Updates as of September 22, 2026
Computer Science carries 407 higher secondary posts in BPSC TRE 4, a figure reported identically by Physics Wallah, Testbook and Notifyhere. Testbook's category split of that total is roughly 213 unreserved, 48 EBC, 38 backward-class women, 36 BC, 28 SC, 17 EWS and 5 ST, which leaves several reserved cells in single or low double figures.
TestbookThe number of stages in TRE 4.0 is unresolved, and it is the single biggest open question in this cycle. BPSC's own exam calendar, dated 14 August 2026, lists TRE 4.0 at serial 30 with 32,388 vacancies under the heading 2 PHASE EXAMS (PT + MAINS), and records the exam date as TBD with the remark that the date of the PT shall be published after the completion of the advertisement period. On that document, TRE 4.0 is a two-stage recruitment with a screening preliminary test.
BPSC Exam Calendar dated 14 August 2026 (official)On 27 August 2026, nine days after Advertisement 14/2026 was issued, Bihar Chief Minister Samrat Choudhary announced that TRE 4.0 would be held in a single phase, scrapping the PT and Mains structure. The announcement followed a campaign by candidate representatives under the slogan One Exam, One Result. This is a state government statement rather than a BPSC order, and it directly contradicts the Commission's own calendar.
Testbook news report on the 27 August announcement (reported)As of 22 September 2026, BPSC has published no corrigendum on the TRE 4.0 examination pattern. The Commission's notices page carries corrigenda for the 72nd CCE and notices on the Stenographer examination and the new fifth answer option, but nothing on TRE. The 14 August calendar still shows PT plus Mains and has not been revised. The unresolved pattern is the most plausible reason the application window was postponed for procedural changes, and candidates should expect the revised pattern and the reopened window to be announced together.
BPSC notices page, checked 22 September 2026 (official)Computer Science has the widest qualification route of any higher secondary subject in this advertisement. Adda247's eligibility summary records that B.E., B.Tech, B.Sc., BCA and MCA are all recognised, and that B.Ed is not mandatory on certain computer science routes, unlike the postgraduate-plus-B.Ed requirement that applies elsewhere.
Adda247BPSC issued Advertisement No. 14/2026 for the fourth Teacher Recruitment Examination on 18 August 2026, covering 32,388 posts of which 16,101 are higher secondary. Career Power, Testbook, Adda247, Notifyhere and Physics Wallah all report the same advertisement number, date and totals.
Career PowerTRE 4 moves to a two-stage written examination with no interview — a 150-question preliminary of 2 hours, then a 150-question main of 2 hours 30 minutes, with 0.33 marks deducted per wrong answer at both stages, as reported by Adda247.
Adda247Applications were reported to open on 21 September 2026 after the originally advertised 1 September start was postponed. Notifyhere carries the revised start date; the last date, fee-payment cut-off and correction window were unannounced as of 22 September 2026.
NotifyhereA vacancy figure of 46,595 is circulating on job-alert aggregators for TRE 4.0. None of the aggregators carrying it cites an advertisement number or a date, and it is contradicted by both official BPSC documents that do carry a number: Advertisement 14/2026 of 18 August 2026 and the exam calendar of 14 August 2026, which state 32,388. Until BPSC publishes a corrigendum, 32,388 is the figure to plan against.
BPSC Exam Calendar dated 14 August 2026 (official)The Computer Science paper for classes 11-12 at a glance
| Part | Questions | Marks |
|---|---|---|
| Part I - Language | 30 of 150 | 30, qualifying only |
| Part II - General Studies | 40 of 150 | 40, counted in merit |
| Part III - Computer Science | 80 of 150 | 80, counted in merit |
| Preliminary stage | 150 in 2 hours | 150, screening only |
| Main stage total | 150 in 2h 30m | 150, negative 1/3 |
Career Power's syllabus page groups Computer Science with the vocational and skill subjects rather than with the academic science papers, and describes those subject sections as set at graduation or postgraduate level. That grouping is worth noting because it is consistent with the wider degree route: an engineering or MCA graduate can sit this paper, and the questions are pitched accordingly rather than at the class 11-12 textbook alone. The 30-40-80 split and the 2 hour 30 minute duration are reported identically by Career Power, Adda247 and BiharHelp. Read the structure below as the pattern for the written examination, not as a settled number of stages. BPSC's calendar of 14 August 2026 places TRE 4.0 under two-phase PT plus Mains exams; the Chief Minister announced a single-phase exam on 27 August 2026; and BPSC has published no corrigendum resolving the two as of 22 September 2026. The question paper described here is the one candidates must prepare for either way, because a single-phase exam would use it and a two-phase exam would use it as the main paper.

This calendar is common to every subject in BPSC TRE 4 — Computer Science has no separate notification, application window or examination date. The December-January window and the mid-October confirmation are Adda247's expectation rather than a BPSC announcement, and Physics Wallah's notification page still carries the superseded 1 to 30 September window.
What this means for your preparation
Computer Science candidates in this recruitment tend to misjudge the field rather than the syllabus. The wide qualification route — engineering, B.Sc., BCA and MCA all admitted, with B.Ed reportedly not mandatory on some paths — means 407 posts attract a far broader pool than a postgraduate-only subject of the same size would. The second misjudgement is preparing as a software professional rather than as a teacher of the class 11-12 Computer Science course, which is the content the paper is built on.
407 posts and an unusually open field
Physics Wallah, Testbook and Notifyhere all put Computer Science at 407 higher secondary posts, about two and a half per cent of the 16,101 at that level and roughly a ninth of Chemistry's count. Testbook's category breakdown of that total shows around 213 unreserved seats and only 5 for ST, 17 for EWS and 28 for SC, so several reserved cells are very small before any district split is applied. What makes the arithmetic harsher than the raw number suggests is the eligibility breadth Adda247 reports: B.E., B.Tech, B.Sc., BCA and MCA are all recognised routes, so the applicant base is not confined to M.Sc. Computer Science holders.
Where the Computer Science cut-off has sat
Career Power's compilation of previous-round class 11-12 cut-offs gives Computer Science an unreserved mark of about 63, with roughly 52 for unreserved women and for EWS, 57 for BC, 50 for EBC and 39 for SC. That places it well above the Chemistry figure of about 41 on the same page and below the Economics figure of about 73. The ordering is what matters: a small-vacancy subject with a broad eligibility route settles at a high cut-off. These numbers are compiled by a coaching portal from an earlier round rather than taken from BPSC's own subject-wise cut-off PDF, and they move with the vacancy count, so treat them as a level and not a target.
Prepare the school course, not the job stack
BPSC has published no topic-wise Computer Science syllabus for TRE 4. BiharHelp reports the notification as saying subject papers are based on SCERT and NCERT content, while Career Power groups the subject under vocational and skill subjects at graduation level. The reconcilable reading is the class 11 and 12 Computer Science course — computer systems and organisation, number systems and Boolean logic, Python programming and data types, functions and file handling, data structures such as stacks and queues, database concepts and SQL, and computer networks and cyber safety — examined at a depth a graduate should manage. Framework and industry-tooling knowledge earns nothing here.
Objective format punishes code-reading haste
With 150 questions in 150 minutes in the main paper, the average is one minute per question, and 0.33 of a mark comes off each wrong answer per Adda247; Physics Wallah says 0.25, the only pattern point the sources dispute. Computer Science items are unusually easy to get wrong quickly: an output-prediction question on a Python loop, an off-by-one on a list slice, an SQL clause order, a two's-complement conversion. Every one of those looks certain and is frequently mis-marked under time pressure. The practical discipline is to re-read the code fragment once before marking and to leave anything requiring a mental trace of more than a few iterations.
The parts that are not Computer Science
Only 80 of the 150 main-paper questions are subject questions. Part I's 30 language questions are qualifying, need 30 per cent, and add nothing to rank; Part II's 40 General Studies questions do count, and Career Power describes them as primary mathematics, general awareness, general science, the Indian national movement and geography. That block is 40 of the 110 merit-bearing marks. Against a cut-off reported near 63 for unreserved candidates in an earlier round, a technically strong candidate who ignores General Studies is conceding the cheapest marks in the paper. BiharHelp reports qualifying floors of 40 per cent general, 36.5 BC, 34 EBC and 32 for SC, ST, women and persons with benchmark disabilities.
Common questions
How many Computer Science posts are there in BPSC TRE 4 for classes 11-12?
Physics Wallah, Testbook and Notifyhere all report 407 Computer Science posts at the higher secondary level, out of 16,101 posts at that level in Advertisement No. 14/2026. Testbook's category split of the 407 is approximately 213 unreserved, 48 EBC, 38 backward-class women, 36 BC, 28 SC, 17 EWS and 5 ST. Those reserved cells are small before district allocation is applied, so district preference on the application form matters more than the state-level total suggests.
Is B.Ed required for BPSC TRE Higher Secondary Computer Science?
Adda247's eligibility summary reports that Computer Science recognises B.E., B.Tech, B.Sc., BCA and MCA qualifications and that B.Ed is not mandatory for certain computer science routes, which is a departure from the postgraduate-plus-B.Ed rule applied to other class 11-12 subjects. Because this is an exception rather than the general rule, and because aggregator summaries compress such clauses, the qualification annexure of the advertisement on the BPSC site should be read directly before applying. Age limits are 21 to 37 for general male candidates, 40 for general women and BC or EBC, 42 for SC, ST and transgender candidates.
What is the exam pattern for BPSC TRE Higher Secondary Computer Science?
The main paper has 150 objective questions for 150 marks in 2 hours 30 minutes: 30 language questions that are qualifying at 30 per cent and carry no merit weight, 40 General Studies questions that do count, and 80 Computer Science questions. A 150-question preliminary of 2 hours comes first and is a screening stage. Adda247 reports 0.33 marks deducted per wrong answer at both stages, while Physics Wallah's page states 0.25 — the single point on which the published accounts of the pattern disagree.
What is the syllabus for the BPSC TRE Computer Science subject paper?
BPSC has not released a topic-wise Computer Science syllabus for TRE 4. BiharHelp reports the notification as saying subject papers follow SCERT and NCERT content, while Career Power's syllabus page places Computer Science among vocational and skill subjects at graduation level. In practice that points at the class 11 and 12 Computer Science course — computer organisation, number systems and Boolean logic, Python programming, data structures, databases and SQL, and networking and cyber safety — set at a level that separates graduates. Detailed topic lists on coaching sites are reconstructions, not a BPSC specification.
What was the Computer Science cut-off in the previous BPSC TRE for class 11-12?
Career Power's cut-off compilation reports a class 11-12 Computer Science unreserved cut-off of about 63 from an earlier TRE round, with roughly 52 for unreserved women and EWS, 57 for BC, 50 for EBC and 39 for SC. On the same page Chemistry sits near 41 and Economics near 73. Note that Career Power's own TRE 3 result coverage lists only six class 11-12 subjects as having produced results, so the round these Computer Science figures belong to is not stated cleanly and they should be read as indicative only.
Does BPSC TRE 4 Computer Science have its own exam date?
No. All subjects in TRE 4 share one notification, one application window and one examination date; only the 80-question Part III differs by subject. Applications were reported to open on 21 September 2026 after the original 1 September start was postponed, and no closing date was confirmed as of 22 September 2026. Adda247 expects the examination in December 2026 or January 2027 with the schedule notified around mid-October 2026, but BPSC had not announced a date at the time of writing.
