TRAINER INSTRUCTIONS
This package has been compiled to assist Trainers in the on site, timely and accurate
correction of students written or verbal assessments. All pages of the “Assessment
Package” are to be returned to TAM Administration for the recording of the students
attainment.
Forms of Assessment
The trainer is required to obtain at least 3 types of evidence but preferably more. These
may include but are not limited to the following:1. Written or Verbal Assessment (the later for those with writing or literary
difficulties)
2. Observation by the Trainer of ‘on-site work’ called Practical Assessment for
work carried out on the student’s job site.
3. A Third Party Report completed by the employer after he is satisfied that the
student/trainee has demonstrated the required knowledge and skills consistently
whilst on the job.
4. A Photographic Record of work completed on site corroborated/signed by the
employer where possible with the trainee carrying out the actual work. These
photos should contain name, date, and the units that are supported by the
photographic evidence. (Only to be used as supportive evidence)
5. Other forms of evidence including recognition of prior learning and skills,
corroborated by a former employer accompanied by photographic evidence or a
CT being a credit transfer from a previous RTO where a trainee has already
completed some or all of that unit of competency.
