UNIT STANDARD ACCREDITATION AND MODERATION OPTIONS 
The assessment of qualifying learners against this standard should meet the requirements of established assessment principles. It will be necessary to development assessment activities and tools, which are appropriate to the contexts in which qualifying learners are working. These activities and tools may include an appropriate combination of self-assessment and peer assessment; formative and summative assessment, portfolios and observations, etc.
The assessment should ensure that all the specific outcomes, critical cross-field outcomes and essential embedded knowledge be assessed.
The specific outcomes must be assessed through observation of performance. Supporting evidence should be used to prove competence of specific outcomes only when they are not clearly seen in the actual performance.
Essential embedded knowledge must be assessed in its own right, through oral and written evidence. It cannot be assessed by observation only.
The specific outcomes and essential embedded knowledge must be assessed in relation to each other. If a qualifying learner is able to explain the essential embedded knowledge but is unable to perform the specific outcomes, then they should not be assessed as competent. Similarly, if a qualifying learner is able to perform the specific outcomes but is unable to explain or justify their performance in terms of the essential embedded knowledge, they should not be assessed as competent.

Evidence of the specified critical cross-field outcomes should be found both in performance and in the essential embedded knowledge.
Performance of specific outcomes must actively affirm target groups of qualifying learners, not unfairly discriminate against them. Qualifying learners should be able to justify their performance in terms of these values.

1 Anyone assessing a learner against this unit standard must be registered as an assessor with the relevant ETQA.
2. Any institution offering learning that will enable achievement of this unit standard or assessing this unit standard must be accredited as a provider with the relevant ETQA.
3 Moderation of assessment will be overseen by the relevant ETQA according to the moderation guidelines in the relevant qualification and the agreed ETQA procedures.

1. Value of chemical control of weeds
2. Dangers attached to working with chemicals
3. Legal requirements when working with chemicals
4. Dangers attached to wind drift of chemicals
5. Importance of maintaining herbicide application equipment.

PROVIDERS CURRENTLY ACCREDITED TO OFFER THIS UNIT STANDARD: 
This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
