Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

Assess germinated seeds

  1. All un-germinated seeds and abnormal seedlings are counted off and the number recorded.
  2. Normal seedlings are examined under ultra violet light.
  3. Normal seedlings that have fluorescent roots under ultra violet light are counted off and the number recorded.
  4. Normal seedlings that do not have fluorescent roots under ultra violet light are counted off and the number recorded.
  5. Exposure of bare skin to ultra violet light is minimised.
  6. Enterprise worksheet is completed.

Instructions to Assessors

Evidence Guide

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this Unit

Evidence of the ability to:

prepare replicates from working sample

assess seedlings using ultra violet light

counting and recording of results.

Context of and specific resources for assessment

Competency requires the application of work practices under work conditions. Selection and use of resources for some worksites may differ due to the regional or enterprise circumstances.

Method of assessment

This Unit should be assessed together with core Units and other Units of Competency relevant to the function or work role.

Guidance information for assessment

To ensure consistency of performance, competency should be demonstrated on more than one occasion over a period of time in order to cover a variety of circumstances, cases and responsibilities, and where possible, over a number of assessment activities.

Required Skills and Knowledge

Required skills include:

Ability to:

assess seedlings under ultra violet light

follow enterprise guidelines and standard operating procedures

germinate seed

prepare replicates for testing

record results

Required knowledge includes:

Knowledge of:

the role of the International Seed Testing Association (ISTA) and the ISTA Rules for Seed Testing

fluorescence testing procedures

seed biology

enterprise and/or legal traceability requirements

enterprise standard operating procedures (SOPs)

relevant health, safety and environment requirements

Range Statement

The range statement relates to the Unit of Competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Seed may include:

bare seed; treated seed; and coated seed that has been prepared as required.
