UPSC Combined Geo-Scientist Examination 2027: 127 posts and 22 September deadline

The UPSC Combined Geo-Scientist (Preliminary) Examination, 2027 is open from 2 September through 22 September 2026. The official examination page and Examination Notice No. 01/2027-GEOL set the application cutoff at 6:00 PM on 22 September, with the fee also due by that deadline. The notice lists 127 tentative vacancies across the Geological Survey of India (GSI) and the Central Ground Water Board (CGWB). The application is online through the UPSC portal, and the notice requires candidates to complete the registration, common application form and exam-specific module before submission. This is a specialist examination: the qualifying route depends on the stream and the postgraduate subject listed in the notice, not on a generic graduation label. Before applying, match your degree, age on 1 January 2027, category evidence and preferred stream with the full notice. The selection plan has a 400-mark objective Preliminary Examination, a 600-mark conventional Main Examination and a 200-mark personality test. The Preliminary Examination is scheduled for 10 January 2027, while the Main Examination is scheduled for 19 and 20 June 2027. The vacancy count and dates are stated as tentative and remain subject to the Commission's official updates. Use the UPSC examination page, the linked PDF notice and the official application portal as the controlling sources, and save the submitted application and payment record.

The 2027 examination notice is dated 2 September 2026 and refers to Examination Notice No. 01/2027-GEOL. It covers recruitment for posts connected with GSI under the Ministry of Mines and CGWB under the Ministry of Jal Shakti. The notification describes the vacancies as tentative: the Commission can alter the number or make other changes in accordance with the official notice and later government information. The current AvsarIQ opportunity record reflects the same 127-post total, online mode, 2 September start and 22 September closing date. The notice also makes the process more specific than a general government-job form. Candidates need a URN, a completed Common Application Form and the exam-specific application module. The portal uses photograph, signature and identity details in the online workflow. Keep the PDF open while selecting the stream because the education section differentiates geology, chemistry, geophysics and hydrogeology routes. An application accepted by the portal is not a substitute for checking the qualification and age clauses in the notice.

The official page gives the application window as 2 September to 22 September 2026, with the last application time at 6:00 PM on 22 September. The fee-payment deadline is recorded with the same closing date in the current opportunity data. The Preliminary Examination is scheduled for 10 January 2027. The Main Examination is scheduled for 19 and 20 June 2027. These dates are useful for planning, but the Commission's page and later notices control if a date is revised. There is no correction-window date in the current opportunity record, so check the portal's instructions before final submission and do not assume that an error can be fixed later. The notice provides the exam-specific online workflow and advises candidates to retain the final application. Plan time for account creation, uploading the required image and signature files, payment and confirmation rather than treating 6:00 PM as a safe upload time.

The notice lists qualifications by stream. For Geologist and Assistant Geologist routes, it describes a master's degree or an integrated master's course in geology, applied geology, geological science or another subject named in the detailed clause. The Chemistry routes require the prescribed master's-level chemistry qualification. Geophysics and related posts require the master's or integrated master's qualification in geophysics, applied geophysics, exploration geophysics or the equivalent subjects listed by the Commission. Hydrogeology routes use the geology, applied geology, marine geology or hydrogeology qualification routes specified in the notice. The exact wording, accepted combinations and the post-to-stream mapping must be checked in the PDF before form submission. A subject that sounds similar may not meet the clause. Candidates should keep the final degree certificate, provisional certificate, marksheets and any required proof of completion available. If the notice permits candidates awaiting a result or uses a cutoff for qualification, follow that precise rule rather than inferring it from a general postgraduate label. Select only the stream and post combination that your records can support at the required stage.

For the 2027 examination, the notice places the ordinary age reference on 1 January 2027 and gives the general age band as 21 to 32 years, subject to the relaxations and conditions written in the notice. The printed date-of-birth limits are 2 January 1995 through 1 January 2006 for the ordinary band. Reservation and other relaxations depend on the relevant government rules and valid certificates. The examination fee is ₹200. Female candidates, candidates belonging to SC or ST communities and Persons with Benchmark Disability are exempt as described in the notice; OBC and EWS candidates pay the prescribed fee unless another stated exemption applies. Use the payment modes allowed by UPSC and retain the transaction record. Before submitting, check the name, date of birth, category, photograph, signature, identity document and education entries against the source records. The notice's URN and CAF workflow means that the account and common form are part of the process, not optional preliminaries. Save the final application number or confirmation page where available.

The selection plan has three stages. The Preliminary Examination carries 400 marks and uses objective papers: a General Studies paper of 100 marks and a subject paper of 300 marks for the relevant stream, with each paper scheduled for two hours in the notice. The Commission applies negative marking as described in the examination notice, so candidates should read the paper instructions rather than assume that every attempted answer carries equal risk. The Main Examination carries 600 marks through three conventional papers of 200 marks for the relevant stream. The Personality Test carries 200 marks. The notice schedules the Preliminary Examination for 10 January 2027 and the Main Examination for 19 and 20 June 2027. These dates and the vacancy total are tentative. The full syllabus, paper combinations, qualifying provisions and later-stage instructions are in the official notice and must guide preparation. An application is the first step in the process; it does not itself secure an admit card, a place in the merit list or appointment.

The safest reading of the 2027 opportunity is a specialist UPSC examination with a clear but time-bound online window. The current official record is open, the notification is fresh, and the application cutoff is 6:00 PM on 22 September 2026. The 127 vacancy figure is useful for deciding whether to study the notice, but it is explicitly tentative. The qualification clauses, age rules, fee exemptions, document requirements and paper pattern determine whether a particular candidate can proceed. Start with the official notice, keep the UPSC page bookmarked and use only the official application portal for submission. If the Commission changes a date, vacancy count, qualification instruction or portal message, its later official notice takes precedence over this summary.
