Criteria For Assessment Of Trainees
Job Role Planner – Diamond Processing
Qualification Pack G&J/Q4205
Sector Skill Council Gem & Jewellery
Guidelines for Assessment
- 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. - The assessment for the theory part will be based on knowledge bank of questions created by the SSC.
- Assessment will be conducted for all compulsory NOS, and where applicable, on the selected elective/option
NOS/set of NOS. - Individual assessment agencies will create unique question papers for theory part for each candidate at each
examination/training center (as per assessment criteria below). - Individual assessment agencies will create unique evaluations for skill practical for every student at each
examination/training center based on this criterion. - To pass the Qualification Pack, every trainee should score a minimum of 70% of aggregate marks to successfully
clear the assessment. - In case of unsuccessful completion, the trainee may seek reassessment on the Qualification Pack.
