INSTRUCTIONS

All sections of this e-workbook must be completed and the appropriate evidence provided to achieve the EduBit micro-credential for ‘Electric Vehicles: Introductory Health and Safety’.

All evidence must be submitted electronically via the EduBits website. Once you have achieved and been awarded this EduBit, you will receive an email with instructions of how to collect your EduBit micro-credential.

You will be required to submit electronically your completed electronic workbook, photographs of yourself indicating specific items and attestations (provided).

You are required to submit photographs as part of your assessment. Please refer to the website for the Photograph Tips document.

Should the evidence you provide in your e-workbook have minor gaps in evidence required you may be permitted to resubmit further evidence within ten (10) working days and have this work re-evaluated by the assessor at no charge.
