SCL Technician B and Technical Assistant Selection Process 2026
The selection for SCL 2026 recruitment is carried out in two official stages followed by document verification and merit-based appointment. Below is a detailed walkthrough of each stage:
Stage 1: Computer-Based Test (CBT)
- The CBT is the primary qualifying and merit-determining examination.
- It consists of Part A (100 marks — General English, Quantitative Aptitude, General Intelligence & Logical Ability, General Knowledge/Current Affairs) and Part B (100 marks — Trade-Wise or Discipline-Wise Technical Curriculum).
- The test contains 200 Multiple Choice Questions (MCQs) for 200 marks in 120 minutes.
- Negative marking of 0.25 mark is applied for every incorrect answer.
Stage 2: Trade-Wise Skill Test
- Candidates who qualify the CBT (as per category-wise cutoffs) are called for a Trade-Wise Skill Test applicable to their applied trade or discipline.
- The Skill Test is qualifying in nature — it does not independently add marks to the final merit score.
- Candidates must secure the required qualifying percentage (50% for UR, 45% for OBC-NCL/EWS, 40% for SC/ST/PwBD/ESM).
Stage 3: Document Verification
- Shortlisted candidates must produce all original certificates (educational, category, experience, etc.) for eligibility verification.
- Failure to establish eligibility at this stage leads to disqualification.
Stage 4: Final Merit List & Appointment
- Final selection is based on CBT merit among candidates who have successfully qualified the Skill Test and all recruitment conditions.
- Appointment letters are issued based on the final merit list and medical fitness.

How to Prepare for SCL Technician B and Technical Assistant Exam 2026 – Expert Preparation Tips
Preparing for the SCL CBT requires a balanced approach between general subjects (Part A) and trade-specific technical knowledge (Part B). Here are 7 high-value preparation strategies to help you score above the qualifying cut-off:
- Master All Four Part A Subjects Daily: Dedicate at least 60–90 minutes each day to General English, Quantitative Aptitude, General Intelligence & Logical Ability, and General Knowledge/Current Affairs through regular objective-question practice. Since each subject carries 25 marks, neglecting even one can drop you below the 50% cutoff for UR category.
- Prioritize Part B (100 Marks): Part B constitutes 50% of the total exam. Choose the technical syllabus strictly matching your application trade or engineering discipline. Revise technical formulas, basic principles, and practical applications from your core textbooks and previous-year diploma/ITI curriculum.
- Practice Timed Mock Tests (120-Minute Format): The exam has a strict 120-minute duration (60 min Part A + 60 min Part B). Solve full-length mock tests in this exact time frame to build speed and accuracy. Allocate approximately 35–40 seconds per question in Part A and 35–40 seconds per question in Part B.
- Account for Negative Marking (-0.25): With a negative marking of 0.25 marks per wrong answer, strategic skipping is key. If you are unsure about a question, it is better to leave it blank than guess. Calculate your expected score after every mock to ensure you stay above 50% (100/200) for the UR category.
- Prepare for the Skill Test Simultaneously: The Skill Test is qualifying in nature and will be based on your trade/discipline. Practice hands-on practical tasks related to your trade (e.g., wiring for Electrician, drawing for Draughtsman, coding for CS) alongside CBT preparation.
- Stay Updated with Current Affairs: General Knowledge/Current Affairs accounts for 25 marks. Follow national and international news from the past 6–8 months, India’s economic policies, scientific developments, and events related to the Ministry of Electronics and Information Technology.
- Revise, Analyze, and Reattempt: Review every incorrect answer after each mock test. Maintain a separate error log for Part A (weak areas in English, Quant, Reasoning) and Part B (weak technical topics). Reattempt the same mock after a week to confirm improvement.
