I was not registered as a Technician-in-training

Apply to be registered as a GISc Technologist with Plato on the pre scribed forms (See notes for guidance)

Since you were not registered you probably did not gain experience under the supervision of a mentor.

Provide an affidavit of a detail report of your practical GISc experience since you started your studies. Get a registered Technologist or Professional practitioner (Mentor) to sign of this experience.

If you can not find a suitable mentor, get any other professional person to sign it. In this case you also have to provide a copy of this persons CV and registration papers with whichever body he has registered with

Make sure your practical experience is enough and varied enough according to the "Notes for Guidance
