CRITERIA FOR ASSESSMENT OF TRAINEES

Job Role: CAD Designer

Qualification Pack G&J/Q2303

Sector Skill Council Gem & Jewellery

Guidelines for Assessment

  1. Criteria for assessment for each Qualification Pack will be created by the Sector Skill Council. Each
    Performance Criteria (PC) will be assigned marks proportional to its importance in NOS. SSC will also lay
    down proportion of marks for Theory and Skills Practical for each PC.
  2. The assessment for the theory part will be based on knowledge bank of questions created by the SSC.
  3. Individual assessment agencies will create theory question papers for candidates at every
    examination/training centre. (as per assessment criteria below)
  4. Individual assessment agencies will create practical tests for skill evaluation for candidates at every
    examination/training centre. (as per assessment criteria below)
  5. To pass the Qualification Pack, every candidate should score a minimum of 50% in theory and 70% in
    practical to successfully clear the assessment.
  6. In case of successfully passing only certain number of NOS’s, the candidate is eligible to take subsequent
    assessment on the balance NOS’s to pass the Qualification Pack.
