The Delhi High Court’s request for current data on postgraduate teacher vacancies has brought a long-running administrative problem inside government schools into sharper focus: a school may appear to have a teacher in every classroom, while still lacking stable subject-specific instruction for Classes XI and XII. The gap is being managed through guest teachers, shared subject specialists and redistribution of classes, but the arrangements do not necessarily provide continuity through an entire academic session.
The petition before the High Court alleges that 2,714 PGT posts are vacant across Delhi government schools and that appointments under the 50% promotion quota have remained stalled for around four years. The court has sought the government’s response and asked for the current vacancy position. A government official told The Times of India that the authorities have six weeks to compile the report.
The precise number of vacancies is therefore still part of the reporting process before the court. What is already clear from the accounts cited in the report is that schools are using temporary or shared staffing arrangements to keep classes functioning. That distinction matters. A vacant regular post does not automatically mean that no teacher is entering the classroom, but it can mean that teaching is dependent on a guest appointment, a teacher travelling between schools or an existing staff member taking on additional responsibility.
For senior-secondary students, the difference is not merely administrative. PGTs mainly teach Classes XI and XII, when students begin specialised subject study and prepare for school and board examinations. A regular teacher is expected not only to deliver lessons but also to complete the syllabus, conduct revision, answer subject-specific questions and track students’ progress over time. When staffing changes repeatedly or a specialist is available only on selected days, those functions become harder to sustain.
The system described in the report is a form of institutional substitution. Guest teachers fill vacancies, while shared staff allow a subject specialist to be deployed across more than one school. A principal in northeast Delhi said a biology teacher works at the school for three days a week and spends the remaining days at a nearby school. The arrangement keeps instruction going, but it also shows how one teacher is being made to serve multiple school communities rather than providing full-time support in one institution.
This is particularly consequential in science subjects. Education activist and lawyer Ashok Agarwal said student-classroom ratios remain exceptionally high in Classes XI and XII, especially in physics, chemistry and biology, while shortages of subject teachers and a lack of additional sections add to the difficulties. The report does not provide the ratios or the number of affected schools, so the scale of that pressure cannot be independently quantified from the available material. It does, however, identify the operational problem: demand for specialised teaching is concentrated in classes where replacing a teacher with a general redistribution of workload is least straightforward.
A case at GSKV Khajuri Khas illustrates how the problem is experienced at school level. Students alleged that they had gone without a regular chemistry teacher for up to three academic years, potentially affecting more than 200 students across four sections of Classes XI and XII. Following an earlier report, a teacher began taking classes three days a week, according to students. One Class XII student said the students hoped the teacher would not leave and that they had not been told whether the arrangement was permanent.
That uncertainty is central to the staffing question. A teacher’s presence on a timetable can resolve an immediate operational gap, but it does not establish whether the school has a stable teaching arrangement for the full year. Nor does it show whether the teacher has enough time to complete the syllabus, conduct practical work, provide individual support and prepare students for examinations. The available report does not establish how many schools rely on shared teachers, how frequently such teachers are moved between schools or how guest-teacher contracts align with the academic calendar.
The administrative structure helps explain why the gap can persist. According to officials cited by The Times of India, regular PGT appointments are made through direct recruitment and promotion under the applicable recruitment rules. The Delhi Subordinate Services Selection Board conducts examinations for direct recruitment, while eligible serving teachers may be promoted after meeting prescribed requirements. Half of the posts are earmarked for promotion under the quota referred to in the petition.
This creates two separate staffing channels, each with its own requirements and timing. Direct recruitment depends on the examination and selection process. Promotion depends on eligible teachers meeting prescribed conditions and on the department completing the relevant administrative steps. If one channel remains stalled, the vacancy does not simply disappear; the school system must continue operating through temporary appointments or internal redistribution.
The teachers’ association cited in the report described the time between a teacher’s retirement and a replacement joining as a recurring source of vacancies. Its general secretary, Ajay Veer Yadav, said guest teachers help cover that gap as well as emergency shortages, and that the education system would collapse without them. This establishes the practical dependence of schools on guest teachers, but it also points to a distinction between a contingency mechanism and a permanent staffing model. A system designed to bridge short intervals can become a long-term substitute when recruitment and promotion do not move at the same pace as retirements and demand.
Officials said the latest figures from earlier in the year showed 15,495 guest teachers working alongside around 44,000 regular teachers. At that time, 6,787 teaching posts across categories were vacant, with PGT posts forming only a portion of the total. These figures suggest that the staffing issue extends beyond one cadre, even though the court proceedings currently focus on PGT vacancies. They also show the scale of the temporary workforce: guest teachers account for a substantial presence alongside regular staff, rather than being a marginal emergency resource.
At the same time, the figures cannot by themselves show whether schools are adequately staffed. The number of guest teachers does not reveal how they are distributed across subjects, schools or grades. Nor does the total number of vacant posts indicate how many classrooms lack a teacher on a particular day. A school with a guest teacher may be operationally covered but still face instability if the teacher works part-time, is assigned late in the academic year or is replaced frequently. The High Court’s request for current, school-level vacancy information could therefore be important because aggregate totals may conceal uneven distribution.
The case also exposes a measurement problem in public-school administration. Counting sanctioned posts, filled posts, guest teachers and classrooms produces different pictures of staffing. A regular vacancy may be temporarily covered, but that coverage may not equal a full-time appointment. Similarly, a teacher assigned to two schools may appear in staffing records for both institutions while being physically present in only one on a given day. Without information on subject, timetable, duration and school-level deployment, it is difficult to assess whether the system is merely short of personnel or also misaligned in how available personnel are allocated.
The High Court’s intervention has not yet produced a final determination on the number of vacancies or the government’s responsibility for filling them. The government has six weeks to submit its report, according to the official quoted in the article. That report may clarify the current PGT vacancy position, the status of promotion appointments and the extent to which guest or shared teachers are being used to cover regular posts.
The evidence currently supports a narrower but significant conclusion. Delhi government schools are maintaining instruction despite regular PGT vacancies, but the means used to do so can weaken continuity for senior-secondary students. Guest teachers and shared staff are preventing an immediate breakdown in classroom operations; they are not, on the available evidence, proof that the underlying vacancies have been resolved. The next important development is the government’s submission to the High Court, which should show whether the reported figure of 2,714 vacancies reflects the current position and how the department proposes to address the promotion and recruitment gap.
