DSSSB Recruitment 2026 – Delhi Subordinate Services Selection Board: Recruitment for 25 posts including Junior Scientific Assistant, TGT (Computer Science), Special Educator, I.T. Assistant G

The Delhi Subordinate Services Selection Board (DSSSB) is the statutory agency responsible for recruitment to Group 'B' and Group 'C' posts under various departments of the Government of NCT of Delhi. Established in the 1990s and reconstituted to improve transparency and efficiency, DSSSB conducts large-scale Computer Based Tests (CBTs), skill tests and interviews to fill posts across education, technical, clerical and scientific cadres.

DSSSB's mandate covers schools, laboratories, municipal and administrative departments within the National Capital Territory of Delhi. The board handles thousands of applications annually: recent recruitment drives have involved several lakh applicants and hundreds of examination centres across Delhi and neighbouring states. Because DSSSB posts offer regular pay, structured promotions and government benefits, it remains a sought-after employer among graduates, postgraduates and trade-qualified candidates in the Delhi region.

Junior Scientific Assistants (JSAs) are technical staff posted mainly in forensic laboratories, forensic science departments and crime branches under Delhi Police and other Delhi departments. Day-to-day duties for different specialisations vary but share operational and technical responsibilities:

• JSA (Biology/Chemistry): Prepare and run laboratory tests (microscopy, culture, biochemical assays, GC-MS/FTIR sample prep), maintain lab registers, record chain-of-custody for evidence, assist senior forensic scientists in report preparation.
• JSA (Ballistics): Handle ballistic evidence, operate comparison microscopes, maintain firing ranges for test-firings, prepare ballistic reports and assist ballistic experts during examinations.
• JSA (Lie-Detection): Assist in polygraph/lie-detection set-up, maintain equipment, prepare pre-test documentation, and attend to calibration and data extraction tasks under supervision.
• JSA (Documents/Finger Print/Photo/Cyber Forensic): Tasks include document examination, fingerprint analysis, photographic processing/digital enhancement, and basic cyber-forensic acquisition/analysis using forensics suites (e.g., FTK, Autopsy) respectively.

Most posts are office/laboratory-based (non-uniform). Work is supervised by Senior Scientific Officers/Head of Unit. Field visits (evidence collection at crime scenes) are common for Crime Scene/District Mobile Forensic Unit roles; expect a mix of desk and field duties with occasional requirements for shift or on-call work.

JSAs are placed at Pay Level 5 (Pay Matrix ₹29,200 – ₹92,300). Typical starting basic pay shown in notifications is ₹29,200. Allowances (subject to government rates) include Dearness Allowance (DA), House Rent Allowance (HRA) and Transport Allowance (TA):

• Basic pay: ₹29,200 (entry level for Level 5)
• HRA (Delhi - X cities): 24% of basic ≈ ₹7,008
• DA: Variable (paid as per government orders)
• Typical gross monthly pay (approx.): ₹36,000–₹40,000 depending on DA
• Approx. in-hand: After NPS (employee ~10% of basic), income tax and other statutory deductions, expect ₹28,000–₹34,000 per month in Delhi for Level 5 JSA posts.

Career progression: with experience and departmental promotion, a JSA can move to Senior Scientific Assistant/Technical Officer (Level 6/7) or equivalent grades in 5–10 years depending on vacancies and departmental seniority rules. Promotions often follow Departmental Promotion Committee (DPC) procedures and may require departmental exams or eligibility criteria.

• Medical benefits under CGHS (for centralized schemes) or Delhi government medical rules, depending on appointing department.
• Contributory retirement benefits under NPS (New Pension Scheme) or GPF where applicable.
• House Rent Allowance (HRA) and Transport Allowance (TA) as per city classification.
• Group insurance and accidental cover available for government employees.
• Casual leave, earned leave and study leave provisions as per departmental rules.
• Training opportunities: periodic in-service training at forensic science institutes and sponsored certification courses.
• For field-duty posts, risk or field allowance may be available depending on department rules.

Selection typically begins with a Computer Based Test (CBT) — a standard DSSSB pattern used across recruitments. For many technical posts the stages are:

• Tier-I (CBT): Objective multiple-choice questions covering General Awareness, General Intelligence & Reasoning, Arithmetical & Numerical Ability, and Language. Typical format used by DSSSB: 100 questions, 1 mark each, duration 90–120 minutes, negative marking (0.25 mark per wrong answer) for many recruitments. Check the specific notification for exact marks/time.
• Tier-II / Skill Test: For technical posts there may be a subject-specific CBT or practical/skill test (lab task, instrument operation, typing or trade test). IT and data posts require typing speed tests (8,000 KPH ≈ 26.67 WPM) or practical computer tests.
• Document Verification & Medical Examination: Final shortlisted candidates undergo DV and a medical fitness check.

Preparation tips:

• Start with previous DSSSB question papers (available on official site and standard coaching portals). Time yourself on 100-question mocks to build speed and accuracy.
• For subject papers (biology/chemistry/physics/computer science) use standard post-graduate-level textbooks plus practical manuals: e.g., R.K. Gupta for analytical chemistry techniques, Forensic Ballistics manuals for ballistics, and ‘‘Digital Forensics with Open Source Tools’’ for cyber-forensics basics.
• Practice instrument-related SOPs and common lab calculations (dilutions, titrations, concentration conversions). Practical familiarity helps in skill tests.
• Use mock tests from reputed portals (Adda247, Testbook, Gradeup) and join short focused coaching for laboratory-instrument topics if you lack hands-on exposure.

This recruitment is ideal for science postgraduates, technical diploma/degree holders and IT/ITeS candidates who want stable government careers in forensic science, laboratory work, school teaching and technical support roles. If you enjoy hands-on laboratory work, evidence handling, methodical documentation and occasional field visits, these JSA and technical posts offer rewarding, skill-based careers with clear promotion paths.

If you prefer purely desk-based, high-salary private sector roles or international research without structured bureaucracy, you may find government laboratory work slower-paced and administratively constrained. Compare this with Central Forensic Science Laboratory (CFSL) or state forensic labs for similar technical work but different promotion rules and posting areas.

Overall, this drive is a strong opportunity for science and technical candidates seeking secure employment in Delhi with professional training and government benefits.
