Who Can Apply and Why PET-2025 Matters

This is a mains-stage notification, not a fresh entry point. The Commission allows only those candidates to apply who hold the required qualification for a post and who appeared in the Preliminary Eligibility Test 2025 and received a PET-2025 scorecard. Your login for the online form is your PET-2025 registration number, and the OTP goes to the mobile number or email you registered at that stage.

Shortlisting for the written exam is also based on your PET-2025 normalised score. A candidate with a zero or negative absolute or normalised score will not be shortlisted. Candidates whose PET-2025 cases are marked under investigation or provisional can apply provisionally, but their shortlisting and selection stay subject to the outcome of the Commission's inquiry.

Important Dates

The Commission stresses that nothing is accepted after 25 November 2026, and your application printout is not available until the bank reconciles your fee. Pay early enough to reconcile by 25 November 2026, or within seven days after it, which means by 2 December 2026.

Application Fee

Candidates who apply under the dependents of freedom fighters, ex-servicemen, women, persons with disabilities and outstanding sportsperson categories pay according to the base category they belong to in the table above. The mains exam fee is separate. It is paid only by candidates shortlisted for the mains exam, and it must be paid before downloading the admit card.

Vacancy Details

Post-Wise and Category-Wise Vacancies

The 1156 posts are spread across eight post entries. The departments, not the Commission, supplied the requisitions, and the Commission published the reservation breakdown exactly as received. Vacancies are in the order UR (unreserved), SC, ST, OBC and EWS.

The Irrigation and Water Resources Directorate accounts for 458 posts across two entries, and Uttar Pradesh State Road Transport Corporation (UPSRTC) accounts for 398 posts across two entries. The Commission has also noted that the number of vacancies and the category-wise split can go up or down after the latest reservation orders are applied.

Horizontal Reservation Breakdown

The notification gives the horizontal reservation separately. Disability sub-categories appear as abbreviations: O.A. is one arm affected, O.L. is one leg affected, L.C. is leprosy cured, Dw. is dwarfism and A.A.V. is acid attack victims. Low Vision and Hard of Hearing are shown in their own columns. A dash means the notification shows no entry for that sub-category.

Pay Level by Post

Eligibility Criteria by Post

Qualifications differ from post to post, so read the row for the post you want. You need the required qualification in hand by 25 November 2026. Candidates must apply only for the posts whose educational requirements they fully meet, since the Commission does not advise on eligibility.

For the Technical Assistant (Mechanical) post in the Groundwater Department and the Public Works Department Junior Engineer post, the notification attaches letters from the Technical Education Council, Uttar Pradesh, and the Public Works Department that list the diploma courses treated as equivalent to a mechanical engineering diploma. The list for mechanical engineering includes automobile engineering, production engineering, tool and die making, mechatronics, refrigeration and air conditioning, fabrication technology and several related branches. Check the attached annexures in the original notification before you rely on an equivalent course.

Age Limit

Because this notification was published in October, the 1 July reference date applies to the UPSRTC posts as well. For SC, ST and other categories the government notifies from time to time, the upper age limit is raised by the number of years specified in the rules. For UPSRTC posts, candidates who already work in the Corporation get five more years on the upper limit. State government employees are allowed five years of relaxation in the maximum age, and researchers under the Chief Minister Fellowship get age and preference relaxation under the 2026 rules the notification cites. The exact number of relaxation years for each category is not printed in the notification.

Reservation and Certificate Rules

• Reservation for SC, ST, OBC and EWS applies as per the Uttar Pradesh government orders in force. Candidates who are not original residents of Uttar Pradesh do not get reservation benefits and are treated as unreserved.
• EWS candidates get 10 percent reservation. Family income from all sources in the financial year before the year of application must be below Rs. 8 lakh. The EWS certificate must be issued between 1 April 2026 and 25 November 2026, based on 2025-26 income and valid for 2026-27, in the format of the Personnel Department office memorandum dated 14 March 2019.
• Caste certificates must be issued by the competent authority in the prescribed format, on or before the date of application or the last date. A candidate claiming more than one reservation gets only the one that benefits more.
• For women of Uttar Pradesh, the caste certificate issued on the father's side is the one that counts, and they are placed in the same category they belong to.
• Persons with disabilities need a certificate in the latest format from the competent authority showing the type and percentage of disability. The Commission has re-identified posts to give 4 percent horizontal reservation in groups A, B, C and D, so disabled candidates must update their disability category and sub-category in the form.
• Ex-servicemen must have retired from service by 25 November 2026. Dependents of freedom fighters and ex-servicemen get reservation under the Uttar Pradesh Public Services (Reservation for Physically Handicapped, Dependents of Freedom Fighters and Ex-Servicemen) Act, 1993.
• Outstanding sportspersons from Uttar Pradesh must present a certificate in the prescribed format issued by the competent authority.

Selection Process

Selection for these posts rests on a written examination. The Commission follows a two-stage system in which the PET-2025 comes first and the mains exam second. The notification lists the exam plan approved by the government on 30 June 2026 and states that the exam date will be announced in due course.

How Candidates Are Shortlisted

For every category, candidates up to 15 times the number of vacancies advertised for a post are shortlisted for the written exam, in order of PET-2025 normalised score. Everyone who holds the same normalised score as the last shortlisted candidate, counted up to two decimal places, is shortlisted too. If the exam is held in more than one shift or on more than one day, the scores will be normalised under the rules of the Commission notice dated 22 May 2019.

Post Preference and Document Verification

Candidates have to give their post preferences at the time of document verification. The Commission will try to allot posts as per these preferences, keeping in mind availability, merit, the educational qualification needed for the post and the age limit, and its decision on allotment is final.

Fee Payment and Reconciliation
