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. Assessment will be conducted for all compulsory NOS, and where applicable, on the selected elective/option NOS/set of NOS.
  4. Individual assessment agencies will create unique question papers for theory part for each candidate at each examination/training center (as per assessment criteria below).
  5. Individual assessment agencies will create unique evaluations for skill practical for every student at each examination/training center based on this criterion.
  6. To pass a QP, a trainee should score an average of 70% across generic NOS’ and a minimum of 70% for each technical NOS
  7. In case of unsuccessful completion, the trainee may seek reassessment on the Qualification Pack.
