AISHE

#aishe
Definition

The All India Survey on Higher Education is a ministry-run annual census that collects data on enrolment, faculty, infrastructure, and fees across India's higher-education institutions.

Why it matters

AISHE is the only uniform data source that covers fees, faculty-student ratios, and enrolment at the institution level. It's the backbone of most cost-side claims on unbiasEd.

CGPA · Cumulative Grade Point Average

#cgpa
Definition

The weighted average of grade points across all completed semesters, typically on a 10-point scale in Indian engineering colleges. Universities convert it to an equivalent percentage using their own formula, which varies — an 8.0 CGPA is not always "80%".

Why it matters

Placement eligibility cutoffs at most engineering colleges are expressed as a minimum CGPA (commonly 6.0 or 7.0). A "90% placement" claim at a college with a 7.5 cutoff tells you nothing about students who fell below the line.

Common misconception

"CGPA × 10 = percentage." Only at some universities. Many (including IITs and several state universities) use their own conversion formula — check the transcript, not a rule of thumb.

C · methodology

Confidence tier

#confidence-tier
Definition

The three-level label unbiasEd attaches to every data point — Verified (independently audited or matches an official ranking cycle), High (from an official source but self-reported to it), Medium (reported by the college and not independently verified). Applied per data point, so a single college page can carry all three.

Why it matters

The whole site is built on source attribution. The tier tells you how much weight to put on a number before using it to compare colleges.

Common misconception

"Higher tier = better college." It doesn't. The tier describes trust in the number, not quality of the institution. An unverified "95% placement" claim and a verified "85%" are not directly comparable.

D · methodology

Data level · institute vs discipline vs branch

#data-level
Definition

Most rankings and surveys report numbers at the institute level (the whole college) or the discipline level (e.g. "Engineering at IIT Madras"). Branch-level data (e.g. CSE specifically) is rarely published by any official source, and when colleges publish it themselves it's almost never independently audited.

Why it matters

Presenting discipline-level or institute-level numbers as if they applied to one specific branch is the single most common trust failure in Indian college marketing — and the reason this site exists.

Common misconception

"IIT placement rate 95%" does not describe CSE, Mechanical, or any one branch. It's the institute-level number, pulled from NIRF. Branch-level rates can differ by 30+ percentage points.

GATE · Graduate Aptitude Test in Engineering

#gate
Definition

A national entrance exam for admission to postgraduate programmes (M.Tech, M.S., direct Ph.D.) at IITs, IISc, NITs, and other institutions, and for recruitment by several PSUs. Jointly conducted by the IITs and IISc on rotation. Scores are normalised across sessions and valid for three years.

Why it matters

GATE figures into the placement narrative at most engineering colleges — higher-studies conversions via GATE count toward NIRF's Graduation Outcomes parameter, which pulls up the "placement rate" number that colleges advertise.

JEE · Joint Entrance Examination

#jee
Definition

The national engineering entrance exam, run in two stages. JEE Main (conducted by NTA) is the gateway to NITs, IIITs, and GFTIs, and a qualifier for JEE Advanced (conducted by one of the IITs on rotation), which is the entrance for the IITs. Seat allocation happens via JoSAA counselling.

Why it matters

The JEE closing rank — the last rank admitted to a given branch in a given year — is the only publicly verifiable selectivity signal for an engineering college. It's also the cleanest way to compare branches across IITs / NITs.

Common misconception

"JEE Main rank 5000 gets you into any top NIT." Closing ranks are branch- and category-specific, and swing year to year based on seat matrix and student preferences. A single "rank" number doesn't map to a seat.

Median vs. average salary

#median-vs-average
Definition

The median is the middle salary in a sorted list of offers; the average is the arithmetic mean. A single ₹1 Cr offer can pull "average" package way up. Median doesn't move. For 99% of students, median is the relevant number.

Why it matters

NIRF reports median, not average; we follow suit. Headline "average" figures are the most common trick in college-marketing literature.

Common misconception

"Average package ₹12 LPA" sounds great until you learn that two students got ₹1 Cr each and everyone else got ₹4 LPA. Median would have said ₹4 LPA.

N · accreditation

NAAC

#naac
Definition

The National Assessment and Accreditation Council is an autonomous body under UGC that grades higher-education institutions on a letter scale (A++ / A+ / A / B++ / B+ / B / C). Accreditation cycles run roughly every five years.

Why it matters

Accreditation grade is a floor signal — an A+ institution has cleared a minimum bar on infrastructure, curriculum, governance and outcomes.

Common misconception

"A+" doesn't mean "top college." It's a quality floor, not a ranking.

NBA · National Board of Accreditation

#nba
Definition

An autonomous body under AICTE that accredits technical programmes — engineering, management, pharmacy — at the programme level. Unlike NAAC, NBA accredits specific courses (e.g. "CSE at X College") rather than the institution as a whole. Accreditation is granted for up to six years per cycle.

Why it matters

For engineering students, NBA accreditation of a specific branch is a stronger signal than institute-level NAAC — it says that branch, at that college, has cleared a quality floor on curriculum, faculty, and outcomes.

Common misconception

"The college is NAAC A+, so all branches are NBA accredited." Not necessarily. NBA is branch-by-branch — a top-rated college can have some branches accredited and others not.

NIRF · National Institutional Ranking Framework

#nirf
Definition

The Ministry of Education's annual ranking of Indian higher-education institutions, based on self-reported and verified data across five weighted parameters (TLR 30%, RPC 30%, GO 20%, OI 10%, PR 10%).

Why it matters

The closest thing to an audited ranking of Indian colleges, and the base layer for most of our canonical numbers.

Common misconception

NIRF rank = "best college." Not quite. NIRF heavily weights research (30%), which matters less to a student choosing a college for a placement outcome.

Placement rate

#placement-rate
Definition

The percentage of eligible students who received at least one job offer or are pursuing higher studies, as reported to NIRF for the most recent cycle.

Why it matters

The single most-asked number about any college. Also the most misinterpreted.

Common misconception

"90% placement" does NOT mean 90% of students got a job. It includes higher-studies enrollments and counts only students eligible per NIRF's definition — which excludes dropouts and those who didn't graduate on time.

Self-reported

#self-reported
Definition

A number provided by the college itself, without independent audit. NIRF data is self-reported to the Ministry of Education but is cross-checked during the ranking cycle; figures in a college brochure or on its own website are self-reported with no audit at all. unbiasEd marks unaudited self-reported figures at Medium confidence and always labels them as such.

Why it matters

Self-reported figures aren't automatically wrong — they're just shapeable. Knowing a number is self-reported lets you decide whether to anchor a decision on it.
