Practicals

No practicals for this training.

This course is made up of exercises and case studies delivered alongside the theory — no separate practical sessions are required to complete it.

Summatives

Each delegate is assessed continuously throughout the course and a final summative test at the end.

Daily Exercises — 30%

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 30% to the final total.

Final Test — 70%

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 70% to the overall mark.

Final Total
Component Out of Weight
Daily Average (multiple choice) 100% 30%
Final Test (multi-answer multiple choice) 100% 70%
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 (Daily Average 30% + Final Test 70%).

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.
