as the reference year that behaves like normal CAT.

Three specific reasons make CAT 2023 the cleanest data point for CAT 2026 planning:

• First fully normalised cohort. Pandemic-era attrition had ended. Candidates who registered actually appeared at industry-norm rates, with 88 percent attendance versus the 83.34 percent CAT 2021 floor.
• Record year-on-year growth. The 66,000-candidate jump over CAT 2022 is the largest in recent CAT history and set the cohort density template that CAT 2024 and CAT 2025 inherited.
• Stable paper structure. CAT 2023 was the third and final year of the 66-question template, so the CAT 2023 exam pattern was fully settled and cohort behaviour was not distorted by structural surprise.

The CAT 2023 Registered vs Appeared Split

The most useful way to read CAT 2023 cohort data is to see the 3.28 lakh registered figure next to the 2.88 lakh appeared figure. The roughly 40,000 candidate drop-off is the closest to pre-pandemic attrition the CAT cycle has recorded since 2019. The attendance ring below visualises the 88 percent completion rate and the gap at one glance:

Four observations follow directly from this attendance pattern. First, registered candidates in 2023 were genuinely serious about appearing - the uncertainty that drove pandemic-era drop-off had ended. Second, the drop-off that remained was structural, reflecting candidates who change career plans between August registration and November exam. Third, the 88 percent rate became the baseline for CAT 2024 and CAT 2025 attendance calculations. Fourth, the pre-pandemic CAT attrition norm of 10 to 12 percent was fully restored in CAT 2023, which is why the cohort is treated as the first fully normalised year in recent memory.

The Record +66,000 Jump from CAT 2022 to CAT 2023

The single most striking CAT 2023 statistic is the year-on-year cohort increase. CAT 2022 had seen approximately 2.22 lakh candidates appear. CAT 2023 saw approximately 2.88 lakh appear. The difference is an extra 66,000 candidates in a single year, which is the largest one-year jump in the current CAT era and among the largest in CAT history overall. The milestone card below visualises the magnitude:

Three factors stacked to produce this record jump. The first was deferred-cohort convergence: candidates who had skipped CAT 2020, CAT 2021, or CAT 2022 because of pandemic uncertainty decided 2023 was the right attempt year. The second was a broader post-pandemic management-career renewal wave, with engineering and commerce graduates rethinking corporate paths and targeting MBA programmes in unusually high numbers. The third was test-centre expansion from 156 cities in CAT 2021 to 167 cities in CAT 2023, which lowered the logistical bar for smaller-city candidates.

For CAT 2026 aspirants, the 2023 jump is a reminder that cohort size is not a simple linear extension of any single prior year. Large cohorts can materialise when deferred demand meets favourable conditions, and the 2026 cohort will settle at whatever level the combination of deferred candidates, first-time aspirants, and macroeconomic signals produces. Anchor your expectations on the CAT 2023 scale as the floor, with upside surprise possible.

The 14 CAT 2023 Hundred-Percentilers

The top of the CAT 2023 distribution tightened in parallel with the cohort expansion. Fourteen candidates scored a perfect 100 percentile in CAT 2023, up from 11 in CAT 2022 and 9 in CAT 2021. The educational and gender breakdown of the 14 toppers is worth recording because it previews the trajectory that continued into CAT 2024 and CAT 2025:

CAT 2023 Percentile Distribution at the Top

Understanding how the CAT 2023 cohort stacked up at the top of the distribution tells you how competitive the percentile bands actually were. The cascade below compiles the top four percentile tiers with scorer counts, based on IIM Lucknow official data and post-result analyses:

Two observations matter here. First, the top three tiers in CAT 2023 are statistically tiny - 72 candidates across 100, 99.99, and 99.98 percentile combined, out of the 2.88 lakh who appeared. Second, the 99 percentile band - which is what most serious CAT aspirants actually target - housed roughly 2,880 candidates, giving a concrete sense of how crowded the top 1 percent of the cohort was. For CAT 2026 aspirants, these numbers show that the 99 percentile mark is competitive but genuinely reachable with a disciplined preparation roadmap.

Gender and Demographic Breakdown of CAT 2023 Test-Takers

Among the 2.88 lakh candidates who appeared for CAT 2023, the demographic split showed modest movement on gender compared to earlier years. IIM Lucknow's official data, cross-referenced with coaching-institute analyses, gives the full picture across three dimensions:

• Gender: 64 percent male, 36 percent female, 5 transgender candidates - slightly more balanced than CAT 2021's 65-35 split.
• Educational background: roughly 68 percent engineering graduates, 32 percent from non-engineering streams such as commerce, arts, and science - in line with the broader Indian undergraduate intake pattern.
• Top-of-distribution diversity: 11 of 14 hundred-percentilers from engineering, though non-engineering representation has been trending upward since.

The gender split is slowly becoming more balanced year on year, though the change is incremental. CAT 2023's 36 percent female participation was 1 percentage point higher than CAT 2021, and the five transgender candidates represented an uptick from the two in CAT 2021. The top of the distribution remains a challenge area for gender balance, with all 14 CAT 2023 hundred-percentilers male and only 1 female candidate reaching 99.99 percentile. Aspirants from under-represented backgrounds should still plan with the same preparation intensity as their counterparts - the paper is genuinely cohort-neutral on content, and strategy matters more than demography at the top.

Where CAT 2023 Sits in the Five-Year Arc

The clearest way to see CAT 2023's role as the recovery inflection year is to place it next to every cohort year on a single timeline. The arc below shows the five-year CAT appearance trajectory with CAT 2023 marked as the inflection point:

Three arc-level patterns matter. The first is the sharp climb from CAT 2021 to CAT 2023, where appearance counts grew by 50 percent in just two years as pandemic normalisation completed. The second is the plateau at CAT 2023 to CAT 2024, where the cohort settled into its post-pandemic steady state. The third is the unexpected contraction at CAT 2025 back to 2.58 lakh, which is still above CAT 2023 levels but represents the first year-on-year decline in the cycle - detailed in the CAT 2025 cohort analysis.

What the CAT 2023 Cohort Signals for CAT 2026 Preparation

Translating CAT 2023 cohort data into CAT 2026 preparation signals is where the numbers become useful. Five specific lessons emerge when you read the 2023 baseline alongside the broader five-year arc, and each one maps to a concrete adjustment in how you plan the next seven months:

1. Anchor cohort expectations at 2.7-2.9 lakh. CAT 2023 confirmed this as the normalised range. Expect similar density in CAT 2026 rather than CAT 2021-era numbers.
2. Attendance is structurally high now. 88 percent in 2023 became the new floor. Registered candidates are serious about showing up, which means the real competition is tighter than raw registration numbers suggest.
3. The top band is fixed in relative size. 14 candidates at 100 percentile out of 2.88 lakh gives a rate of about 1 in 20,571. That ratio has held in subsequent years, so plan your 99+ percentile target around this structural tightness.
4. Non-engineering representation is rising. CAT 2023 had 3 non-engineer 100-percentilers, CAT 2025 had 9. Plan around a paper that increasingly rewards reading depth and cross-disciplinary thinking.
5. Year-on-year jumps are possible. CAT 2023 added 66,000 candidates in a single year. If the CAT 2026 cohort surprises on the upside, you want your CAT 2026 preparation plan robust enough to absorb denser competition without recalibration.

Most CAT aspirants do not have a data problem. They have a reference-point problem. The right baseline year turns cohort statistics into useful preparation input, and for CAT 2026 planning that baseline is CAT 2023. Clarity first. Then effort.
