Practicals

28 hours of practicals To be conducted online or on-campus or in-house
Overview

Hands-on practicals are essential for learners to develop skills in operating and troubleshooting glass melting and conditioning equipment. Learners will work in a simulated or actual plant environment to apply theoretical knowledge.

Practical Activities
  • Practical 1: Batch Preparation and Furnace Start-up — Learners prepare a batch according to a given formula and assist in starting up a small-scale furnace under supervision. (6h)
  • Practical 2: Melting Process Monitoring and Control — Learners monitor melt temperature, glass level, and combustion parameters, and make adjustments to maintain optimal conditions. (8h)
  • Practical 3: Conditioning and Quality Inspection — Learners operate a conditioning forehearth, collect glass samples, and perform quality tests to assess homogeneity and defects. (8h)
  • Practical 4: Troubleshooting Simulation — Learners diagnose simulated faults in melting and conditioning processes and implement corrective actions. (6h)

Summatives

Each delegate is assessed continuously throughout the course via daily exercises, scored practical assignments, and a final summative test at the end.

Practical Assignments — 30%

Practical assignments are observed and scored against a rubric during the practical sessions. Each delegate's practical mark is averaged into a single 100% score and contributes 30% to the final total.

Daily Exercises — 20%

Every training day ends with a multiple-choice exercise scored out of 100%. The scores from each daily exercise are averaged across the duration of the course to produce a Daily Average mark, which contributes 20% to the final total.

Final Test — 50%

On the last day a final summative test is written. It is a multiple-choice paper with multiple-answer questions: each question may have more than one correct option, and a single wrong selection on a question marks the entire question wrong — no partial credit. The final test is scored out of 100% and contributes 50% to the overall mark.

Final Total
Component Out of Weight
Practical Assignments (rubric-scored) 100% 30%
Daily Average (multiple choice) 100% 20%
Final Test (multi-answer multiple choice) 100% 50%
Final Total 100%

All marks are recorded on the AATICD LMS and visible to each learner under their account.

Certificate

Certificate of Completion

Awarded to delegates who achieve an overall mark of 50% or higher on the Final Total (Practicals 30% + Daily Average 20% + Final Test 50%).

How it works
  • Certificates are auto-generated on the AATICD LMS as soon as the marks pass the 50% threshold.
  • Each certificate is a branded PDF with the delegate's name, the course title, the unit standard ID, NQF level, credits, and the date of issue.
  • You can download or print your certificate from your LMS dashboard at any time after issue — there's no reissue fee and no expiry date.
  • If you scored under 50% you can sit the final test again at the next scheduled session at no extra cost.
