India’s premier engineering institutes have made significant progress in filling faculty vacancies, with the Centre informing the Lok Sabha that more than 3,500 faculty positions across the IIT system were filled between September 2022 and May 2026.
The recruitment was carried out under a mission-mode drive aimed at addressing faculty shortages in the Indian Institutes of Technology (IITs).
Yet, behind the headline figure lies a more complicated picture.
The latest parliamentary response does not provide the actual faculty-to-student ratio for individual IITs, nor does it give a consolidated institute-wise breakdown of sanctioned, filled and vacant posts for the period sought. This has renewed questions over whether faculty recruitment has kept pace with the rapid expansion of student intake and academic programmes across the IIT system.
What Was Asked in the Lok Sabha?
The issue was raised through a series of questions in the Lok Sabha seeking greater clarity on the IIT faculty-student ratio and faculty vacancies.
The questions sought information on:
- Whether a prescribed faculty-to-student ratio exists for IITs
- The actual ratio at individual IITs
- The number of permanent and visiting faculty members
- Sanctioned, filled and vacant faculty posts
- Steps being taken to attract doctoral scholars and alumni into permanent faculty positions
- Measures to convert long-serving visiting or ad-hoc faculty members into permanent positions
The Centre’s response provided details about recruitment initiatives but did not supply all the institute-wise data requested.
This distinction is important because the number of faculty members recruited tells only part of the story. What ultimately matters for students is whether sufficient teachers are available relative to the number of students and courses being offered.
Over 3,500 Faculty Vacancies Filled Since 2022
According to the Ministry of Education, all Central Higher Educational Institutions were advised in September 2022 to undertake recruitment in mission mode.
IITs subsequently filled more than 3,500 faculty vacancies between September 2022 and May 2026.
The government also pointed out that faculty recruitment is a continuous process because vacancies arise for several reasons, including:
- Retirement
- Resignation
- Expansion of student enrolment
- Introduction of new academic programmes
- Creation of additional faculty positions
IITs therefore continue to issue recruitment advertisements throughout the year rather than relying on a single recruitment cycle.
The scale of recruitment indicates that the government and IITs have recognised faculty availability as an important issue for maintaining academic quality while the institutes expand.
Why Faculty-Student Ratio Matters at IITs
The faculty-student ratio is more than a statistical indicator.
A lower student load per faculty member can allow teachers to devote more time to:
- Classroom teaching
- Laboratory instruction
- Research supervision
- PhD guidance
- Student mentoring
- Academic projects
- Innovation and industry collaboration
This becomes particularly important at IITs, where education is closely linked with research and postgraduate programmes.
A rapidly increasing student population without a corresponding expansion in faculty strength can place additional pressure on teaching and research ecosystems.
What Is the IIT Faculty-Student Ratio Norm?
An earlier parliamentary response in August 2025 stated that faculty posts in IITs are sanctioned on the basis of a 1:10 faculty-to-student ratio.
However, the latest parliamentary response does not disclose the current actual ratio at each IIT.
That leaves an important gap in the public picture.
For example, filling 3,500 vacancies does not automatically establish that every IIT now meets the 1:10 benchmark. The ratio depends on two moving numbers — faculty strength and student enrolment.
If student numbers increase substantially while recruitment also rises, an institute could still face pressure despite filling thousands of positions.
IITs Still Have Around 460 Visiting Faculty
The government has also highlighted the role of non-permanent academic appointments.
According to the latest response, approximately 460 visiting faculty members are currently engaged across the IIT system.
IITs also use:
- Guest faculty
- Adjunct faculty
- Visiting professors
- Professors of Practice
These appointments can help institutions bring specialised expertise into classrooms and research environments.
Visiting and adjunct faculty can be particularly useful when an institute needs expertise in emerging areas or wants to connect students with experienced professionals from industry and research.
However, these arrangements are not necessarily substitutes for a stable permanent faculty base. The distinction becomes important when assessing long-term teaching capacity, research supervision and institutional academic continuity.
IIT Council’s Earlier PhD Scholar Proposal Explained
The faculty shortage debate is not new.
In 2016, when IITs were facing a significant faculty gap, an IIT Council proposal suggested that five PhD scholars could be counted as equivalent to one faculty member for the purpose of calculating the student-teacher ratio.
The argument was that doctoral scholars also contribute to undergraduate teaching.
At the time, the IIT system had approximately 26,000 PhD scholars, meaning that the proposed calculation could potentially have translated into around 5,000 faculty-equivalent positions.
The proposal reflected the pressure IITs were facing in meeting their desired faculty-student ratio.
However, treating PhD scholars as faculty-equivalent positions is conceptually different from recruiting permanent professors. PhD scholars have their own research and academic responsibilities, while permanent faculty members carry broader responsibilities for teaching, research, supervision and institutional work.
The Vacancy Problem Has Persisted for Years
The latest recruitment figures should also be viewed against the historical backdrop.
An August 2022 parliamentary response had put the number of vacant teaching positions across the 23 IITs at 4,596.
The subsequent mission-mode recruitment programme was intended to tackle this backlog.
The fact that more than 3,500 vacancies were filled between September 2022 and May 2026 represents substantial recruitment. But faculty positions can simultaneously become vacant because of retirement, resignation and institutional expansion.
This explains why the Ministry describes faculty recruitment as a continuous process rather than a problem that can be permanently solved through one recruitment drive.
The Missing Institute-Wise Data Matters
One of the most notable aspects of the latest parliamentary response is what it does not reveal.
The response does not provide the current faculty-student ratio for each IIT.
That makes it difficult to determine whether the situation is uniform across the IIT system.
The 23 IITs differ significantly in size, student population, academic programmes, research activity and faculty requirements. A system-wide recruitment figure can therefore conceal differences between individual institutions.
For students and policymakers, institute-wise information would provide a clearer picture of where faculty shortages remain concentrated.
IIT Faculty Recruitment: What the Government Is Doing
The Centre has outlined several measures discussed through the IIT Council to strengthen faculty recruitment.
These include:
Rolling recruitment drives:
IITs continue to advertise faculty positions throughout the year.
Special recruitment campaigns:
Institutes can conduct focused recruitment drives to fill specific shortages.
International recruitment:
The IIT Council has discussed attracting foreign faculty and eligible Overseas Citizen of India (OCI) cardholders.
Performance monitoring:
Recruitment and institutional performance are being monitored through the IIT Council mechanism.
Alternative academic appointments:
Visiting, guest, adjunct faculty and Professors of Practice are being used to supplement academic resources.
Together, these measures indicate an attempt to broaden the faculty recruitment pool while responding to changing institutional needs.
