There are three basic assessor roles. Assessor, Assessor Trainer and Principal Assessor.
Assessors need to demonstrate an understanding of the ICT they are assessing but more importantly that they have the capacity to learn new skills and are willing to up date their skills as technologies change and to pass these values on to the learners.
Assessor training prepares the assessor for these expectations and the administrative procedures and quality assurance built into the INGOTs.
Assessor trainers are more experienced in ICT assessment and usually they will be qualified teachers. They have the authority to create assessor accounts on the web site for colleagues that demonstrate the capability of assessing accurately and consistently.
The Principal Assessor is an assessor trainer who takes responsibility for the consistency of standards in the Academy or Centre. Assessor status can be granted at Bronze, Silver or Gold levels depending on the experience of the individual.
The INGOT assessor model provides many opportunities for teachers to use their learning to provide evidence for recognition through the stages in the TLA framework[3]. Here[4] is an example of a presentation using the INGOT assessor training and practical professional development for Stage 1 recognition.
